Overview

The code in this folder provides examples for creating a Layer Identity Token for both the Flask and Django web frameworks.

Each example shows how to create an endpoint, identity_token, that requires the following parameters:

  • user_id: The user ID of the user you want to authenticate.
  • nonce: The nonce you receive from Layer. See docs for more info.

Response

Upon success, the endpoint will return a JSON object that contains a single key, identity_token. If the required input parameters were not provided, the endpoint will respond with "Invalid response."

Example successful response:

{
"identity_token": "eyJ0eXAiOiJKV1Mi..."
}

Python setup

For both examples, you need to first install the required Python libraries:

  • PyJWT - The officially supported JWT library for Python
  • pycrypto - Provides RSA signing capabilities for PyJWT

To install these modules, run the following command:

pip install -r requirements.txt

Note: the pip command may be pip3 if you are running Python 3.0+.

Configure your Layer app

To run either example, there are 3 constants that you should set in layer.py, all of which are available in the Keys section of the Layer dashboard for your app.

  • PROVIDER_ID - Provider ID found in the Layer Dashboard under "Keys"
  • KEY_ID - Public key generated and stored in the Layer Dashboard under "Keys"
  • RSA_KEY_PATH - Path to the file containing the private key associated with the public key
