Share Code Generator

This is an NPM module which exposes two functions which are used for generating and helping verify share codes for the FT.

Encrypt

The encrypt function, encrypt(userId, articleId, salt, time, tokens, context=defaultContext), will return a share code for your application to use.

Decrypt

The decrypt function, decrypt(code, article, salt), will return

{
	tokens:  tokens,
	time:    time,
	user:    user,
	context: context
};

The decrypt function does not verify if the User ID actually corresponds with a User account, it if for your application to do those checks.

Development

This requires Node.JS to be installed on your system alongside NPM. Check-out the repository and run npm install in the directory. If that has worked you should now be able to run npm test, which should return all tests as passing. You are now ready to develop.

Test

npm test

Notes

signing

https://www.npmjs.com/package/node-rsa

var NodeRSA = require('node-rsa');
var key = new NodeRSA({b: 512});
 
var text = 'Hello RSA!';
var signature = key.sign(text, 'base64', 'utf8');

var checkSig = key.verify(buffer, signature, 'utf8', 'base64');
