Re: specifying the number of rounds that I would like to use with AES-192-CBC

2013-03-17 Thread Ewen Chan
Curious question - still more about AES and CBC and openssl:

Does the number of rounds during the encryption phase of it have to
match the number of rounds during the decryption phase of it, or does
it not matter? (i.e. the rounds count really only matters during the
encryption-only phase, and for decryption; it is independent of it)?

 So is the number of rounds set by Rijndahl or the AES spec? I'm
 confused.

 And is the number of rounds hard-coded into the OpenSSL source; or is
 it embedded somewhere else?

 There's a file that I want to encrypt using AES-192-CBC but with 19
 rounds rather than the default 12-rounds.

 Is there a way for me to specify the number of rounds that I would
 like to use with the AES-192-CBC? (and override the algorithm
 defaults)?

 Is that something that I can within the openssl command itself (to
 encrypt a file) or is the process much more involved than that? And
 requires programming/scripting?
