How to translate hashing with 'openssl passwd -1 -salt $salt $data' to node.js

I am trying to imitate the behaviour of openssl passwd -1 -salt k7Ko8SgF di6cqUaQBuUOd7WhURXDq04022 in nodejs.

The result of this operation is $1$k7Ko8SgF$CN8PPKddtp5gONSRp4B56/ and I know the hash is the 4th section after the third '$'.

If I try:

const crypto = require('crypto');
const newsalt = 'k7Ko8SgF'; 
const key = 'di6cqUaQBuUOd7WhURXDq04022';
let sign = crypto.createHash('md5').update(newsalt + key).digest("base64");
console.log(sign);

I get n0cLvfi4LQFpIVbZ94gCIA==

I am not even sure the digest("base64") is even correct to be honest, as I don't know what exactly does openssl spit out.

I am unable to obtain the same hash string that I get with openssl. I need to get the same hash, as the program with which I am trying to communicate doesn't work unless the hash provided is produced with openssl as specified above.

Maybe someone can point me in the write direction?

Thanks in advance!

Solution

Thanks to @Topaco the best way to emulate the behaviour of openssl passwd -1 -salt yoursalt password on NodeJS is using the nano-MD5 library found here Hope this helps someone else looking into this same problem!
