Ethereum keys generator.
[Documentation](http://ethcore.github.io/ethkey/ethkey/index.html)
### Usage
```
Ethereum keys generator.
Copyright 2016 Ethcore (UK) Limited
Usage:
ethkey info <secret> [options]
ethkey generate random [options]
ethkey generate prefix <prefix> <iterations> [options]
ethkey generate brain <seed> [options]
ethkey sign <secret> <message>
ethkey verify <public> <signature> <message>
ethkey [-h | --help]
Options:
-h, --help Display this message and exit.
-s, --secret Display only the secret.
-p, --public Display only the public.
-a, --address Display only the address.
Commands:
info Display public and address of the secret.
generate Generates new ethereum key.

Ethereum key management.
[Documentation](http://ethcore.github.io/ethstore/ethstore/index.html)
### Usage
```
Ethereum key management.
Copyright 2016 Ethcore (UK) Limited
Usage:
ethstore insert <secret> <password> [--dir DIR]
ethstore change-pwd <address> <old-pwd> <new-pwd> [--dir DIR]
ethstore list [--dir DIR]
ethstore import [--src DIR] [--dir DIR]
ethstore remove <address> <password> [--dir DIR]
ethstore sign <address> <password> <message> [--dir DIR]
ethstore [-h | --help]
Options:
-h, --help Display this message and exit.
--dir DIR Specify the secret store directory. It may be either
parity, parity-test, geth, geth-test
or a path [default: parity].
--src DIR Specify import source. It may be either
parity, parity-test, get, geth-test
or a path [default: geth].
Commands:
insert Save account with password.
change-pwd Change account password.
list List accounts.
import Import accounts from src.
remove Remove account.
sign Sign message.
```
### Examples
#### `insert <secret> <password> [--dir DIR]`
