PHP如何实现AES加密解密算法

本文实例讲述了PHP简单AES加密解密算法。分享给大家供大家参考，具体如下：

function ecryptdString($str,$keys="6461772803150152",$iv="8105547186756005",$cipher_alg=MCRYPT_RIJNDAEL_128){  $encrypted_string = bin2hex(mcrypt_encrypt($cipher_alg, $keys, $str, MCRYPT_MODE_CBC,$iv));  return $encrypted_string;}function decryptStrin($str,$keys="6461772803150152",$iv="8105547186756005",$cipher_alg=MCRYPT_RIJNDAEL_128){  $decrypted_string = mcrypt_decrypt($cipher_alg, $keys, pack("H*",$str),MCRYPT_MODE_CBC, $iv);  return $decrypted_string;}
