node-noobcrypt

Node module providing easy methods for encryption.

node-noobcrypt

There are two types of encryption: one that will prevent your sister from reading your diary and one that will prevent your government.

  • Bruce Schneier

In the new era of Snowden and the NSA we need encryption tools accessible for everyone.

I really like ursa and I love encryption, but I wonder if anyone comes up quickly with a solution of encryptions buffer-length limitations. This module provides easy encryption for strings and buffers with any length!

It's quite useless for experienced users, but I hope with many following pull-requests it will help every user to develop an encrypted app quickly.

npm install node-noobcrypt
var crypt = require('node-noobcrypt');
var keypair = crypt.generateKeypair(); // [ publicKey, privateKey ] 
 
crypt.encrypt('Hello World!', keypair[0], function(data) {
    crypt.decrypt(data, keypair[1], function(decrypted) {
        console.log(decrypted.toString()); // Hello World! 
    });
});

Generates a new Keypair with a strength of 2048 bits and an exponent of 65537. Returns an array with two objects: The public key and the private key.

Encrypts a given buffer or string using a public key object. The encrypted data is returned via the callback function.

The encrypted data is a chain of base64 encoded strings joined by a '$'-sign.

Decrypts encrypted data using a private key object. The decrypted data is returned via the callback function.

Creates and returns a public key object from a given string in the PEM-format.

Creates and returns a private key object from a given string in the PEM-format.

Creates and returns a string in the PEM-format from a given public key object.

Creates and returns a string in the PEM-format from a given private key object.
