A simple utility class that generates a public/secret keyring containing a DSA signing key and an El Gamal key for encryption.

usage: DSAElGamalKeyRingGenerator [-a] identity passPhrase

Where identity is the name to be associated with the public key. The keys are placed in the files pub.[asc|bpg] and secret.[asc|bpg].
