Is AES-256 weaker than 192 and 128 bit versions?AES is an algorithm which is split into several internal rounds, and each round needs a specific 128-bit subkey (and an extra subkey is needed at the end). In an ideal world, the 11/13/15 subkeys would be generated from a strong, cryptographically secure PRNG, itself seeded with "the" key. However, this world is not ideal, and the subkeys are generated through a process called the key schedule, wh
