How to get original string back in CryptoJS using TripleDES?

Question

I'm trying to encrypt and decrypt in JavaScript using TripleDES.js. Here is my code snippet:

Encryption Method:

encrypt_string = function (plainData) {

   var encrypted = CryptoJS.TripleDES.encrypt(plainData, "My Secret Key");

   alert("Encrypted: " + encrypted);

}

Decryption Method:

decrypt_string = function (cipherData) {

   var decrypted = CryptoJS.TripleDES.decrypt(cipherData, "My Secret Key");

   alert("Decrypted: " + decrypted);

}

While passing plainData as Gokul Nath, to encrypt_string(), the alert message shows:

U2FsdGVkX1/huVhh9IQhJF72gcs26f1l0+hNSsWEXsc=

While passing cipherData as U2FsdGVkX1/huVhh9IQhJF72gcs26f1l0+hNSsWEXsc=, to decrypt_string(), the alert message shows:

476f6b756c204e617468

Question: How to get the original plain data while decrypting?

Answer 1

476f6b756c204e617468 is the hex representation of the original string:

47 6f 6b 75 6c 20  4e 61 74 68
G  o  k  u  l  |/  N  a  t  h
               |
               +-> this is a space

You can use something like decrypted.toString(CryptoJS.enc.Latin1) to get the string value, as per:

<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/tripledes.js"></script>
<script>
    var encrypted = CryptoJS.TripleDES.encrypt("Gokul Nath", "My Secret Key");
    var decrypted = CryptoJS.TripleDES.decrypt(encrypted, "My Secret Key");
    alert("Decrypted: " + decrypted.toString(CryptoJS.enc.Latin1));
</script>

which gives:
