[![Go Report Card](https://goreportcard.com/badge/github.com/deckarep/golang-set)](https://goreportcard.com/report/github.com/deckarep/golang-set)

## golang-set
The missing set collection for the Go language. Until Go has sets built-in...use this.
Coming from Python one of the things I miss is the superbly wonderful set collection. This is my attempt to mimic the primary features of the set from Python.
You can of course argue that there is no need for a set in Go, otherwise the creators would have added one to the standard library. To those I say simply ignore this repository
and carry-on and to the rest that find this useful please contribute in helping me make it better by:
* Helping to make more idiomatic improvements to the code.
* Helping to increase the performance of it. ~~(So far, no attempt has been made, but since it uses a map internally, I expect it to be mostly performant.)~~
* Helping to make the unit-tests more robust and kick-ass.
* Helping to fill in the [documentation.](http://godoc.org/github.com/deckarep/golang-set)
* Simply offering feedback and suggestions. (Positive, constructive feedback is appreciated.)
I have to give some credit for helping seed the idea with this post on [stackoverflow.](http://programmers.stackexchange.com/questions/177428/sets-data-structure-in-golang)
*Update* - as of 3/9/2014, you can use a compile-time generic version of this package in the [gen](http://clipperhouse.github.io/gen/) framework. This framework allows you to use the golang-set in a completely generic and type-safe way by allowing you to generate a supporting .go file based on your custom types.
## Features (as of 9/22/2014)
* a CartesianProduct() method has been added with unit-tests: [Read more about the cartesian product](http://en.wikipedia.org/wiki/Cartesian_product)
## Features (as of 9/15/2014)
* a PowerSet() method has been added with unit-tests: [Read more about the Power set](http://en.wikipedia.org/wiki/Power_set)
## Features (as of 4/22/2014)
* One common interface to both implementations
* Two set implementations to choose from
* a thread-safe implementation designed for concurrent use
* a non-thread-safe implementation designed for performance
* 75 benchmarks for both implementations
* 35 unit tests for both implementations
* 14 concurrent tests for the thread-safe implementation
Please see the unit test file for additional usage examples. The Python set documentation will also do a better job than I can of explaining how a set typically [works.](http://docs.python.org/2/library/sets.html) Please keep in mind
however that the Python set is a built-in type and supports additional features and syntax that make it awesome.
## Examples but not exhaustive:
```go
requiredClasses := mapset.NewSet()
requiredClasses.Add("Cooking")
requiredClasses.Add("English")
requiredClasses.Add("Math")
requiredClasses.Add("Biology")
scienceSlice := []interface{}{"Biology", "Chemistry"}
scienceClasses := mapset.NewSetFromSlice(scienceSlice)
electiveClasses := mapset.NewSet()
electiveClasses.Add("Welding")
electiveClasses.Add("Music")
electiveClasses.Add("Automotive")
bonusClasses := mapset.NewSet()
bonusClasses.Add("Go Programming")
bonusClasses.Add("Python Programming")
//Show me all the available classes I can take
allClasses := requiredClasses.Union(scienceClasses).Union(electiveClasses).Union(bonusClasses)
fmt.Println(allClasses) //Set{Cooking, English, Math, Chemistry, Welding, Biology, Music, Automotive, Go Programming, Python Programming}
//Is cooking considered a science class?
fmt.Println(scienceClasses.Contains("Cooking")) //false
//Show me all classes that are not science classes, since I hate science.
fmt.Println(allClasses.Difference(scienceClasses)) //Set{Music, Automotive, Go Programming, Python Programming, Cooking, English, Math, Welding}
//Which science classes are also required classes?
fmt.Println(scienceClasses.Intersect(requiredClasses)) //Set{Biology}
//How many bonus classes do you offer?
fmt.Println(bonusClasses.Cardinality()) //2
//Do you have the following classes? Welding, Automotive and English?
fmt.Println(allClasses.IsSuperset(mapset.NewSetFromSlice([]interface{}{"Welding", "Automotive", "English"}))) //true
```
Thanks!

// Package mapset implements a simple and generic set collection.

# Contributing
Thank you for considering to help out with the source code! We welcome
contributions from anyone on the internet, and are grateful for even the
smallest of fixes!
If you'd like to contribute to go-ethereum, please fork, fix, commit and send a
pull request for the maintainers to review and merge into the main code base. If
you wish to submit more complex changes though, please check up with the core
devs first on [our gitter channel](https://gitter.im/ethereum/go-ethereum) to
ensure those changes are in line with the general philosophy of the project
and/or get some early feedback which can make both your efforts much lighter as
well as our review and merge procedures quick and simple.
