node-crypto
===========
A wrapper around openssl for node.js, currently exposing Hashing, Signing
and Verifying methods.
To install, ensure that you have openssl installed, and run:
node-waf configure
node-waf build
This will put the crypto.node binary module in build/default.
The hashing, signing and verifying methods can work with binary, hex or
base64 encoded strings.
Quick example
-------------
var sys=require("sys");
var posix=require('posix');
var crypto=require("./crypto");
// Test hashing
var h1 = (new crypto.Hash).init("sha1").update("Test123").digest("hex");
var h2 = (new crypto.Hash).init("sha1").update("Test").update("123").digest("hex");
sys.puts(h1===h2);
// Load our public and private keys
var keyPem = posix.cat("test_key.pem").wait();
var certPem = posix.cat("test_cert.pem").wait();
// Test signing and verifying
var s1 = (new crypto.Sign).init("RSA-SHA256").update("Test123").sign(keyPem, "base64");
sys.puts((new crypto.Verify).init("RSA-SHA256").update("Test").update("123").verify(certPem, s1, "base64"));
