metrohash

node-metrohash

Wrapper around MetroHash.

Installation

$ npm install metrohash

Usage

The module exports 2 classes, MetroHash64 and MetroHash128.

Both have the same interface:

// Constructor.
Hash([ seed:Number = 0 ]) : Object

// Update.
Hash#update(input : [String | Buffer]) : void

// Finalize and get hash digest.
Hash#digest() : Buffer

// One-shot: hash input and return digest.
Hash#hash(input : [String | Buffer]) : Buffer

Examples

var MetroHash64 = require('metrohash').MetroHash64;

// Instantiate using seed 123 (`new` is optional).
var hash = new MetroHash64(123);

// Update using a string as input.
hash.update('Hello, World!');

// The same as above:
// hash.update('Hello, ').update('World!');

// Finalize and convert to hex string.
var digest = hash.digest().toString('hex');

// Or as one-shot:
var digest = MetroHash64(123).hash('Hello, World!').toString('hex');
