node-http-signature

node-http-signature is a node.js library that has client and server components for Joyent's HTTP Signature Scheme.

# Usage

Note the example below signs a request with the same key/cert used to start an HTTP server. This is almost certainly not what you actually want, but is just used to illustrate the API calls; you will need to provide your own key management in addition to this library.

## Client

var fs = require('fs');
var https = require('https');
var httpSignature = require('http-signature');
var key = fs.readFileSync('./key.pem', 'ascii');
var options = {
host: 'localhost',
port: 8443,
path: '/',
method: 'GET',
headers: {}
};
// Adds a 'Date' header in, signs it, and adds the
// 'Authorization' header in.
var req = https.request(options, function(res) {
console.log(res.statusCode);
});
httpSignature.sign(req, {
key: key,
keyId: './cert.pem'
});
req.end();

## Server

var fs = require('fs');
var https = require('https');
var httpSignature = require('http-signature');
var options = {
key: fs.readFileSync('./key.pem'),
cert: fs.readFileSync('./cert.pem')
};
https.createServer(options, function (req, res) {
var rc = 200;
var parsed = httpSignature.parseRequest(req);
var pub = fs.readFileSync(parsed.keyId, 'ascii');
if (!httpSignature.verifySignature(parsed, pub))
rc = 401;
res.writeHead(rc);
res.end();
}).listen(8443);
