    siphash24

    SipHash (2-4) implemented in pure Javascript and WebAssembly.

    npm install siphash24
    

    The Javascript fallback is adapted from https://github.com/jedisct1/siphash-js to support Uint8Arrays and the (fast!) WebAssembly implementation is hand written.

    When using the WASM implementation this module is almost as fast as the C version (around 10% slower on my laptop).

    Usage

    var siphash24 = require('siphash24')
    var hash = siphash24(Buffer.from('hello world'), Buffer.from('012345678012345678'))
    
    console.log(hash, 'hash of "hello world" as a uint8array')

    API

    var hash = siphash24(input, key, [hash])

    Hash a Uint8Array/buffer using siphash24.

    • key should be a Uint8Array/buffer that is siphash24.KEYBYTES long
    • hash can to be optionally passed as the output buffer and should be siphash24.BYTES long.

    Returns the hash as a Uint8Array.

    siphash24.WASM_SUPPORTED

    Boolean informing you if your runtime supports WASM.

    siphash24.WASM_LOADED

    Boolean informing you if the WASM implementation has been loaded.