## Coding guidelines
Please make sure your contributions adhere to our coding guidelines:
* Code must adhere to the official Go
[formatting](https://golang.org/doc/effective_go.html#formatting) guidelines
(i.e. uses [gofmt](https://golang.org/cmd/gofmt/)).
* Code must be documented adhering to the official Go
[commentary](https://golang.org/doc/effective_go.html#commentary) guidelines.
* Pull requests need to be based on and opened against the `master` branch.
* Commit messages should be prefixed with the package(s) they modify.
* E.g. "eth, rpc: make trace configs optional"
## Can I have feature X
Before you do a feature request please check and make sure that it isn't possible
through some other means. The JavaScript enabled console is a powerful feature
in the right hands. Please check our [Wiki page](https://github.com/ethereum/go-ethereum/wiki) for more info

| Command | Description |
|:----------:|-------------|
| **`geth`** | Our main Ethereum CLI client. It is the entry point into the Ethereum network (main-, test- or private net), capable of running as a full node (default) archive node (retaining all historical state) or a light node (retrieving data live). It can be used by other processes as a gateway into the Ethereum network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports. `geth --help` and the [CLI Wiki page](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options) for command line options. |

| `abigen` | Source code generator to convert Ethereum contract definitions into easy to use, compile-time type-safe Go packages. It operates on plain [Ethereum contract ABIs](https://github.com/ethereum/wiki/wiki/Ethereum-Contract-ABI) with expanded functionality if the contract bytecode is also available. However it also accepts Solidity source files, making development much more streamlined. Please see our [Native DApps](https://github.com/ethereum/go-ethereum/wiki/Native-DApps:-Go-bindings-to-Ethereum-contracts) wiki page for details. |
| `bootnode` | Stripped down version of our Ethereum client implementation that only takes part in the network node discovery protocol, but does not run any of the higher level application protocols. It can be used as a lightweight bootstrap node to aid in finding peers in private networks. |
| `evm` | Developer utility version of the EVM (Ethereum Virtual Machine) that is capable of running bytecode snippets within a configurable environment and execution mode. Its purpose is to allow isolated, fine-grained debugging of EVM opcodes (e.g. `evm --code 60ff60ff --debug`). |
| `gethrpctest` | Developer utility tool to support our [ethereum/rpc-test](https://github.com/ethereum/rpc-tests) test suite which validates baseline conformity to the [Ethereum JSON RPC](https://github.com/ethereum/wiki/wiki/JSON-RPC) specs. Please see the [test suite's readme](https://github.com/ethereum/rpc-tests/blob/master/README.md) for details. |
| `rlpdump` | Developer utility tool to convert binary RLP ([Recursive Length Prefix](https://github.com/ethereum/wiki/wiki/RLP)) dumps (data encoding used by the Ethereum protocol both network as well as consensus wise) to user friendlier hierarchical representation (e.g. `rlpdump --hex CE0183FFFFFFC4C304050583616263`). |
| `swarm` | swarm daemon and tools. This is the entrypoint for the swarm network. `swarm --help` for command line options and subcommands. See https://swarm-guide.readthedocs.io for swarm documentation. |
| `swarm` | Swarm daemon and tools. This is the entrypoint for the Swarm network. `swarm --help` for command line options and subcommands. See [Swarm README](https://github.com/ethereum/go-ethereum/tree/master/swarm) for more information. |

/*
Binary Merkle Tree Hash is a hash function over arbitrary datachunks of limited size
It is defined as the root hash of the binary merkle tree built over fixed size segments
of the underlying chunk using any base hash function (e.g keccak 256 SHA3)
It is used as the chunk hash function in swarm which in turn is the basis for the
128 branching swarm hash http://swarm-guide.readthedocs.io/en/latest/architecture.html#swarm-hash
The BMT is optimal for providing compact inclusion proofs, i.e. prove that a
segment is a substring of a chunk starting at a particular offset
The size of the underlying segments is fixed at 32 bytes (called the resolution
of the BMT hash), the EVM word size to optimize for on-chain BMT verification
as well as the hash size optimal for inclusion proofs in the merkle tree of the swarm hash.
Two implementations are provided:
* RefHasher is optimized for code simplicity and meant as a reference implementation
* Hasher is optimized for speed taking advantage of concurrency with minimalistic
control structure to coordinate the concurrent routines
It implements the ChunkHash interface as well as the go standard hash.Hash interface

Clef
----
Clef can be used to sign transactions and data and is meant as a replacement for geth's account management.
This allows DApps not to depend on geth's account management. When a DApp wants to sign data it can send the data to
the signer, the signer will then provide the user with context and asks the user for permission to sign the data. If
the users grants the signing request the signer will send the signature back to the DApp.
