Importing GnuPG private key into PGP?

[Todd L. Brooks]

By default, I think GnuPG encrypts your secret key using the Blowfish
symmetric algorithm. PGP will only understand 3DES, CAST5, or IDEA
symmetric algorithms. The following method works for me:

$ gpg --s2k-cipher-algo=CAST5 --s2k-digest-algo=SHA1 --compress-algo=1 \
 --edit-key username

then use passwd to change the password (just change it to the same thing,
but it will encrypt the key with CAST5 this time).

Now you can export it and PGP should be able to handle it. -Todd
