If they are compressing before they PGP, then they could be using
anything. It's not really a PGP or GnuPG question. There are many
different compression programs out there, using different algorithms,
and a 10x compression is not unheard of.
If they are compressing within PGP, then it's ZIP compression, as
that's the only compression algorithm that PGP supports. GnuPG
supports it as well, so anything your client could do in PGP, you
could do in GnuPG.
