sha1.wasm

WebAssembly port of SHA-1

``bash
npm i @hazae41/sha1.wasm
`

Node Package 📦

Features

`typescript
import { Sha1Wasm, Memory, sha1 } from "@hazae41/sha1.wasm";

// Wait for WASM to load
await Sha1Wasm.initBundled();

// Data to be hashed
const hello = new TextEncoder().encode("Hello World")

// Pass to WASM
using memory = new Memory(hello)

// Grab the digest
using digest = sha1(memory)

console.log(digest.bytes) // Uint8Array
`

`typescript
import { Sha1Wasm, Memory, Sha1Hasher } from "@hazae41/sha1.wasm";

// Wait for WASM to load
await Sha1Wasm.initBundled();

// Create a hash
using hasher = new Sha1Hasher()

// Data to be hashed
const hello = new TextEncoder().encode("Hello World")

// Pass to WASM
using memory = new Memory(hello)

// Update the hash with your data
hasher.update(memory)

// Grab the digest
using digest = hasher.finalize()

// Update the hash another time
hasher.update(memory)

// Grab the digest
using digest2 = hasher.finalize()

// digest !== digest2
console.log(digest.bytes)
console.log(digest2.bytes)

Building

$3

You need to install Rust

Then, install wasm-pack

`bash
cargo install wasm-pack
`

Finally, do a clean install and build

`bash
npm ci && npm run build
`

$3

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

`bash
docker compose up --build
`

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

`bash
npm diff
``

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

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!
