Generate Google ID Token

This tool allows the generation of a Google ID Token from a service account json key. Such token can be used for authentication in GCP API Gateway and Cloud Endpoints. A valid token represents a legitimate service account.

Generating the token has two phases:

• Generating a self-signed JWT with the service account private key.
• Using the JWT to call OAuth2 Google endpoint to generate a token.
