crypto-lib

Javascript lib for crypto operations

npm install @m4ver!ck/crypto-lib

Usage

ES6 import for typical API call signing use case:

import sha1 from 'crypto/sha1';
import hmacSHA512 from 'crypto/hmac-sha512';
import Base64 from 'crypto/enc-base64';

const message, nonce, path, privateKey; // ...
const hashDigest = sha1(nonce + message);
const hmacDigest = Base64.stringify(hmacSHA512(path + hashDigest, privateKey));

AES Encryption

Plain text encryption

var Crypto = require("crypto");

// Encrypt
var ciphertext = Crypto.AES.encrypt('my message', 'secret key 123').toString();

// Decrypt
var bytes  = Crypto.AES.decrypt(ciphertext, 'secret key 123');
var originalText = bytes.toString(Crypto.enc.Utf8);

console.log(originalText); 

Object encryption

var Crypto = require("crypto");

var data = [{id: 1}, {id: 2}]

// Encrypt
var ciphertext = Crypto.AES.encrypt(JSON.stringify(data), 'secret key 123').toString();

// Decrypt
var bytes  = Crypto.AES.decrypt(ciphertext, 'secret key 123');
var decryptedData = JSON.parse(bytes.toString(Crypto.enc.Utf8));

console.log(decryptedData); // [{id: 1}, {id: 2}]
