Brute forcing an algorithm suggests that you are not attacking a weakness or known flaw in the algorithm but rather just running through the keyspace trying to recover the plaintext. In that case, whichever allows you to use the most bits is what you want. IIRC, there aren't any good known attacks against Blowfish, AES, or Twofish so the *RIGHT* algorithm is whatever works best for your application. Also, your encrypt-decrypt-encrypt choices may be "more" secure from a pure brute force perspective but the marginal security they add doesn't negate the difficulty of key management. You should look into Bruce Schneier's book, "Applied Cryptography" (ISBN: 0471117099) for an excellent treatment on the subject. Brandon Enright Bipin Gautam wrote:
hello list, Which Algorithm in the list is hard hard (more resource/computation consuming) to brute-force... (in order?) considering all other factor 'ALMOST' similar? views? ---------- Blowfish AES Twofish AES-BLOWFISH Serpant CAST5 AES-Twofish Serpant-AES AES-BLOWFISH-SERPANT Twofish-SERPANT Triple DES AES-Twofish-Serpant Serpant-Twofish-AES * Feel free to discuss algorithms NOT LISTED here and also the ones used by FILE-COMPRESSION utilities ??? Even if you know a geleral statistic abt. a few of these or any experience/info please share. I'm trying to draw a nice statistic BUT couldn't find it elsewhere. -- Bipin Gautam http://bipin.tk
