following are my
# Options for GnuPG
which work fine with pgp:

# interop with PGP 5 users.  for OpenPGP compliance remove this option.
force-v3-sigs
#compress-algo 2=default 1=pgp
compress-algo 1
# pgp uses idea, rsa, both patented in the usa.  for gpg there is elgamal
# for encryption and dsa for compact signatures.  the symmetric algos are:
# Cipher: IDEA, 3DES, CAST5, BLOWFISH, TWOFISH
#cipher-algo <name> pgp-compatible={3des cast5 !(blow|two)fish}
cipher-algo cast5
#digest-algo <name> {md5 ripemd160 sha1}
digest-algo sha1
#s2k-cipher-algo <name>, which is the string-to-key cipher used for seckeys
s2k-cipher-algo cast5
disable-cipher-algo blowfish
# defaults:  dsa/signing, elgamal/encryption
disable-pubkey-algo ELG
load-extension idea
load-extension rsa
