Hashing
This benchmark compares various configurations of crypto.createHash from
Node.js core with crypto_generichash.
The winner is:
const { crypto_generichash } = require('sodium-universal/crypto_generichash')
const output = Buffer.alloc(64)
// Note! This reuses the same Buffer over and over again. You only own it until
// the next call. You can either copy it (the no prealloc test does this) or
// you can turn it into whatever string format you require
// (the prealloc, digest does this). Note that these two suggestions of course
// change the performance, so review the numbers in the tables below
function hash (data) {
crypto_generichash(output, data)
return output
