    This tool generates a CurveZMQ keypair, as two printable strings you can 
    use in configuration files or source code. The encoding uses Z85, which 
    is a base-85 format that is described in 0MQ RFC 32, and which has an 
    implementation in the z85_codec.h source used by this tool. The keypair