This setup allows a DApp to connect to a remote Ethereum node and send transactions that are locally signed. This can
help in situations when a DApp is connected to a remote node because a local Ethereum node is not available, not
synchronised with the chain or a particular Ethereum node that has no built-in (or limited) account management.
Clef can run as a daemon on the same machine, or off a usb-stick like [usb armory](https://inversepath.com/usbarmory),
or a separate VM in a [QubesOS](https://www.qubes-os.org/) type os setup.
Check out
* the [tutorial](tutorial.md) for some concrete examples on how the signer works.
* the [setup docs](docs/setup.md) for some information on how to configure it to work on QubesOS or USBArmory.
## Command line flags
Clef accepts the following command line options:
```
COMMANDS:
init Initialize the signer, generate secret storage
attest Attest that a js-file is to be used
addpw Store a credential for a keystore file
help Shows a list of commands or help for one command
GLOBAL OPTIONS:
--loglevel value log level to emit to the screen (default: 4)
--keystore value Directory for the keystore (default: "$HOME/.ethereum/keystore")
--configdir value Directory for clef configuration (default: "$HOME/.clef")
--networkid value Network identifier (integer, 1=Frontier, 2=Morden (disused), 3=Ropsten, 4=Rinkeby) (default: 1)
--lightkdf Reduce key-derivation RAM & CPU usage at some expense of KDF strength
--nousb Disables monitoring for and managing USB hardware wallets
--rpcaddr value HTTP-RPC server listening interface (default: "localhost")
--rpcport value HTTP-RPC server listening port (default: 8550)
--signersecret value A file containing the password used to encrypt signer credentials, e.g. keystore credentials and ruleset hash
--4bytedb value File containing 4byte-identifiers (default: "./4byte.json")
--4bytedb-custom value File used for writing new 4byte-identifiers submitted via API (default: "./4byte-custom.json")
--auditlog value File used to emit audit logs. Set to "" to disable (default: "audit.log")
--rules value Enable rule-engine (default: "rules.json")
--stdio-ui Use STDIN/STDOUT as a channel for an external UI. This means that an STDIN/STDOUT is used for RPC-communication with a e.g. a graphical user interface, and can be used when the signer is started by an external process.
--stdio-ui-test Mechanism to test interface between signer and UI. Requires 'stdio-ui'.
--help, -h show help
--version, -v print the version
```
Example:
```
signer -keystore /my/keystore -chainid 4
```
## Security model
The security model of the signer is as follows:
* One critical component (the signer binary / daemon) is responsible for handling cryptographic operations: signing, private keys, encryption/decryption of keystore files.
* The signer binary has a well-defined 'external' API.
* The 'external' API is considered UNTRUSTED.
* The signer binary also communicates with whatever process that invoked the binary, via stdin/stdout.
* This channel is considered 'trusted'. Over this channel, approvals and passwords are communicated.
The general flow for signing a transaction using e.g. geth is as follows:
![image](sign_flow.png)
In this case, `geth` would be started with `--externalsigner=http://localhost:8550` and would relay requests to `eth.sendTransaction`.
## TODOs
Some snags and todos
* [ ] The signer should take a startup param "--no-change", for UIs that do not contain the capability
to perform changes to things, only approve/deny. Such a UI should be able to start the signer in
a more secure mode by telling it that it only wants approve/deny capabilities.
* [x] It would be nice if the signer could collect new 4byte-id:s/method selectors, and have a
secondary database for those (`4byte_custom.json`). Users could then (optionally) submit their collections for
inclusion upstream.
* It should be possible to configure the signer to check if an account is indeed known to it, before
passing on to the UI. The reason it currently does not, is that it would make it possible to enumerate
accounts if it immediately returned "unknown account".
* [x] It should be possible to configure the signer to auto-allow listing (certain) accounts, instead of asking every time.
* [x] Done Upon startup, the signer should spit out some info to the caller (particularly important when executed in `stdio-ui`-mode),
invoking methods with the following info:
* [x] Version info about the signer
* [x] Address of API (http/ipc)
* [ ] List of known accounts
* [ ] Have a default timeout on signing operations, so that if the user has not answered within e.g. 60 seconds, the request is rejected.
* [ ] `account_signRawTransaction`
* [ ] `account_bulkSignTransactions([] transactions)` should
* only exist if enabled via config/flag
* only allow non-data-sending transactions
* all txs must use the same `from`-account
* let the user confirm, showing
* the total amount
* the number of unique recipients
* Geth todos
- The signer should pass the `Origin` header as call-info to the UI. As of right now, the way that info about the request is
put together is a bit of a hack into the http server. This could probably be greatly improved
- Relay: Geth should be started in `geth --external_signer localhost:8550`.
