BLAKE3

BLAKE3 implementation adapted from connor4312/blake3 to make it work directly from a ES Module compatible browser.

Update: connor4312/blake3 now can be loaded directly from ES compatible browsers: connor4312/blake3#8 (comment)

This repository will not be updated anymore.

Changes

blake3_js.js was renamed to blake3.js.
blake3_js_bg.wasm was renamed to blake3_js_bg.wasm.
blake3.js was modified to use WebAssembly.instantiateStreaming instead of non-standard import * as wasm from './blake3_js_bg.wasm' (not supported by browsers because it's just a feature proposal).
As it's based on blake3_js.js the high level functions were removed.

Usage

Examples based on those tests.

// Import the module and wait for WASM module initialization
const blake3 = await import('./blake3.js')
await blake3.ready

// Hash 'wat'
let hasher = blake3.create_hasher()
hasher.update(new TextEncoder().encode('wat'))

// .digest() requires an array as an argument where the digest will be stored
let result = new Uint8Array(32)
hasher.digest(result)

// Output the digest in hexadecimal (so we compare the result with the linked test)
console.log(Array.from(result).map(e => e.toString(16).padStart(2, 0)).join(''))

// For the keyed hash first create a key
// The linked test creates a key by hashing the string 'test'
hasher = blake3.create_hasher()
hasher.update(new TextEncoder().encode('test'))
result = new Uint8Array(32)
hasher.digest(result)

// Create a key using the above key
const keyedHasher = blake3.create_keyed(result)

// The keyed hasher usage is the same as a normal hasher
keyedHasher.update(new TextEncoder().encode('wat'))
result = new Uint8Array(32)
keyedHasher.digest(result)
console.log(Array.from(result).map(e => e.toString(16).padStart(2, 0)).join(''))

You can test it here: https://qgustavor.github.io/blake3-wasm/test.html

A NPM module will not be published because I expect connor4312/blake3 to be fixed to work without requiring a bundler later or sooner.
