krypton

A very light weight package written in Typescript combining node/crypto and bcrypt for some helpful methods.

NOTE, I am not using my own crypto with this project, it is using recommend crypto from node and bcrypt.

Import

Import what you need. You will most likely not need to import all of these.

import {
    KrBcrypt,
    KrHash,
    KrHashAlgorithm,
    KrRSA,
    KrRSAKeyPair
} from "element-ts/krypton";

Examples

KrBcrypt

const password: string = "1234";
const createdPassword: Buffer = await KrBcrypt.createPassword(password);
const checkPassword: boolean = await KrBcrypt.verifyPassword(password, createdPassword);

KrHash

const hashedData: Buffer = KrHash.hash(Buffer.from("Hello, world!");
const hashedData: Buffer = KrHash.hash(Buffer.from("Hello, world!", KrHashAlgorithm.sha512));

const hasher: KrHash = new KrHash()
hasher.append(Buffer.from("Hello"));
hasher.append(Buffer.from("World"));
const hashedData: Buffer = hasher.hash();

KrCipher

// instance
const cipher: KrCipher = new KrCipher(Buffer.from("password"));
const msg: Buffer = Buffer.from("Hello, world!");
const encryptedData: Buffer = cipher.encrypt(msg);
const decryptedData: Buffer = cipher.decrypt(encryptedData);
console.log(msg === decryptedData);

// static
const encryptedData: Buffer = KrCipher.encrypt(Buffer.from("Hello, world!"), Buffer.from("password"), Buffer.from("the-salt"));
const decryptedData: Buffer = KrCipher.decrypt(encryptedData, Buffer.from("password"), Buffer.from("the-salt"));

KrRSA

const keys: KrRSAKeyPair = KrRSA.generateKeys();

const message: string = "Hello, world!";
const dataUnEncrypted: Buffer = Buffer.from(message);
const dataEncrypted: Buffer = KrRSA.encrypt(dataUnEncrypted, keys.publicKey);
const dataDecrypted: Buffer = KrRSA.decrypt(dataEncrypted, keys.privateKey);

const messageDecrypted: string = dataDecrypted.toString("utf8");
