Usage

import { Argon2, Argon2Deriver, Memory } from "@hazae41/argon2.wasm";

// Wait for WASM to load
await Argon2.initBundled();

using pass = new Memory(crypto.getRandomValues(new Uint8Array(256)))
using salt = new Memory(crypto.getRandomValues(new Uint8Array(32)))

using deriver = new Argon2Deriver("argon2d", 19, 16384, 12, 2)
using derived = deriver.derive(pass, salt)

console.log(derived.bytes)

Building

Unreproducible building

You need to install Rust

Then, install wasm-pack

cargo install wasm-pack

Finally, do a clean install and build

npm ci && npm run build

Reproducible building

You can build the exact same bytecode using Docker, just be sure you're on a linux/amd64 host

docker compose up --build

Then check that all the files are the same using npm diff

npm diff

If the output is empty then the bytecode is the same as the one I commited

Automated checks

Each time I release a new version on GitHub, the GitHub's CI clones the GitHub repository, reproduces the build, and throws an error if the NPM release is different. If a version is present on NPM but not on GitHub, do not use it!
