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 <public> <signature> <message>
ethkey verify address <address> <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.
random Random generation.
prefix Random generation, but address must start with a prefix
brain Generate new key from string seed.
sign Sign message using secret.
verify Verify signer of the signature.
