* to save one include_once().

* If {@link Crypt_AES::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
* {@link Crypt_AES::setKey() setKey()}. ie. if the key is 128-bits, the key length will be 128-bits. If it's 136-bits
* it'll be null-padded to 192-bits and 192 bits will be the key length until {@link Crypt_AES::setKey() setKey()}

// instead, RC2 key expansion is used to extend it out to that length. this isn't done for AES / Rijndael since that doesn't define any
// sort of key expansion algorithm.
// admittedly, phpseclib is inconsistent in this regard. RC4 and Blowfish support arbitrary key lengths between a certain range, as well,
// and they don't have any way to set the key length. but then again, neither do those algorithms have their own key expansion algorithm,
// whereas RC2 does. and technically, AES / Rijndael (and even Twofish) don't support arbitrary key lengths - they support variable key
// lengths. so in some ways, i suppose this inconsistency somewhat makes sense, although the fact that Crypt_Twofish doesn't have a
// setKeyLength() function whereas Crypt_AES / Crypt_Rijndael do not is, itself, an inconsistency.
// but that said, Crypt_RC2 is inconsistent in other ways: if you pass a 128-bit (16-byte) key to it via setKey() the key is not treated
// as a 128-bit key but rather as a 1024-bit key and is expanded accordingly, not via null padding, but via RC2's key expansion algorithm.
// this behavior is in contrast to mcrypt, which extends keys via null padding to 1024 bits. it is also in contrast to OpenSSL, which
// extends keys, via null padding, to 128 bits. mcrypt's approach seems preferable as one can simulate 128 bit keys by using RC2's
// key expansion algorithm to extend the key to 1024 bits and then changing the first byte of the new key with an inverse pitable mapping.
// in contrast, to my knowledge, there is no technique for expanding a key less than 128 bits to 128 bits, via RC2 key expansion. the only
// scenario in that regard is null padding.
// simple truncation is insufficient, since, quoting RFC2268, "the purpose of the key-expansion algorithm [in RC2] is to modify the key buffer
// so that each bit of the expanded key depends in a complicated way on every bit of the supplied input key".
// now, to OpenSSL's credit, null padding is internally consistent with OpenSSL. OpenSSL only supports fixed length keys. For rc2, rc4 and
// bf (blowfish), all keys are 128 bits (or are null padded / truncated accordingly). to use 40-bit or 64-bit keys with RC4 with OpenSSL you
// don't use the rc4 algorithm - you use the rc4-40 or rc4-64 algorithm. and similarily, it's not aes-cbc that you use - it's either aes-128-cbc
// or aes-192-cbc or aes-256-cbc. this is in contrast to mcrypt, which (with the exception of RC2) actually supports variable and arbitrary
// length keys.
// superficially, it seens like Rijndael would be another exception to mcrypt's key length handling, but it in fact is not. the reason being that,
// with mcrypt, when you specify MCRYPT_RIJNDAEL_128 or MCRYPT_RIJNDAEL_192 or MCRYPT_RIJNDAEL_256 the numbers at the end aren't referring to the
// key length, but rather, the block length. ie. Rijndael, unlike most block ciphers, doesn't just have a variable (but not arbitrary) key length -
// it also has a variable block length. AES's block length, however, is not variable, so technically, only MCRYPT_RIJNDAEL_128 is AES.
