Manages encoding/decoding of any payload data.

You can dynamically refer to the key used to encode/decode through the use of secret_key_env_variable_name. By default, the key used is JWT_MANAGER_SHARED_SECRET.

Usage:
Add an environment variable to your stack, with the JWT shared secret. Use this variable's name to initialize the JWT Manager:

Encoding
manager = JwtManager.new('INTEGRATION_JWT_TOKEN')
payload = { a: 1, b: 2 }
token = manager.encode(payload)

Decoding
manager.decode(token)
