Key Generator

A simple tool to generate and verify license keys for your app.

This app uses RSA signature verification to sign the email address of a user with a private key, then verify the signature with an associated public key.

Installation

From the Python Package Index:

pip install keygen-yocto

or from the source:

./setup.py install

Requirements

• Python

Usage

keygen

1. Generate a new pair of RSA keys.

   

   Note: You will only have to do this once.

2. When a user purchases a license, generate a license key and send it to the user.

   

   Note: Sales and Customer Service teams will only have to do this step. You will have to ship the private RSA key with this app to them.

3. In your app, verify that the license key is valid.

   from keygen import keys
   
   if keys.valid('email', 'license_key', 'public_key'):
       pass    # The license key is valid.
   else:
       pass    # The license key is invalid.

   Note: You will have to ship the public RSA key with your app.

Roadmap

1. Verify license keys in the GUI.
2. Show a list of license keys that was generated.
