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.

1import {
2    KrBcrypt,
3    KrHash,
4    KrHashAlgorithm,
5    KrRSA,
6    KrRSAKeyPair
7} from "element-ts/krypton";

Examples

KrBcrypt

1const password: string = "1234";
2const createdPassword: Buffer = await KrBcrypt.createPassword(password);
3const checkPassword: boolean = await KrBcrypt.verifyPassword(password, createdPassword);

KrHash

1const hashedData: Buffer = KrHash.hash(Buffer.from("Hello, world!");
2const hashedData: Buffer = KrHash.hash(Buffer.from("Hello, world!", KrHashAlgorithm.sha512));
3
4const hasher: KrHash = new KrHash()
5hasher.append(Buffer.from("Hello"));
6hasher.append(Buffer.from("World"));
7const hashedData: Buffer = hasher.hash();

KrCipher

1// instance
2const cipher: KrCipher = new KrCipher(Buffer.from("password"));
3const msg: Buffer = Buffer.from("Hello, world!");
4const encryptedData: Buffer = cipher.encrypt(msg);
5const decryptedData: Buffer = cipher.decrypt(encryptedData);
6console.log(msg === decryptedData);
7
8// static
9const encryptedData: Buffer = KrCipher.encrypt(Buffer.from("Hello, world!"), Buffer.from("password"), Buffer.from("the-salt"));
10const decryptedData: Buffer = KrCipher.decrypt(encryptedData, Buffer.from("password"), Buffer.from("the-salt"));
11

KrRSA

1
2const keys: KrRSAKeyPair = KrRSA.generateKeys();
3
4const message: string = "Hello, world!";
5const dataUnEncrypted: Buffer = Buffer.from(message);
6const dataEncrypted: Buffer = KrRSA.encrypt(dataUnEncrypted, keys.publicKey);
7const dataDecrypted: Buffer = KrRSA.decrypt(dataEncrypted, keys.privateKey);
8
9const messageDecrypted: string = dataDecrypted.toString("utf8");
