在JavaScript中加密字符串并使用RSA技术在PHP中解密

我试图加密JavaScript中的一些文本,然后将其发送到PHP(等:使用Ajax)在那里解密并保存(等等:在MySQL中).

到目前为止,这是我的代码:

在JavaScript中:

我正在使用此库进行加密:http: //travistidwell.com/blog/2013/02/15/a-better-library-for-javascript-asymmetrical-rsa-encryption/

function ConvertToURL(data) {
    // Converts data to URL friendly form
    // etc: Replaces '+', '/', '=' with 'plus', 'slash', 'equal'
};
function AjaxOrder(data) {
    // Sends data in PHP with Ajax
}

var publicKey = '-----BEGIN PUBLIC KEY-----
MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDlOJu6TyygqxfWT7eLtGDwajtN
FOb9I5XRb6khyfD1Yt3YiCgQWMNW649887VGJiGr/L5i2osbl8C9+WJTeucF+S76
xFxdU6jE0NQ+Z+zEdhUTooNRaY5nZiu5PgDB0ED/ZKBUSLKL7eibMxZtMlUDHjm4
gwQco1KRMDSmXSMkDwIDAQAB
-----END PUBLIC KEY-----';

var encrypt = new JSEncrypt();
encrypt.setPublicKey(publicKey);
var encrypted = encrypt.encrypt('Text to send.');

*// And now I am sending the encrypted text with some Ajax function*

AjaxOrder(ConvertToURL(encrypted));

在PHP中:

$dataPost = $_POST('dt');

function ConvertFromURL($data) {
    // Converts $data to original form
    // etc: Replaces 'plus', 'slash', 'equal' with '+', '/', '='
}
function ReturnData($data) {
    // Sends $data back in JavaScript as an answer to Ajax
}

$privateKey = '-----BEGIN RSA PRIVATE KEY-----

-----END RSA PRIVATE KEY-----';

openssl_private_decrypt(ConvertFromURL($dataPost), $decryptedWord, $privateKey);

ReturnData(base64_encode($decryptedWord));

现在PHP的答案每次都是空的.任何使这项工作的想法？