- Currently, the Geth APIs use `common.Address` in the arguments to transaction submission (e.g `to` field). This
type is 20 `bytes`, and is incapable of carrying checksum information. The signer uses `common.MixedcaseAddress`, which
retains the original input.
- The Geth api should switch to use the same type, and relay `to`-account verbatim to the external api.
* [x] Storage
* [x] An encrypted key-value storage should be implemented
* See [rules.md](rules.md) for more info about this.
* Another potential thing to introduce is pairing.
* To prevent spurious requests which users just accept, implement a way to "pair" the caller with the signer (external API).
* Thus geth/mist/cpp would cryptographically handshake and afterwards the caller would be allowed to make signing requests.
* This feature would make the addition of rules less dangerous.
* Wallets / accounts. Add API methods for wallets.
## Communication
### External API
The signer listens to HTTP requests on `rpcaddr`:`rpcport`, with the same JSONRPC standard as Geth. The messages are
expected to be JSON [jsonrpc 2.0 standard](http://www.jsonrpc.org/specification).
Some of these call can require user interaction. Clients must be aware that responses
may be delayed significantly or may never be received if a users decides to ignore the confirmation request.
The External API is **untrusted** : it does not accept credentials over this api, nor does it expect
that requests have any authority.
### UI API
The signer has one native console-based UI, for operation without any standalone tools.
However, there is also an API to communicate with an external UI. To enable that UI,
the signer needs to be executed with the `--stdio-ui` option, which allocates the
`stdin`/`stdout` for the UI-api.
An example (insecure) proof-of-concept of has been implemented in `pythonsigner.py`.
The model is as follows:
* The user starts the UI app (`pythonsigner.py`).
* The UI app starts the `signer` with `--stdio-ui`, and listens to the
process output for confirmation-requests.
* The `signer` opens the external http api.
* When the `signer` receives requests, it sends a `jsonrpc` request via `stdout`.
* The UI app prompts the user accordingly, and responds to the `signer`
* The `signer` signs (or not), and responds to the original request.
## External API
See the [external api changelog](extapi_changelog.md) for information about changes to this API.
### Encoding
- number: positive integers that are hex encoded
- data: hex encoded data
- string: ASCII string
All hex encoded values must be prefixed with `0x`.
## Methods
### account_new
#### Create new password protected account
The signer will generate a new private key, encrypts it according to [web3 keystore spec](https://github.com/ethereum/wiki/wiki/Web3-Secret-Storage-Definition) and stores it in the keystore directory.
The client is responsible for creating a backup of the keystore. If the keystore is lost there is no method of retrieving lost accounts.
#### Arguments
None
#### Result
- address [string]: account address that is derived from the generated key
- url [string]: location of the keyfile
#### Sample call
```json

}
}
```
### account_list
#### List available accounts
List all accounts that this signer currently manages
#### Arguments
None
#### Result
- array with account records:
- account.address [string]: account address that is derived from the generated key
- account.type [string]: type of the

### account_signTransaction
#### Sign transactions
Signs a transactions and responds with the signed transaction in RLP encoded form.
#### Arguments
2. transaction object:
- `from` [address]: account to send the transaction from
- `to` [address]: receiver account. If omitted or `0x`, will cause contract creation.
- `gas` [number]: maximum amount of gas to burn

- `value` [number:optional]: amount of Wei to send with the transaction
- `data` [data:optional]: input data
- `nonce` [number]: account nonce
3. method signature [string:optional]
- The method signature, if present, is to aid decoding the calldata. Should consist of `methodname(paramtype,...)`, e.g. `transfer(uint256,address)`. The signer may use this data to parse the supplied calldata, and show the user. The data, however, is considered totally untrusted, and reliability is not expected.

## UI API
These methods needs to be implemented by a UI listener.
By starting the signer with the switch `--stdio-ui-test`, the signer will invoke all known methods, and expect the UI to respond with
denials. This can be used during development to ensure that the API is (at least somewhat) correctly implemented.
See `pythonsigner`, which can be invoked via `python3 pythonsigner.py test` to perform the 'denial-handshake-test'.
All methods in this API uses object-based parameters, so that there can be no mixups of parameters: each piece of data is accessed by key.
See the [ui api changelog](intapi_changelog.md) for information about changes to this API.
OBS! A slight deviation from `json` standard is in place: every request and response should be confined to a single line.
Whereas the `json` specification allows for linebreaks, linebreaks __should not__ be used in this communication channel, to make
things simpler for both parties.

}
}
]
}
```
### ApproveSignData
#### Sample call
```json
{
"jsonrpc": "2.0",
"id": 4,
"method": "ApproveSignData",
"params": [
{
"address": "0x123409812340981234098123409812deadbeef42",
"raw_data": "0x01020304",

"meta": {
"remote": "signer binary",
"local": "main",
"scheme": "in-proc"
}
}
]
}
```
### ShowInfo
The UI should show the info to the user. Does not expect response.
