Fernet (Pure Python Implementation)

This `fernet` library provides a simple, pure Python implementation of the Fernet symmetric encryption specification. Unlike the `cryptography.fernet` module, this package does not rely on C extensions, making it suitable for environments where C-based compiled modules are undesirable or for use as a simple reference. However, it is explicitly *not recommended* for production or security-sensitive applications due to its age and lack of active maintenance compared to the `cryptography` library's implementation. It was last updated in 2016.
