Hashlib

Is a FAST nodejs(http://github.com/ry/node/) library for making hashes written in C/C++

Supports: md4, md5, md6, sha, sha1, sha256, sha512, hmac_sha1, hmac_md5, also can make md5 hash of files

Thangs to Vanilla Hsu for speed improvements and md4, sha support

Install:

way 1

1. go to the directory with hashlib library

2. execute node-waf configure build

3. get module from ./build/default/hashlib.node

You should use var hashlib = require("./build/default/hashlib"); (way to module)

way 2 (works if node are installed in default path)

1. go to the directory with hashlib library

2. execute make

3. execute sudo make install

You should use var hashlib = require("hashlib"); (from any path)

Functions:

md4(str); // Returns md4 hash from string
md5(str); // Returns md5 hash from string
sha(str); // Returns sha hash from string
sha1(str); // Returns sha1 hash from string
sha256(str); // Returns sha256 hash from string
sha512(str); // Returns sha512 hash from string
md6(str[, length]); // Returns md6 hash from string, second parametr is optional
md5_file(path[, callback]); // Returns md5 hash from file callback is optional and works async
hmac_sha1(str, key) // Returns hmac sha1 hash with an key
hmac_md5(str, key) // Returns hmac md5 hash with an key

Usage:

var hashlib = require('hashlib');
hashlib.md5('text');

Speed testing

To run speed test on your computer run test.js, here is my: C++ md5 result is: 220 JS md5 result is: 5660 C++ module faster than JS in 25.727272727272727 times ----------- C++ md4 result is: 212 C++ md6 result is: 3889 C++ sha0 result is: 228 C++ sha1 result is: 495 C++ sha256 result is: 712 C++ sha512 result is: 612