#### Sample call
```json
{
"jsonrpc": "2.0",
"id": 9,
"method": "ShowInfo",
"params": [
{
"text": "Tests completed"
}
]
}
```
### ShowError
The UI should show the info to the user. Does not expect response.
```json
{
"jsonrpc": "2.0",
"id": 2,
"method": "ShowError",
"params": [
{
"text": "Testing 'ShowError'"
}
]
}
```
### OnApproved
`OnApprovedTx` is called when a transaction has been approved and signed. The call contains the return value that will be sent to the external caller. The return value from this method is ignored - the reason for having this callback is to allow the ruleset to keep track of approved transactions.
When implementing rate-limited rules, this callback should be used.
TLDR; Use this method to keep track of signed transactions, instead of using the data in `ApproveTx`.
### OnSignerStartup
This method provide the UI with information about what API version the signer uses (both internal and external) aswell as build-info and external api,
in k/v-form.
Example call:
```json
{
"jsonrpc": "2.0",
"id": 1,
"method": "OnSignerStartup",
"params": [
{
"info": {
"extapi_http": "http://localhost:8550",
"extapi_ipc": null,
"extapi_version": "2.0.0",
"intapi_version": "1.2.0"
}
}
]
}
```
### Rules for UI apis
A UI should conform to the following rules.
* A UI MUST NOT load any external resources that were not embedded/part of the UI package.
* For example, not load icons, stylesheets from the internet
* Not load files from the filesystem, unless they reside in the same local directory (e.g. config files)
* A Graphical UI MUST show the blocky-identicon for ethereum addresses.
* A UI MUST warn display approproate warning if the destination-account is formatted with invalid checksum.
* A UI MUST NOT open any ports or services
* The signer opens the public port
* A UI SHOULD verify the permissions on the signer binary, and refuse to execute or warn if permissions allow non-user write.
* A UI SHOULD inform the user about the `SHA256` or `MD5` hash of the binary being executed
* A UI SHOULD NOT maintain a secondary storage of data, e.g. list of accounts
* The signer provides accounts
* A UI SHOULD, to the best extent possible, use static linking / bundling, so that required libraries are bundled
along with the UI.
### UI Implementations
There are a couple of implementation for a UI. We'll try to keep this list up to date.

# Setting up Clef
This document describes how Clef can be used in a more secure manner than executing it from your everyday laptop,
in order to ensure that the keys remain safe in the event that your computer should get compromised.
## Qubes OS
### Background
The Qubes operating system is based around virtual machines (qubes), where a set of virtual machines are configured, typically for
different purposes such as:
- personal
- Your personal email, browsing etc
- work
- Work email etc
- vault
- a VM without network access, where gpg-keys and/or keepass credentials are stored.
A couple of dedicated virtual machines handle externalities:
- sys-net provides networking to all other (network-enabled) machines
- sys-firewall handles firewall rules
- sys-usb handles USB devices, and can map usb-devices to certain qubes.
The goal of this document is to describe how we can set up clef to provide secure transaction
signing from a `vault` vm, to another networked qube which runs Dapps.
### Setup
There are two ways that this can be achieved: integrated via Qubes or integrated via networking.
#### 1. Qubes Integrated
Qubes provdes a facility for inter-qubes communication via `qrexec`. A qube can request to make a cross-qube RPC request
to another qube. The OS then asks the user if the call is permitted.
![Example](qubes/qrexec-example.png)
A policy-file can be created to allow such interaction. On the `target` domain, a service is invoked which can read the
`stdin` from the `client` qube.
This is how [Split GPG](https://www.qubes-os.org/doc/split-gpg/) is implemented. We can set up Clef the same way:
##### Server
![Clef via qrexec](qubes/clef_qubes_qrexec.png)
On the `target` qubes, we need to define the rpc service.
[qubes.Clefsign](qubes/qubes.Clefsign):
```bash
#!/bin/bash
SIGNER_BIN="/home/user/tools/clef/clef"
SIGNER_CMD="/home/user/tools/gtksigner/gtkui.py -s $SIGNER_BIN"
# Start clef if not already started
if [ ! -S /home/user/.clef/clef.ipc ]; then
$SIGNER_CMD &
sleep 1
fi
# Should be started by now
if [ -S /home/user/.clef/clef.ipc ]; then
# Post incoming request to HTTP channel
curl -H "Content-Type: application/json" -X POST -d @- http://localhost:8550 2>/dev/null
fi
```
This RPC service is not complete (see notes about HTTP headers below), but works as a proof-of-concept.
