A Certifier Process for BrowserID

This repository aims to build a process capable of signing certificates for BrowserID. If you wanted to build a Primary Identity Authority with BrowserID support, this is something you can run in your environment, and talk to over HTTP to implement certificate generation.

A Work In Progress.

Web Service API

The Certifier webservice provides the following API:

/cert_key

A request to /cert_key must

Be sent with the Content-Type of application/json
The POST message body should be a JSON formatted object which includes:
- email - The email address for this certificate
- duration - How long until the certificate expires, in seconds
- pubkey - Object compatible with JWT public keys.

The response will be:

Sent with the Content-Type of application/json
A JSON formatted object with includes:
- success - boolean indicating if the certificate was generated successfully
- certificate - string - A certificate compatible with navigator.id.registerCertificate from the BrowserID Provisioning Protocol

Dependencies

gmp.h - on Ubuntu this is the libgmp3-dev package
C++ compiler
make

Installation

Either npm or git should work:

npm install git@github.com:mozilla/browserid-certifier.git

git clone git://github.com/mozilla/browserid-certifier.git

You must install the dependencies:

cd browserid-certifier
npm install

You must create a config file. Example config/local.json

{
  "ip": "127.0.0.1",
  "port": 8080,
  "issuer_hostname": "dev.bigtent.mozilla.org",
  "pub_key_path": "var/key.publickey",
  "priv_key_path": "var/key.secretkey"
}

For maximum security, the above configuration makes the server only listen locally (on 127.0.0.1).

If you need the certifier to be accessible over the network, consider changing to something else, or listen on every IP (with “0.0.0.0”), provided you protect it by other means.

Generating the Keypar

Both your IdP service and the Certifier must share a public key. The Certifier, requires both a private and public keypair.

Do the following:

mkdir var
cd var/
../node_modules/.bin/generate-keypair
ls

You should now see a key.publickey and key.secretkey in the directory. This matches your local.json config.

You’ll also want to import or re-use this key.publickey in your IdP’s /.well-known/browserid file.

cd ..
./scripts/gen_well_known_browserid.py var/key.publickey > /some/path/www/.well-known/browserid

Running Certifier

CONFIG_FILES=config/local.json npm start
