PHP你可以使用mycrypt http://www.php.net/manual/en/mcrypt.examples.php RSA,DES,AES,Blowfish,MD5,SHA,X509,RC4以上加密也支持

用法闪光

// instance of crypto class
 private var _crypto : CryptoCode;
 public var myLoader : URLLoader;

// create instance with encryption key
 _crypto = new CryptoCode("PASSWORD");

// send crypted string to PHP script
 var variables : URLVariables = new URLVariables();
 variables.message = _crypto.encrypt(tosend_in.text);

// create request with POST method
 var request : URLRequest = new URLRequest("http://www.lecrabe.net/wordpress/demo/crypt/scripts/testcrypto.PHP");
 request.method = URLRequestMethod.POST;
 request.data = variables;

 // send request
 myLoader.load(request);

用法PHP

include_once "lib/cryptlib.PHP";

// init a new instance of Crypto Class
$crypto = new Crypt;

// init with the encryption key
$result = $crypto->init("PASSWORD");

// get the POST data
$messagefromflash = $_POST ["message"];

// decrypt data
$decrypted_messagefromflash = $crypto->decrypt(utf8_decode($messagefromflash));
