After `dep` finishes, dependencies should be installed within your `GOPATH` at the versions specified in `Gopkg.toml`.
Because we are working with a modified version of the go-ethereum accounts/abi package, after running `dep ensure` you will need to run `git checkout vendor/github/ethereum/go-ethereum/accounts/abi` to checkout the modified dependency.
Lastly, ensure that `GOPATH` is defined in your shell. If necessary, `GOPATH` can be set in `~/.bashrc` or `~/.bash_profile`, depending upon your system. It can be additionally helpful to add `$GOPATH/bin` to your shell's `$PATH`.

|:----------:|-------------|
| **`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. |

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.

| `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`). |

## UI Client interface
These data types are defined in the channel between clef and the UI
### SignDataRequest
SignDataRequest contains information about a pending request to sign some data. The data to be signed can be of various types, defined by content-type. Clef has done most of the work in canonicalizing and making sense of the data, and it's up to the UI to presentthe user with the contents of the `message`
Example:
```json
{
"content_type": "text/plain",
"address": "0xDEADbEeF000000000000000000000000DeaDbeEf",
"raw_data": "GUV0aGVyZXVtIFNpZ25lZCBNZXNzYWdlOgoxMWhlbGxvIHdvcmxk",
"message": [
{
"name": "message",
"value": "\u0019Ethereum Signed Message:\n11hello world",
"type": "text/plain"
}
],
"hash": "0xd9eba16ed0ecae432b71fe008c98cc872bb4cc214d3220a36f365326cf807d68",
"meta": {
"remote": "localhost:9999",
"local": "localhost:8545",
"scheme": "http",
"User-Agent": "Firefox 3.2",
"Origin": "www.malicious.ru"
}
}
```
### SignDataResponse - approve
Response to SignDataRequest
Example:
```json
{
"approved": true
}
```
### SignDataResponse - deny
Response to SignDataRequest
Example:
```json
{
"approved": false
}
```
### SignTxRequest
SignTxRequest contains information about a pending request to sign a transaction. Aside from the transaction itself, there is also a `call_info`-struct. That struct contains messages of various types, that the user should be informed of.
As in any request, it's important to consider that the `meta` info also contains untrusted data.
The `transaction` (on input into clef) can have either `data` or `input` -- if both are set, they must be identical, otherwise an error is generated. However, Clef will always use `data` when passing this struct on (if Clef does otherwise, please file a ticket)
Example:
```json
{
"transaction": {
"from": "0xDEADbEeF000000000000000000000000DeaDbeEf",
"to": null,
"gas": "0x3e8",
"gasPrice": "0x5",
"value": "0x6",
"nonce": "0x1",
"data": "0x01020304"
},
"call_info": [
{
"type": "Warning",
"message": "Something looks odd, show this message as a warning"
},
{
"type": "Info",
"message": "User should see this aswell"
}
],
"meta": {
"remote": "localhost:9999",
"local": "localhost:8545",
"scheme": "http",
"User-Agent": "Firefox 3.2",
"Origin": "www.malicious.ru"
}
}
```
### SignTxResponse - approve
Response to request to sign a transaction. This response needs to contain the `transaction`, because the UI is free to make modifications to the transaction.
Example:
```json
{
"transaction": {
"from": "0xDEADbEeF000000000000000000000000DeaDbeEf",
"to": null,
"gas": "0x3e8",
"gasPrice": "0x5",
"value": "0x6",
"nonce": "0x4",
"data": "0x04030201"
},
"approved": true
}
```
### SignTxResponse - deny
Response to SignTxRequest. When denying a request, there's no need to provide the transaction in return
Example:
```json
{
"transaction": {
"from": "0x",
"to": null,
"gas": "0x0",
"gasPrice": "0x0",
"value": "0x0",
"nonce": "0x0",
"data": null
},
"approved": false
}
```
### OnApproved - SignTransactionResult
SignTransactionResult is used in the call `clef` -> `OnApprovedTx(result)`
This occurs _after_ successful completion of the entire signing procedure, but right before the signed transaction is passed to the external caller. This method (and data) can be used by the UI to signal to the user that the transaction was signed, but it is primarily useful for ruleset implementations.
A ruleset that implements a rate limitation needs to know what transactions are sent out to the external interface. By hooking into this methods, the ruleset can maintain track of that count.
**OBS:** Note that if an attacker can restore your `clef` data to a previous point in time (e.g through a backup), the attacker can reset such windows, even if he/she is unable to decrypt the content.
The `OnApproved` method cannot be responded to, it's purely informative
Example:
```json
{
"raw": "0xf85d640101948a8eafb1cf62bfbeb1741769dae1a9dd47996192018026a0716bd90515acb1e68e5ac5867aa11a1e65399c3349d479f5fb698554ebc6f293a04e8a4ebfff434e971e0ef12c5bf3a881b06fd04fc3f8b8a7291fb67a26a1d4ed",
"tx": {
"nonce": "0x64",
"gasPrice": "0x1",
"gas": "0x1",
"to": "0x8a8eafb1cf62bfbeb1741769dae1a9dd47996192",
"value": "0x1",
"input": "0x",
"v": "0x26",
"r": "0x716bd90515acb1e68e5ac5867aa11a1e65399c3349d479f5fb698554ebc6f293",

"hash": "0x662f6d772692dd692f1b5e8baa77a9ff95bbd909362df3fc3d301aafebde5441"
}
}
```
### UserInputRequest
Sent when clef needs the user to provide data. If 'password' is true, the input field should be treated accordingly (echo-free)
Example:
```json
{
"prompt": "The question to ask the user",
"title": "The title here",
"isPassword": true
}
```
### UserInputResponse
Response to UserInputRequest
Example:
```json
{
"text": "The textual response from user"
}
```
### ListRequest
Sent when a request has been made to list addresses. The UI is provided with the full `account`s, including local directory names. Note: this information is not passed back to the external caller, who only sees the `address`es.
Example:
```json
{
"accounts": [
{
"address": "0xdeadbeef000000000000000000000000deadbeef",
"url": "keystore:///path/to/keyfile/a"
},
{
"address": "0x1111111122222222222233333333334444444444",
"url": "keystore:///path/to/keyfile/b"
}
],
"meta": {
"remote": "localhost:9999",
"local": "localhost:8545",
"scheme": "http",
"User-Agent": "Firefox 3.2",
"Origin": "www.malicious.ru"
}
}
```
### ListResponse
Response to list request. The response contains a list of all addresses to show to the caller. Note: the UI is free to respond with any address the caller, regardless of whether it exists or not
Example:
```json
{
"accounts": [
{
"address": "0x0000000000000000000000000000000000000000",
"url": ".. ignored .."
},
{
"address": "0xffffffffffffffffffffffffffffffffffffffff",
"url": ""
}
]
}
```