It will forward the data received on `stdin` (forwarded by the OS) to Clef's HTTP channel.
It would have been possible to send data directly to the `/home/user/.clef/.clef.ipc`
socket via e.g `nc -U /home/user/.clef/clef.ipc`, but the reason for sending the request
data over `HTTP` instead of `IPC` is that we want the ability to forward `HTTP` headers.
To enable the service:
``` bash
sudo cp qubes.Clefsign /etc/qubes-rpc/
sudo chmod +x /etc/qubes-rpc/ qubes.Clefsign
```
This setup uses [gtksigner](https://github.com/holiman/gtksigner), which is a very minimal GTK-based UI that works well
with minimal requirements.
##### Client
On the `client` qube, we need to create a listener which will receive the request from the Dapp, and proxy it.
[qubes-client.py](qubes/client/qubes-client.py):
```python
"""
This implements a dispatcher which listens to localhost:8550, and proxies
requests via qrexec to the service qubes.EthSign on a target domain
"""
import http.server
import socketserver,subprocess
PORT=8550
TARGET_DOMAIN= 'debian-work'
class Dispatcher(http.server.BaseHTTPRequestHandler):
def do_POST(self):
post_data = self.rfile.read(int(self.headers['Content-Length']))
p = subprocess.Popen(['/usr/bin/qrexec-client-vm',TARGET_DOMAIN,'qubes.Clefsign'],stdin=subprocess.PIPE, stdout=subprocess.PIPE)
output = p.communicate(post_data)[0]
self.wfile.write(output)
with socketserver.TCPServer(("",PORT), Dispatcher) as httpd:
print("Serving at port", PORT)
httpd.serve_forever()
```
#### Testing
To test the flow, if we have set up `debian-work` as the `target`, we can do
```bash
$ cat newaccnt.json
{ "id": 0, "jsonrpc": "2.0","method": "account_new","params": []}
$ cat newaccnt.json| qrexec-client-vm debian-work qubes.Clefsign
```
This should pop up first a dialog to allow the IPC call:
![one](qubes/qubes_newaccount-1.png)
Followed by a GTK-dialog to approve the operation
![two](qubes/qubes_newaccount-2.png)
To test the full flow, we use the client wrapper. Start it on the `client` qube:
```
[user@work qubes]$ python3 qubes-client.py
```
Make the request over http (`client` qube):
```
[user@work clef]$ cat newaccnt.json | curl -X POST -d @- http://localhost:8550
```
And it should show the same popups again.
##### Pros and cons
The benefits of this setup are:
- This is the qubes-os intended model for inter-qube communication,
- and thus benefits from qubes-os dialogs and policies for user approval
However, it comes with a couple of drawbacks:
- The `qubes-gpg-client` must forward the http request via RPC to the `target` qube. When doing so, the proxy
will either drop important headers, or replace them.
- The `Host` header is most likely `localhost`
- The `Origin` header must be forwarded
- Information about the remote ip must be added as a `X-Forwarded-For`. However, Clef cannot always trust an `XFF` header,
since malicious clients may lie about `XFF` in order to fool the http server into believing it comes from another address.
- Even with a policy in place to allow rpc-calls between `caller` and `target`, there will be several popups:
- One qubes-specific where the user specifies the `target` vm
- One clef-specific to approve the transaction
#### 2. Network integrated
The second way to set up Clef on a qubes system is to allow networking, and have Clef listen to a port which is accessible
form other qubes.
![Clef via http](qubes/clef_qubes_http.png)
## USBArmory
The [USB armory](https://inversepath.com/usbarmory) is an open source hardware design with an 800 Mhz ARM processor. It is a pocket-size
computer. When inserted into a laptop, it identifies itself as a USB network interface, basically adding another network
to your computer. Over this new network interface, you can SSH into the device.
Running Clef off a USB armory means that you can use the armory as a very versatile offline computer, which only
ever connects to a local network between your computer and the device itself.
Needless to say, the while this model should be fairly secure against remote attacks, an attacker with physical access
to the USB Armory would trivially be able to extract the contents of the device filesystem.

### Changelog for external API
#### 4.0.0
* The external `account_Ecrecover`-method was removed.
* The external `account_Import`-method was removed.
#### 3.0.0
* The external `account_List`-method was changed to not expose `url`, which contained info about the local filesystem. It now returns only a list of addresses.
#### 2.0.0
* Commit `73abaf04b1372fa4c43201fb1b8019fe6b0a6f8d`, move `from` into `transaction` object in `signTransaction`. This
makes the `accounts_signTransaction` identical to the old `eth_signTransaction`.
#### 1.0.0
Initial release.
### Versioning
The API uses [semantic versioning](https://semver.org/).
