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

php

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