BLAKE2b and BLAKE2s hash functions compiled to WebAssembly using Emscripten and optimized for small size

For pure JavaScript implementation that is not performance-critical you might want to consider blakejs instead.

npm install blake2.wasm

Node.js:

var blake2 = require('blake2.wasm')

blake2.ready(function () {
    // Do stuff
});

Browser:

requirejs(['blake2.wasm'], function (blake2) {
    blake2.ready(function () {
        // Do stuff
    });
})

• callback - Callback function that is called when WebAssembly is loaded and library is ready for use

Create Blake2b object that can later be updated with data

• output_length - Length of output hash in bytes, defaults to full 512-bit hash (64 bytes)
• key - Secret key

Update instance with data

Get hash

Create Blake2s object that can later be updated with data

• output_length - Length of output hash in bytes, defaults to full 256-bit hash (32 bytes)
• key - Secret key

Update instance with data

Get hash

Take a look at src/index.ls for JsDoc sections with arguments and return types as well as methods description, look at tests/index.ls for usage examples.

Feel free to create issues and send pull requests (for big changes create an issue first and link it from the PR), they are highly appreciated!

When reading LiveScript code make sure to configure 1 tab to be 4 spaces (GitHub uses 8 by default), otherwise code might be hard to read.