TLDR; Given a version number MAJOR.MINOR.PATCH, increment the:
* MAJOR version when you make incompatible API changes,
* MINOR version when you add functionality in a backwards-compatible manner, and
* PATCH version when you make backwards-compatible bug fixes.
Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.

### 3.0.0
* Make use of `OnInputRequired(info UserInputRequest)` for obtaining master password during startup
### 2.1.0
* Add `OnInputRequired(info UserInputRequest)` to internal API. This method is used when Clef needs user input, e.g. passwords.
The following structures are used:
```golang
UserInputRequest struct {
Prompt string `json:"prompt"`
Title string `json:"title"`
IsPassword bool `json:"isPassword"`
}
UserInputResponse struct {
Text string `json:"text"`
}
### 2.0.0
* Modify how `call_info` on a transaction is conveyed. New format:
```

# Rules
The `signer` binary contains a ruleset engine, implemented with [OttoVM](https://github.com/robertkrimen/otto)
It enables usecases like the following:
* I want to auto-approve transactions with contract `CasinoDapp`, with up to `0.05 ether` in value to maximum `1 ether` per 24h period
* I want to auto-approve transaction to contract `EthAlarmClock` with `data`=`0xdeadbeef`, if `value=0`, `gas < 44k` and `gasPrice < 40Gwei`
The two main features that are required for this to work well are;
1. Rule Implementation: how to create, manage and interpret rules in a flexible but secure manner
2. Credential managements and credentials; how to provide auto-unlock without exposing keys unnecessarily.
The section below deals with both of them
## Rule Implementation
A ruleset file is implemented as a `js` file. Under the hood, the ruleset-engine is a `SignerUI`, implementing the same methods as the `json-rpc` methods
defined in the UI protocol. Example:
```javascript
function asBig(str){
if(str.slice(0,2) == "0x"){ return new BigNumber(str.slice(2),16)}
return new BigNumber(str)
}
// Approve transactions to a certain contract if value is below a certain limit
function ApproveTx(req){
var limit = big.Newint("0xb1a2bc2ec50000")
var value = asBig(req.transaction.value);
if(req.transaction.to.toLowerCase()=="0xae967917c465db8578ca9024c205720b1a3651a9")
&& value.lt(limit) ){
return "Approve"
}
// If we return "Reject", it will be rejected.
// By not returning anything, it will be passed to the next UI, for manual processing
}
//Approve listings if request made from IPC
function ApproveListing(req){
if (req.metadata.scheme == "ipc"){ return "Approve"}
}
```
Whenever the external API is called (and the ruleset is enabled), the `signer` calls the UI, which is an instance of a ruleset-engine. The ruleset-engine
invokes the corresponding method. In doing so, there are three possible outcomes:
1. JS returns "Approve"
* Auto-approve request
2. JS returns "Reject"
* Auto-reject request
3. Error occurs, or something else is returned
* Pass on to `next` ui: the regular UI channel.
A more advanced example can be found below, "Example 1: ruleset for a rate-limited window", using `storage` to `Put` and `Get` `string`s by key.
* At the time of writing, storage only exists as an ephemeral unencrypted implementation, to be used during testing.
### Things to note
The Otto vm has a few [caveats](https://github.com/robertkrimen/otto):
* "use strict" will parse, but does nothing.
* The regular expression engine (re2/regexp) is not fully compatible with the ECMA5 specification.
* Otto targets ES5. ES6 features (eg: Typed Arrays) are not supported.
Additionally, a few more have been added
* The rule execution cannot load external javascript files.
* The only preloaded libary is [`bignumber.js`](https://github.com/MikeMcl/bignumber.js) version `2.0.3`. This one is fairly old, and is not aligned with the documentation at the github repository.
* Each invocation is made in a fresh virtual machine. This means that you cannot store data in global variables between invocations. This is a deliberate choice -- if you want to store data, use the disk-backed `storage`, since rules should not rely on ephemeral data.
* Javascript API parameters are _always_ an object. This is also a design choice, to ensure that parameters are accessed by _key_ and not by order. This is to prevent mistakes due to missing parameters or parameter changes.
* The JS engine has access to `storage` and `console`.
#### Security considerations
##### Security of ruleset
Some security precautions can be made, such as:
* Never load `ruleset.js` unless the file is `readonly` (`r-??-??-?`). If the user wishes to modify the ruleset, he must make it writeable and then set back to readonly.
* This is to prevent attacks where files are dropped on the users disk.
* Since we're going to have to have some form of secure storage (not defined in this section), we could also store the `sha3` of the `ruleset.js` file in there.
