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.

	WebCrypto	WebAssembly	Javascript
AES
`AES-CBC`	✔️	❌	✔️
`AES-ECB`	❌	❌	✔️
RSA
`RSA-PKCS1 v1.5`	❌	❌	✔️
`RSA-OAEP`	✔️	❌	✔️

More algorithm supports is one the way

AES

Example

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

const aes = new AES("Hello World AES!", {
  mode: "cbc",
  iv: "random 16byte iv",
});

const ciper = await aes.encrypt("This is AES-128-CBC. It works.");
console.log(ciper.hex());
// 41393374609eaee39fbe57c96b43a9da0d547c290501be50f983ecaac6c5fd1c

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

Syntax

new AES(key, {
  mode: "cbc" | "ebc", // default cbc
  iv: string | UInt8Array, // default [0, 0, ...., 0]
  padding: "pkcs5", // default pkcs5
});

RSA

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

const publicKey = RSA.parseKey(Deno.readTextFileSync("./public.pem"));
const ciper = await new RSA(publicKey).encrypt("Hello World");
console.log(ciper.base64());

const privateKey = RSA.parseKey(Deno.readTextFileSync("./private.pem"));
const plain = await new RSA(privateKey).decrypt(ciper);
console.log(plain.toString());

// More examples:
new RSA(publicKey);
new RSA(publicKey, { padding: "oaep", hash: "sha256" });
new RSA(publicKey, { padding: "pkcs1" });
