 -u,--usage <arg>          Usage, one of: enc, sig (optional)
 -a,--algorithm <arg>      Algorithm (optional)
 -i,--id <arg>             Key ID (optional), one will be generated if not
                           defined
 -g,--idGenerator <arg>    Key ID generation method (optional). Can be one
                           of: date, timestamp, sha256, sha1, none. If
                           omitted, generator method defaults to
                           'timestamp'.
 -I,--noGenerateId         <deprecated> Don't generate a Key ID.

 -S,--keySet               Wrap the generated key in a KeySet
 -o,--output <arg>         Write output to file. Will append to existing

 -P,--pubKeyOutput <arg>   Write public key to separate file. Will append
                           to existing KeySet if -S is used. Key material
                           will not be displayed to console. '-o/--output'
                           must be declared as well.
