I know it uses RSA/DSA to create keys, but does it use that same algorithm for the actual cipher?


1 Answer 1


According to How PGP Works it uses a hybrid approach that generates a secret key for symmetric encryption. The wikipedia page for GPG then indicates that CAST5, Camellia, Triple DES, AES, Blowfish, and Twofish are the supported ciphers.
