Authentication Microservice

This is a gRPC-based authentication microservice written in Python. It provides functionality for user sign-in, token authentication, token refresh, and logout operations. The service uses Redis for storing refresh tokens and maintaining a token blacklist, with JWT (JSON Web Tokens) for secure access tokens.

Features

• SignIn: Authenticate a user and issue access and refresh tokens.
• Authenticate: Validate an access token and retrieve the associated username.
• RefreshToken: Generate new access and refresh tokens using a valid refresh token.
• Logout: Invalidate access and refresh tokens by adding them to a blacklist.
• Token Blacklist: Invalidated tokens are stored in Redis to prevent reuse.
• Redis Integration: Refresh tokens and blacklists are stored in Redis with TTL.
• gRPC: High-performance RPC framework for efficient communication.

Requirements

• Python 3.10+
• Redis
• Docker (compose v2)
