Re: specifying the number of rounds that I would like to use with AES-192-CBC
Are their pre-compiled programs already where I could be able to see/play with the effects of changing the number of rounds using the Rijndael algorithm?

Re: specifying the number of rounds that I would like to use with AES-192-CBC
Is AES-CBC decryption independent of the number of rounds that was used during the encryption process? 0.o?

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

Re: specifying the number of rounds that I would like to use with AES-192-CBC
AES/Rijndahl AES has fixed number of rounds and other parameters. Rijndahl allows you to specify the algorithm parameters including number of rounds. Steven J.

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

I don't know the interfaces to OpenSSL, but AES-192 specifies the number of rounds.
