God Crypto

A pure Javascript/Typescript cryptography implementation for Deno. We will try to use WebCrypto if available, then fallback to WebAssembly implementation if available, otherwise, we will use pure Javascript implementation.

NOTE: god_crypto is in very early stage of development. There will be a lot of change and it is not recommended for production.

Modules

You can choose to include the whole god_crypto implementation or just include module that you need.

// Load everything
import { AES, RSA, TOTP, hmac, encode } from "https://deno.land/x/god_crypto/mod.ts";

// Load what you need
import { AES }  from "https://deno.land/x/god_crypto/aes.ts";
import { RSA }  from "https://deno.land/x/god_crypto/rsa.ts";
import { TOTP } from "https://deno.land/x/god_crypto/otp.ts";
import { hmac } from "https://deno.land/x/god_crypto/hmac.ts";

Support Algorithms

More algorithm supports is one the way

Examples

import { AES } from "https://deno.land/x/god_crypto/aes.ts";

const aes = new AES("Hello World AES!", {
  mode: "cbc",
  iv: "random 16byte iv",
});
const cipher = await aes.encrypt("This is AES-128-CBC. It works.");
console.log(cipher.hex());
// 41393374609eaee39fbe57c96b43a9da0d547c290501be50f983ecaac6c5fd1c

const plain = await aes.decrypt(ciper);
console.log(plain.toString());
// This is AES-128-CBC. It works.

import { RSA } from "https://deno.land/x/god_crypto/rsa.ts";

// Parsing public/private key
const publicKey = RSA.parseKey(Deno.readTextFileSync("./public.pem"));
const privateKey = RSA.parseKey(Deno.readTextFileSync("./private.pem"));

const cipher = await new RSA(publicKey).encrypt("Hello World");
console.log(ciper.base64());

const plain = await new RSA(privateKey).decrypt(cipher);
console.log(plain.toString());
