# PHP篇
跨语言加解密的要求是:AES/CBC/ZeroPadding 128位模式,key和iv一样,编码统一用utf-8。不支持ZeroPadding的就用NoPadding.
'; echo(base64_encode($encrypted)); echo '
'; //解密 $encryptedData = base64_decode("2fbwW9+8vPId2/foafZq6Q=="); $decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $privateKey, $encryptedData, MCRYPT_MODE_CBC, $iv); echo($decrypted); ?>
