Source

adler32-js

This is a coffee-script port of adler32.c from zlib, written by Mark Adler. Port by Jason Walton.

Installation

npm install --save adler32-js

Usage

adler32-js complies to the Hash interface from the node.js crypto package:

Adler32 = require('adler32-js');
hash = new Adler32();
hash.update('Hello world!');
console.log("Digest: ", hash.digest('hex'));

Unlike crypto Hash objects, Adler32 object can be recycled using the reset() method.

If you are after the raw integer value, you can also use:

hash = new Adler32();
hash.update('Hello world!');
console.log("Digest as int: ", hash.result());

Helper functions are also available for hashing strings, files, and streams:

Adler32.fromStream(stream, {encoding: 'hex'}, function(err, result) {
    console.log("Digest", result);
});

Adler32.fromFile('./foo.txt', {encoding: 'hex'}, function(err, result) {
    console.log("Digest", result);
});

result = Adler32.fromFileSync('./foo.txt', {encoding: 'hex'});

result = Adler32.fromString('Hello world!');
