ethkey
ethkey is a simple command-line tool for working with Ethereum keyfiles.
Usage

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.
