JAVASCRIPT Client encrypts PHP service-side decryption

Hi everyone.

I use CRYPTO-JS to encrypt the client:

function Encrypt (str) {    var key = $.cookie (' key ');    var encrypted = CryptoJS.TripleDES.encrypt (str, key, {Mode:CryptoJS.mode.ECB, padding:CryptoJS.pad.ZeroPadding});    return encrypted;}

Service side:

$decrypt = Mcrypt_decrypt (mcrypt_3des, $_session[' key '), $encrypted _str_from_client, MCRYPT_MODE_ECB); Print ($decrypt);

It can't be decrypted like this.

Do you have any way to do in the client with 3DES ECB mode encryption, the backend can be decrypted?
