How to generate an MD5 file hash in JavaScript/Node.js?

How to write functionToGenerateMD5hash for this code? I already have fileVideo and I need to send the corresponding md5 hash to the server by clicking on the button.

$("#someButton").click(function() {
var fr = new FileReader();      
fr.onload = function(e) {            
    string md5 = functionToGenerateMD5hash(e.target.result);
    // send md5 here
};       
fr.readAsArrayBuffer(fileVideo);

Also, can you use this to generate a MD5 hash in Node.js?

If you don't want to use libraries or other things, you can use this native javascript approach:

var MD5 = function(d){var r = M(V(Y(X(d),8d.length)));return r.toLowerCase()};function M(d){for(var ,m="0123456789ABCDEF",f="",r=0;r=d.charCodeAt(r),f+=m.charAt(>>>4&15)+m.charAt(15&);return f}function X(d){for(var =Array(d.length>>2),m=0;m<.length;m++)_[m]=0;for(m=0;m<8d.length;m+=8)[m>>5]|=(255&d.charCodeAt(m/8))<}function V(d){for(var ="",m=0;m<32*d.length;m+=8)+=String.fromCharCode(d[m>>5]>>>m%32&255);return }function Y(d,){d[>>5]|=128<<%32,d[14+(+64>>>9<<4)]=;for(var m=1732584193,f=-271733879,r=-1732584194,i=271733878,n=0;n,m,f,r,i){return safe_add(bit_rol(safe_add(safe_add(,d),safe_add(f,i)),r),m)}function md5_ff(d,,m,f,r,i,n){return md5_cmn(&m|~&f,d,,r,i,n)}function md5_gg(d,,m,f,r,i,n){return md5_cmn(&f|m&~f,d,,r,i,n)}function md5_hh(d,,m,f,r,i,n){return md5_cmn(^m^f,d,,r,i,n)}function md5_ii(d,,m,f,r,i,n){return md5_cmn(m^(|~f),d,,r,i,n)}function safe_add(d,){var m=(65535&d)+(65535&);return(d>>16)+(>>16)+(m>>16)<<16|65535&m}function bit_rol(d,){return d<<|d>>>32-_}

/** NORMAL words**/ var value = 'test';

var result = MD5(value);

document.body.innerHTML = 'hash - normal words: ' + result;

/** NON ENGLISH words**/ value = 'מבחן'

//unescape() can be deprecated for the new browser versions result = MD5(unescape(encodeURIComponent(value)));

document.body.innerHTML += '

hash - non english words: ' + result;

For non english words you may need to use unescape() and the encodeURIComponent() methods.

CryptoJS is a crypto library which can generate md5 hash among others:

Usage with Script tag:

<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/4.0.0/core.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/md5.js"></script>
<script>
   var hash = CryptoJS.MD5("Message");
   alert(hash);
</script>

Alternatively with ES6:

npm install crypto-js

import MD5 from "crypto-js/md5";
console.log(MD5("Message").toString());

You can also use modular imports:

var MD5 = require("crypto-js/md5");
console.log(MD5("Message").toString());

Github: https://github.com/brix/crypto-js

CDN: https://cdnjs.com/libraries/crypto-js

You could use crypto-js.

I would also recommend using SHA256, rather than MD5.

To install crypto-js via NPM:

npm install crypto-js

Alternatively you can use a CDN and reference the JS file.

Then to display a MD5 and SHA256 hash, you can do the following:

<script type="text/javascript">
    var md5Hash = CryptoJS.MD5("Test");
    var sha256Hash = CryptoJS.SHA256("Test1");

    console.log(md5Hash.toString());
    console.log(sha256Hash.toString());
</script>

Working example located here, JSFiddle

There are also other JS functions that will generate an MD5 hash, outlined below.

Then simply use the MD5 function, as shown below:

alert(md5("Test string"));

As a contemporary alternative, there is a standard now for client side cryptography. This has the advantage of being optimised by the browser itself.

Taken from the example in the documentation:

async function sha256(message) {

    // encode as UTF-8
    const msgBuffer = new TextEncoder('utf-8').encode(message);

    // hash the message
    const hashBuffer = await crypto.subtle.digest('SHA-256', msgBuffer);
    
    // convert ArrayBuffer to Array
    const hashArray = Array.from(new Uint8Array(hashBuffer));

    // convert bytes to hex string
    const hashHex = hashArray.map(b => ('00' + b.toString(16)).slice(-2)).join('');
    return hashHex;
}

sha256('abc').then(hash => console.log(hash));

(async function() {
    const hash = await sha256('abc');
}());

MD5 is likely unsupported, however the likes of SHA-256, SHA-384, and SHA-512 are.

And those will likely be able to be calculated server side also.

Here's some documentation on usage: https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/digest

And cross browser compatibility: https://caniuse.com/#feat=cryptography

Here's a simplified and minified version (about 3.5k) of this nice implementation:

The function will return an uppercase 32-character string like 098F6BCD4621D373CADE4E832627B4F6.

For simple alphanumeric strings, you can run it like this:

md5('test')

If you need full unicode support, you can call unescape and encodeURIComponent on the string before passing it:

md5(unescape(encodeURIComponent('😊')))

Added Unicode support to @valdeci and @Derzu versions.
It can be used to md5-ize JSON objects too.
Added incompatibility with IE11 and below :)

You can use a lightweight library pure-md5. Just a 4.7kb.

$("#file-dialog").change(function() {
  handleFiles(this.files);
});

function handleFiles(files) {
  for (var index = 0; index < files.length; index++) {
    var file = files[index];
    var fileReader = new FileReader();
    fileReader.onload = function(e) {
      $('body').append(`
        <div style="margin-top: 2rem;">
          <span>${file.name}: </span>
          <span>${(md5(e.target.result))}</span>
        </div>
      `);
    }

    fileReader.readAsText(file, 'utf-8');
  }

}

You can use crypto-js.

To use crypto-js, you need to load core.js then md5.js .

A list of URLs are here https://cdnjs.com/libraries/crypto-js

cryptojs is also available in zip form here https://code.google.com/archive/p/crypto-js/downloads

There is an answer from answerer 'amal' in 2013, that is similar to this but a)his link to md5.js no longer works b)he didn't load core.js beforehand, which is necessary.
