@rvagg/blake2 Node.js BLAKE2 addon

Supports BLAKE2b and BLAKE2s using the SSE optimized reference implementation.

See https://github.com/dcposch/blakejs for a pure JavaScript implementation that works in the browser. This implementation is for Node.js only and requires a compile toolchain on a supported platform.

See https://github.com/vrza/node-blake2 for an alternative addon for BLAKE2 that also supports BLAKE2bp and BLAKE2sp, using the same reference implementation, and also providing the full streaming API to match the core 'crypto' hash API.

Use this implementation if you have simple needs, guaranteed Node.js usage (no browser), and don't need additional layers of fluff.

API

• blake2b(input:<Buffer>, key:<Buffer|null>, outputLength:number)
• blake2s(input:<Buffer>, key:<Buffer|null>, outputLength:number)

const { blake2b, blake2s } = require('@rvagg/blake2')

console.log(blake2b(Buffer.from('abc'), null, 64).toString('hex'))
// -> ba80a53f981c4d0d6a2797b69f12f6e94c212f14685ac4b74b12bb6fdbffa2d17d87c5392aab792dc252d5de4533cc9518d38aa8dbf1925ab92386edd4009923'

console.log(blake2b(Buffer.from('abc'), null, 64).toString('hex'))
// -> 508c5e8c327c14e2e1a72ba34eeb452f37458b209ed63a294d999b4c86675982
