Sure. As long as the tool understand the OpenPGP protocol. > For example, if one knows that CAST5-CFB, ZIP, and salted-and-iterated > S2K was used (as well as the value of the salt and number of > iterations), might one be able to decrypt the message using OpenSSL > and other common utilities? I suspect yes, as the encryption and Yes. Many years ago there used to be a toolset with reference implementation based on OpenSSL. IIRC, it was also available as a printed book.
