php 和 java共用的加密方法

http://www.php.net/manual/en/ref.mcrypt.php To have the same result in Java and PHP with the BouncyCastle library : php function encrypt($str, $operation, $key) { $ret = ''; $key = pack('H*', $key); if (strtoupper($operation) == 'DECODE')

To have the same result in Java and PHP with the BouncyCastle library :

php

function encrypt($str, $operation, $key) { $ret = ''; $key = pack('H*', $key); if (strtoupper($operation) == 'DECODE') { $str = pack('H*', $str); $ret = mcrypt_ecb(MCRYPT_BLOWFISH, $key, $str, MCRYPT_DECRYPT); } else { $ret = mcrypt_ecb(MCRYPT_BLOWFISH, $key, $str, MCRYPT_ENCRYPT); $ret = bin2hex($ret); } return $ret; }
