JSON Web Token (JWT) Bearer Token Exchange Middleware for OAuth2orize.
This module exchanges a JWT for an access token after authenticated, as defined by the JSON Web Token (JWT) Bearer Token Profiles for OAuth 2.0 draft. This module is modeled off of Google's OAuth 2.0 Server to Server Applications. This module can be used with the passport-oauth2-jwt-bearer module to create a JWT OAuth 2.0 exchange scenario server.
$ npm install oauth2orize-jwt-bearer
This exchange middleware is used to by clients to request an access token by using a JSON Web Token (JWT) generated by the client and verified by a Public Key stored on the OAuth 2.0 server. The exchange requires a verify callback, which accepts the client, JWT data and signature, then calls done providing a access token.
var jwtBearer = require('oauth2orize-jwt-bearer').Exchange;
server.exchange('urn:ietf:params:oauth:grant-type:jwt-bearer', jwtBearer(function(client, data, signature, done) {
var crypto = require('crypto')
, pub = pubKey // TODO - Load your pubKey registered to the client from the file system or database
, verifier = crypto.createVerify("RSA-SHA256");
verifier.update(JSON.stringify(data));
if (verifier.verify(pub, signature, 'base64')) {
// TODO - base64url decode data then verify client_id, scope and expiration are valid
AccessToken.create(client, scope, function(err, accessToken) {
if (err) { return done(err); }
done(null, accessToken);
});
}
}));
