    The answer(s) to this question stating that, regarding MCRYPT_RIJNDAEL_128 and MCRYPT_RIJNDAEL_256, "The number 128 or 256 is the key length" - this is incorrect. These numbers refer to the blocksize, not the keylength. However, both implementations (using a block size of 128 or 256 bits) can accept keys of 128 or 256 bits.
