WASM Crypto

Various Rust crypto libraries wrapped in WASM for use in Deno and the browser. This library is specifically made for use with Telegram crypto, but other non-telegram related things will be added here.

Usage

Be sure to build with --unstable.

import { igeEncrypt, igeDecrypt } from 'https://deno.land/x/wasm_crypto/mod.js';

const key = Uint8Array.from([0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f,
            0x10, 0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19, 0x1a, 0x1b, 0x1c, 0x1d, 0x1e, 0x1f])

const iv = Uint8Array.from([0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f,
            0x10, 0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19, 0x1a, 0x1b, 0x1c, 0x1d, 0x1e, 0x1f])

const plaintext = Uint8Array.from([0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f,
            0x10, 0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19, 0x1a, 0x1b, 0x1c, 0x1d, 0x1e, 0x1f])

const ciphertext = igeEncrypt(plaintext, key, iv)
const decrypted  = igeDecrypt(ciphertext, key, iv)

console.log('Original value: ', plaintext)
console.log('Encrypted value:', ciphertext)
console.log('Decrypted value:', decrypted)

Building

Building will require deno, rust, and wasm-pack. Once all dependencies are installed, just run:

deno run -A ./scripts/build.ts

mod.ts is not generated, so any new definitions will have to be manually added there.

Roadmap

The end goal for this project is to have all of the algorithms implemented that I possibly can. Since that will lead to very large WASM binaries though, I would like to eventually have different wasm/js files for different algorithm types (hashing, ciphers, etc). For now, however, everything will be bundled into a single binary.
