Starlette CSRF Middleware

Starlette-CSRF is an active Python middleware designed for Starlette and FastAPI applications to mitigate Cross-Site Request Forgery (CSRF) attacks. It implements the Double Submit Cookie technique, providing protection by requiring a secret value to be sent in both a cookie and a request header for unsafe HTTP methods. The library is currently at version 3.0.0 and maintains a steady release cadence, with the latest major update focusing on Python version compatibility and argument handling.
