php服务端：

$text = "Message";
$key = md5($text); //key的长度必须16，32位,这里直接MD5一个长度为32位的key
$iv='1234567812345678';
//$crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $text, MCRYPT_MODE_CBC, $iv);
//var_dump(base64_encode($crypttext));
$crypttext = base64_decode('JtChGnqjPCCXTclGCYHsag==');
$decode = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key, $crypttext, MCRYPT_MODE_CBC, $iv);
//echo base64_encode($crypttext);
//echo "<br/>";
echo $decode."\n";
//echo "<br/>";
