origami-crypto-utils v0.3.4

Origami crypto utils

Purpose

Provided common utilitary methods for cryptographic functions:

• generate new key pairs
• encrypt data
• sign data
• decrypt data
• verify signatures
• encrypt and sign in the same step
• decrypt and sign in the same step

It uses PCKS1-PEM key formats.

Usage

var crypto = require('origami-crypto-utils');

var key1 = crypto.randomKey();
var key2 = crypto.randomKey();

var encrypted = crypto.encryptAndSign(
  {
    hello: 'there'
  },
  key1, // private key for signing,
  key2 // public key for encrypting
);

var decrypted = crypto.decryptAndVerify(
  encrypted,
  key2, // private key for decrypting
  key1 // public key for signature verification
);
