SipHash (2-4) implemented in pure Javascript and WebAssembly
npm install siphash24SipHash (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).
` js
var siphash24 = require('siphash24')
var hash = siphash24(Buffer.from('hello world'), Buffer.from('012345678012345678'))
console.log(hash, 'hash of "hello world" as a uint8array')
`
#### var hash = siphash24(input, key, [hash])
Hash a Uint8Array/buffer using siphash24.
* key should be a Uint8Array/buffer that is siphash24.KEYBYTES longhash
* 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.
