### Integration Test
In order to run the integration tests, you will need to run them against a real node. At the moment the integration tests require [Geth v1.7.2](https://ethereum.github.io/go-ethereum/downloads/) as they depend on the `--dev` mode, which changed in v1.7.3

processing the entire history of the Ethereum network, which is very CPU intensive.
* Bump the memory allowance of the database to 512MB (`--cache=512`), which can help significantly in
sync times especially for HDD users. This flag is optional and you can set it as high or as low as

### Full node on the Rinkeby test network
The above test network is a cross client one based on the ethash proof-of-work consensus algorithm. As such, it has certain extra overhead and is more susceptible to reorganization attacks due to the network's low difficulty / security. Go Ethereum also supports connecting to a proof-of-authority based test network called [*Rinkeby*](https://www.rinkeby.io) (operated by members of the community). This network is lighter, more secure, but is only supported by go-ethereum.

ethkey
======
ethkey is a simple command-line tool for working with Ethereum keyfiles.
# Usage
### `ethkey generate`
Generate a new keyfile.
If you want to use an existing private key to use in the keyfile, it can be
specified by setting `--privatekey` with the location of the file containing the
private key.
### `ethkey inspect <keyfile>`
Print various information about the keyfile.
Private key information can be printed by using the `--private` flag;
make sure to use this feature with great caution!
### `ethkey sign <keyfile> <message/file>`
Sign the message with a keyfile.
It is possible to refer to a file containing the message.
### `ethkey verify <address> <signature> <message/file>`
Verify the signature of the message.
It is possible to refer to a file containing the message.
## Passphrases
For every command that uses a keyfile, you will be prompted to provide the
passphrase for decrypting the keyfile. To avoid this message, it is possible
to pass the passphrase by using the `--passphrase` flag pointing to a file that
contains the passphrase.
