This raises a point about compatability of GPG keys with PGP 8.x. The default
compression preferences in GPG are Z2 Z1 (ZLIB ZIP) and decompression
failures with GPG-encrypted messages were reported by PGP 8.0.3 users in a
recent thread on the PGP-Basics list.
PGP keys have no compression (or hash) preferences as far as I can see by
importing a PGP key and doing gpg --pref, so it seems GPG uses ZLIB even if
PGP 8 can't handle it, and apparently has no way of finding from the PGP key
that it shouldn't.
