I tried to hash a text in client-side. I used following code to hash it, but it shows this Reference Error.

<html>
<head>
 <script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/md5.js">
 </script>
</head>
<body>
 <script>
 var plaintext = "hiii";
 var encrptedText = CryptoJs.md5(plaintext);
 alert("Encrpted Text : " + encrptedText.toString());
 </script>
</body>
</html>

  • There’s an error in the JS file itself. Commented Dec 28, 2018 at 10:21

    the variable is named CryptoJS not CryptoJs Commented Dec 28, 2018 at 10:24
  • If you try to evaluate the script in the browser console, you get the following error: Uncaught TypeError: Cannot read property 'lib' of undefined Commented Dec 28, 2018 at 10:24

Use the entire package - not just the md5 module - change the src in your script tag 

<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/crypto-js.js"></script></head>
<body>
<script>
var plaintext="hiii";
var encrptedText = CryptoJS.MD5(plaintext)
alert("Encrpted Text : "+ encrptedText.toString());
</script>
 </body>
</html>

If for you important the size of extended libraries, that you can use pure-md5 (4.76kb) instead crypto-js (187.44kb).

<html>
<head>
<script src="https://unpkg.com/pure-md5@latest/lib/index.js">
 </script>
</head>
<body>
 <script>
 var plaintext = "hiii";
 var encrptedText = md5(plaintext);
 alert("Encrpted Text : " + encrptedText.toString());
 </script>
</body>
</html>
