I am trying to encrypt given plain text by Triple DES algorithm with CBC mode, but unable to get Desired Cipher Text which i have given below.

I need this encryption and decryption by CryptoJs using Javascript, but unable to do this.

Plain Text: "AN=1234567890;[email protected];TS=2009-06-03 17:04:39" Desired Cipher Text: "LK0Y/C2GWAfVguTEwFBIzlLBKsp4v61yHCUTj0iKtxcG60Hzprx/zlCofYHsjYWnJt78ao9l6cA7TE fIl+u0QA=="

Key = "1234567890ABCDEFGHIJKLMN"

IV = "12345678"

Mode: "CBC"

Algorithm : "TripleDES"

Just use CryptoJS's TripleDes method (CryptoJS.TripleDES.encrypt) to encrypt. Should do the work. This matches what you want as you mentioned in your question.

Make sure to parse as UTF-8.

let data = "AN=1234567890;[email protected];TS=2009-06-03 17:04:39"
let key = "1234567890ABCDEFGHIJKLMN"
let IV = "12345678"
let cipher = CryptoJS.TripleDES.encrypt(data, CryptoJS.enc.Utf8.parse(key), {
  iv: CryptoJS.enc.Utf8.parse(IV),
  mode: CryptoJS.mode.CBC
});

console.log(cipher.toString())
<script src="https://cdnjs.cloudflare./ajax/libs/crypto-js/3.1.9-1/crypto-js.min.js"></script>
