Yes. IDEA is Godzilla, CAST5 is Moth-Ra and 3DES is MechaGodzilla. They all excel at stomping cities flat and terrorizing inhabitants. All that people in Tokyo need to know about them is "when you see them coming, run for the hills." The above answer is tongue in cheek, but there's a lot of accuracy in it. Unless you're a professional cryptographer, the various cryptanalytic analyses of the OpenPGP cipher suite are going to be pretty much meaningless and unhelpful. For 99% of other people--myself included--it really reduces down to "they are all believed resistant against all known forms of cryptanalysis, and are impractical to brute force." If you really want to go down this road, it would help if you clarified your question a lot. What sort of comparisons? How many operations are involved in an encryption cycle? Decryption cycle? How much processing is involved in key setup? Relative size of code? Hardware requirements? Efficiency? Best known cryptanalytic attacks? Etc., etc. Your question, as phrased, is far too general to give any sort of meaningful answer except "as far as the layman is concerned, they're pretty much identical". _______________________________________________ Gnupg-users mailing list [email protected] http://lists.gnupg.org/mailman/listinfo/gnupg-users