* If the user wishes to modify the ruleset, he'd then have to perform e.g. `signer --attest /path/to/ruleset --credential <creds>`
##### Security of implementation
The drawbacks of this very flexible solution is that the `signer` needs to contain a javascript engine. This is pretty simple to implement, since it's already
implemented for `geth`. There are no known security vulnerabilities in, nor have we had any security-problems with it so far.
The javascript engine would be an added attack surface; but if the validation of `rulesets` is made good (with hash-based attestation), the actual javascript cannot be considered
an attack surface -- if an attacker can control the ruleset, a much simpler attack would be to implement an "always-approve" rule instead of exploiting the js vm. The only benefit
to be gained from attacking the actual `signer` process from the `js` side would be if it could somehow extract cryptographic keys from memory.
##### Security in usability
Javascript is flexible, but also easy to get wrong, especially when users assume that `js` can handle large integers natively. Typical errors
include trying to multiply `gasCost` with `gas` without using `bigint`:s.
It's unclear whether any other DSL could be more secure; since there's always the possibility of erroneously implementing a rule.
## Credential management
The ability to auto-approve transaction means that the signer needs to have necessary credentials to decrypt keyfiles. These passwords are hereafter called `ksp` (keystore pass).
### Example implementation
Upon startup of the signer, the signer is given a switch: `--seed <path/to/masterseed>`
The `seed` contains a blob of bytes, which is the master seed for the `signer`.
The `signer` uses the `seed` to:
* Generate the `path` where the settings are stored.
* `./settings/1df094eb-c2b1-4689-90dd-790046d38025/vault.dat`
* `./settings/1df094eb-c2b1-4689-90dd-790046d38025/rules.js`
* Generate the encryption password for `vault.dat`.
The `vault.dat` would be an encrypted container storing the following information:
* `ksp` entries
* `sha256` hash of `rules.js`
* Information about pair:ed callers (not yet specified)
### Security considerations
This would leave it up to the user to ensure that the `path/to/masterseed` is handled in a secure way. It's difficult to get around this, although one could
imagine leveraging OS-level keychains where supported. The setup is however in general similar to how ssh-keys are stored in `.ssh/`.
# Implementation status
This is now implemented (with ephemeral non-encrypted storage for now, so not yet enabled).
## Example 1: ruleset for a rate-limited window
```javascript
function big(str){
if(str.slice(0,2) == "0x"){ return new BigNumber(str.slice(2),16)}
return new BigNumber(str)
}
// Time window: 1 week
var window = 1000* 3600*24*7;
// Limit : 1 ether
var limit = new BigNumber("1e18");
function isLimitOk(transaction){
var value = big(transaction.value)
// Start of our window function
var windowstart = new Date().getTime() - window;
var txs = [];
var stored = storage.Get('txs');
if(stored != ""){
txs = JSON.parse(stored)
}
// First, remove all that have passed out of the time-window
var newtxs = txs.filter(function(tx){return tx.tstamp > windowstart});
console.log(txs, newtxs.length);
// Secondly, aggregate the current sum
sum = new BigNumber(0)
sum = newtxs.reduce(function(agg, tx){ return big(tx.value).plus(agg)}, sum);
console.log("ApproveTx > Sum so far", sum);
console.log("ApproveTx > Requested", value.toNumber());
// Would we exceed weekly limit ?
return sum.plus(value).lt(limit)
}
function ApproveTx(r){
if (isLimitOk(r.transaction)){
return "Approve"
}
return "Nope"
}
/**
* OnApprovedTx(str) is called when a transaction has been approved and signed. The parameter
* 'response_str' contains the return value that will be sent to the external caller.
* The return value from this method is ignore - the reason for having this callback is to allow the
* ruleset to keep track of approved transactions.
*
* When implementing rate-limited rules, this callback should be used.
* If a rule responds with neither 'Approve' nor 'Reject' - the tx goes to manual processing. If the user
* then accepts the transaction, this method will be called.
*
* TLDR; Use this method to keep track of signed transactions, instead of using the data in ApproveTx.
*/
function OnApprovedTx(resp){
var value = big(resp.tx.value)
var txs = []
// Load stored transactions
var stored = storage.Get('txs');
if(stored != ""){
txs = JSON.parse(stored)
}
// Add this to the storage
txs.push({tstamp: new Date().getTime(), value: value});
storage.Put("txs", JSON.stringify(txs));
}
```
## Example 2: allow destination
```javascript
function ApproveTx(r){
if(r.transaction.from.toLowerCase()=="0x0000000000000000000000000000000000001337"){ return "Approve"}
if(r.transaction.from.toLowerCase()=="0x000000000000000000000000000000000000dead"){ return "Reject"}
// Otherwise goes to manual processing
}
```
## Example 3: Allow listing
```javascript
function ApproveListing(){
return "Approve"
}
```
