Digital Signature with hmac SHA256 implemented with python3

HMAC Implementation Example and Explanation

A secure multi-user file system with end-to-end encryption, HMAC-based integrity verification, and Unix-style permission control. Features bcrypt-authenticated logins, group-based collaboration, and a command-line interface for secure file operations on untrusted storage.
