So the algorithms include the number of rounds? I thought that it would only describe the math process and that it would be independent of the number of rounds (so long as you meed Rijndael's "minimum" - which is what the current number of rounds is set/default as).
I did not know that. Hmmm....thanks. Does this mean that a AES-192-CBC is less secure than an AES-256-CBC because of the key length and the number of rounds associated with that; or am I understanding that wrong - that the number of rounds has less-so to do with the security of the algorithm compared to the key length?
