Problem: Elliptic.js use in client browser about elliptic HOT 12 CLOSED

@beastybeast you could use browserify to build browser bundle.

This could be done by:

1. npm install
2. make -B
3. ls dist/*

All files that are usable in browser are in dist/ folder.

And as far as I remember - they are exported via elliptic global variable.

Sorry but I can not use "npm install" etc as I do not have NodeJS as the backend - do I need to install it?
Why can I not just take the file elliptic.js from the dist folder and include it in my header files for the browser?

Try to click the link : https://pcrypt.org/dev/ecc.php

and see the result!

Everything need to be browser client based.

Ok, I just did it for you. You could pick up js files from dist/ folder.

And node.js is not required for this.

Thank you, but the problem is still the same?

I have downloaded this version and updated - EC and elliptic is still unknown for javascript?

from elliptic.

Oh, sorry. It is ellipticjs, not just elliptic

from elliptic.

Great. now it seams to work.

Just needed to modify the initialisation to this:

var ec = new ellipticjs.ec('secp256k1');

You may need to update the documentation?

NB: Please also see that ec is now lower case letters.

from elliptic.

It is in lower case in docs too:

var EC = require('elliptic').ec;

from elliptic.

Yes but that is NodeJS. Does not work with client javascript

from elliptic.

On the front page the initialization is:

var ec = new EC('secp256k1');

This will not work in client side javascript

Also:

var EC = require('elliptic').ec;

Will not run.

from elliptic.

Full work example in browser:

(function(){
    var ec = new elliptic.ec('curve25519');

    // Generate keys
    var key1 = ec.genKeyPair();
    var key2 = ec.genKeyPair();

    var shared1 = key1.derive(key2.getPublic());
    var shared2 = key2.derive(key1.getPublic());

    console.log('Both shared secrets are BN instances');
    console.log(shared1.toString(16));
    console.log(shared2.toString(16));
})();

Put this example in README.md may be better.
