Usage
import { RsaWasm, Memory, RsaPrivateKey } from "@hazae41/rsa.wasm";
// Wait for WASM to load
await RsaWasm.initBundled();
using keypair = new RsaPrivateKey(2048)
using identity = keypair.to_public_key()
using message = new Memory(new TextEncoder().encode("hello world"))
using signature = keypair.sign_pkcs1v15_unprefixed(message)
const verified = identity.verify_pkcs1v15_unprefixed(message, signature)
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 git status
git status --porcelain
If the output is empty then the bytecode is the same as the one I commited
Automated checks
Each time I commit to the repository, the GitHub's CI does the following:
- Clone the repository
- Reproduce the build using
docker compose up --build
- Throw an error if the
git status --porcelain
output is not empty
Each time I release a new version tag on GitHub, the GitHub's CI does the following:
- Clone the repository
- Do not reproduce the build, as it's already checked by the task above
- Throw an error if there is a
npm diff
between the cloned repository and the same version tag on NPM
If a version is present on NPM but not on GitHub, do not use!
