I'm looking at this from a GPGME perspective. If I tell GnuPG to
symmetrically encrypt a file, I'd like for GnuPG to tell me what
algorithm was used so that I can tell the user (in case they let it
default to the s2k cipher algorithm, which the average user probably
doesn't know off hand). Maybe there's no way to do it?
At any rate this probably won't matter if I can specify the cipher
algorithm.

A quick test will show that you are correct, but the documentation says
that the default is Blowfish.
