data-2-hash

The main approach of this module is CLI interface for crypto.

But it also provide a tiny wrapper for crypto so you can use crypto a little bit easier.

Getting Started

Install last version of data-2-hash by executing:

npm install data-2-hash --save # Local
npm install -g data-2-hash # Global (will be available CLI)

You can require data-2-hash in your NodeJS project and use it.

var Hash = require('data-2-hash');

// Create empty hash instance
var shasum = new Hash('sha');
console.log(shasum.update('test').digest());

// Create hash instance with predefined data
console.log(new Hash('md5', 'test').digest());

// Calculate hash for some file
new Hash('md5', 'file.md', true).on('done', function(digest) {
    console.log(digest);
});

CLI

If you install data-2-hash as global module, you can use CLI.