### Changelog for external API
### 6.0.0
* `New` was changed to deliver only an address, not the full `Account` data
* `Export` was moved from External API to the UI Server API
#### 5.0.0
* The external `account_EcRecover`-method was reimplemented.
* The external method `account_sign(address, data)` was replaced with `account_signData(contentType, address, data)`.
The addition of `contentType` makes it possible to use the method for different types of objects, such as:
* signing data with an intended validator (not yet implemented)
* signing clique headers,
* signing plain personal messages,
* The external method `account_signTypedData` implements [EIP-712](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-712.md) and makes it possible to sign typed data.
#### 4.0.0
* The external `account_Ecrecover`-method was removed.

### Changelog for internal API (ui-api)
### 6.0.0
Removed `password` from responses to operations which require them. This is for two reasons,
- Consistency between how rulesets operate and how manual processing works. A rule can `Approve` but require the actual password to be stored in the clef storage.
With this change, the same stored password can be used even if rulesets are not enabled, but storage is.
- It also removes the usability-shortcut that a UI might otherwise want to implement; remembering passwords. Since we now will not require the
password on every `Approve`, there's no need for the UI to cache it locally.
- In a future update, we'll likely add `clef_storePassword` to the internal API, so the user can store it via his UI (currently only CLI works).
Affected datatypes:
- `SignTxResponse`
- `SignDataResponse`
- `NewAccountResponse`
If `clef` requires a password, the `OnInputRequired` will be used to collect it.
### 5.0.0
Changed the namespace format to adhere to the legacy ethereum format: `name_methodName`. Changes:
* `ApproveTx` -> `ui_approveTx`
* `ApproveSignData` -> `ui_approveSignData`
* `ApproveExport` -> `removed`
* `ApproveImport` -> `removed`
* `ApproveListing` -> `ui_approveListing`
* `ApproveNewAccount` -> `ui_approveNewAccount`
* `ShowError` -> `ui_showError`
* `ShowInfo` -> `ui_showInfo`
* `OnApprovedTx` -> `ui_onApprovedTx`
* `OnSignerStartup` -> `ui_onSignerStartup`
* `OnInputRequired` -> `ui_onInputRequired`
### 4.0.0
* Bidirectional communication implemented, so the UI can query `clef` via the stdin/stdout RPC channel. Methods implemented are:
- `clef_listWallets`
- `clef_listAccounts`
- `clef_listWallets`
- `clef_deriveAccount`
- `clef_importRawKey`
- `clef_openWallet`
- `clef_chainId`
- `clef_setChainId`
- `clef_export`
- `clef_import`
* The type `Account` was modified (the json-field `type` was removed), to consist of
```golang
type Account struct {
Address common.Address `json:"address"` // Ethereum account address derived from the key
URL URL `json:"url"` // Optional resource locator within a backend
}
```
### 3.2.0
* Make `ShowError`, `OnApprovedTx`, `OnSignerStartup` be json-rpc [notifications](https://www.jsonrpc.org/specification#notification):
> A Notification is a Request object without an "id" member. A Request object that is a Notification signifies the Client's lack of interest in the corresponding Response object, and as such no Response object needs to be returned to the client. The Server MUST NOT reply to a Notification, including those that are within a batch request.
>
> Notifications are not confirmable by definition, since they do not have a Response object to be returned. As such, the Client would not be aware of any errors (like e.g. "Invalid params","Internal error"
### 3.1.0
* Add `ContentType` `string` to `SignDataRequest` to accommodate the latest EIP-191 and EIP-712 implementations.
### 3.0.0
* Make use of `OnInputRequired(info UserInputRequest)` for obtaining master password during startup
