Twofish:: (7 methods):
__construct()
setKeyLength()
_setupKey()
_mdsrem()
_encryptBlock()
_decryptBlock()
_setupInlineCrypt()
| __construct($mode = self::MODE_CBC) X-Ref |
| Default Constructor. Determines whether or not the mcrypt extension should be used. $mode could be: - CRYPT_MODE_ECB - CRYPT_MODE_CBC - CRYPT_MODE_CTR - CRYPT_MODE_CFB - CRYPT_MODE_OFB (or the alias constants of the chosen cipher, for example for AES: CRYPT_AES_MODE_ECB or CRYPT_AES_MODE_CBC ...) If not explicitly set, CRYPT_MODE_CBC will be used. param: int $mode |
| setKeyLength($length) X-Ref |
| Sets the key length. Valid key lengths are 128, 192 or 256 bits param: int $length |
| _setupKey() X-Ref |
| Setup the key (expansion) see: \phpseclib\Crypt\Base::_setupKey() |
| _mdsrem($A, $B) X-Ref |
| _mdsrem function using by the twofish cipher algorithm return: array param: string $A param: string $B |
| _encryptBlock($in) X-Ref |
| Encrypts a block return: string param: string $in |
| _decryptBlock($in) X-Ref |
| Decrypts a block return: string param: string $in |
| _setupInlineCrypt() X-Ref |
| Setup the performance-optimized function for de/encrypt() see: \phpseclib\Crypt\Base::_setupInlineCrypt() |
