This right here is one of the great things about OpenPGP: cipher
choices are handled for you automatically.  Each user specifies what
ciphers they can handle in whatever order they like (like AES?  List
it first!) and the program figures out the best choice give the

You can add cipher preferences to an PGP2-style key, but PGP2 can't
handle it.  You can only use a key with preferences in more recent
