==========================

was twofish originally implemented in openPGP as a 128 bit cipher?  the
current implementation is 256 bit... or did you mean to say that blowfish
was the first freely available 128 bit block cipher?

==========================

i can't figure out why NIST/NSA/ANSI etc are taking so long to formalize
the larger versions of DSS/DSA. i guess in the meantime, one can use
RSA-3072 with SHA-256 (if they're using a bleeding-edge version of gpg).
