| __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. Key lengths can be between 32 and 448 bits. param: int $length |
| isValidEngine($engine) X-Ref |
| Test for engine validity This is mainly just a wrapper to set things up for \phpseclib\Crypt\Base::isValidEngine() return: bool see: \phpseclib\Crypt\Base::isValidEngine() param: int $engine |
| _setupKey() X-Ref |
| Setup the key (expansion) see: \phpseclib\Crypt\Base::_setupKey() |
| _bcrypt_hash($sha2pass, $sha2salt) X-Ref |
| bcrypt return: string param: string $sha2pass param: string $sha2salt |
| bcrypt_pbkdf($pass, $salt, $keylen, $rounds) X-Ref |
| Performs OpenSSH-style bcrypt return: false|string param: string $pass param: string $salt param: int $keylen param: int $rounds |
| _expand0state($key, &$sbox0, &$sbox1, &$sbox2, &$sbox3, &$p) X-Ref |
| Key expansion without salt see: self::_bcrypt_hash() param: int[] $key param: int[] $sbox0 param: int[] $sbox1 param: int[] $sbox2 param: int[] $sbox3 param: int[] $p |
| _expandstate($data, $key, &$sbox0, &$sbox1, &$sbox2, &$sbox3, &$p) X-Ref |
| Key expansion with salt see: self::_bcrypt_hash() param: int[] $data param: int[] $key param: int[] $sbox0 param: int[] $sbox1 param: int[] $sbox2 param: int[] $sbox3 param: int[] $p |
| _encryptBlock($in) X-Ref |
| Encrypts a block return: string param: string $in |
| _encryptBlockHelperFast($x0, $x1, $sbox0, $sbox1, $sbox2, $sbox3, $p) X-Ref |
| Fast helper function for block encryption return: int[] param: int $x0 param: int $x1 param: int[] $sbox0 param: int[] $sbox1 param: int[] $sbox2 param: int[] $sbox3 param: int[] $p |
| _encryptBlockHelperSlow($x0, $x1, $sbox0, $sbox1, $sbox2, $sbox3, $p) X-Ref |
| Slow helper function for block encryption return: int[] param: int $x0 param: int $x1 param: int[] $sbox0 param: int[] $sbox1 param: int[] $sbox2 param: int[] $sbox3 param: int[] $p |
| _decryptBlock($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() |
