crc32c

Node-crc32c

Basic C modules for NodeJS with crc32c (Castagnoli) implementation for Linux. The implementation uses the native Linux library "AF_ALG".

This module is not meant for secure hashing but really for something like ETags or anything that is easier to compare using a hash than the full string.

##Building

node-gyp configure build

or

npm install crc32c

##Usage

From JavaScript:

var crc32c = require('crc32c');

// Works with strings!
var toHash = "HELLOWORLD";
console.log(crc32c.compute(toHash));

// Or buffers!
console.log(crc32c.compute(new Buffer('{"jsonString":"property1","jsonArray":["arr1","arr2","arr3"]}')));

From cli:

crc32c <filename>

It currently supports only one file at the time.
