Twofish Python Bindings

The `twofish` library provides Python bindings for a C implementation of the Twofish symmetric key block cipher, designed by Niels Ferguson. Twofish is a 128-bit block cipher supporting key sizes up to 256 bits, and was a finalist in the AES competition. The current version is 0.3.0, with the last PyPI release in 2013, and the official GitHub repository was archived in January 2025, indicating it is no longer actively maintained.
