We use node.js for that, you execute it from inside 4GL, but it is much easier to do it in a global language like js. We did this for the Angolan Legislation, if you need we can share this know how. Cheers.

Hi, I finnaly started to develop the function with the base I found in Sage X3 Help on the Crypto bundle.
I changed a bit the code to encrypt in SHA256:

"use strict";

var crypto = require('crypto');

// computes hash in SHA256 digest, returns it as a hex string.
exports.digestsha256(text) {
var hash = crypto.createHash('sha256');
hash.update(text, 'utf8');
return hash.digest('hex');
}

But, when i run the X3 script

STATUSCODE = func ASYRWEBSER.EXEC_JS("bundles/yeth-crypto/lib/crypto-helper", "digestsha256", "sync", '"helloworld"', "0", 0, "", "0", RESHEAD, RESBODY)

The STATUSCODE is always 500, and I don't have 

Have you any clue on that problem?

Thanks

I found the solution,
The sample in X3 help doesn't work as it is.

but with the keyword function, it's OK

"use strict";

var crypto = require('crypto');

// computes hash in SHA256 digest, returns it as a hex string.
exports.digestsha256 = function(text) {
    var hash = crypto.createHash('sha256');
    hash.update(text, 'utf8');
    return hash.digest('hex');
}
