🔐 ForgetNot — Command-Line Password Manager (C)

ForgetNot is a terminal-based password manager written in C that allows users to generate, store, view, edit, and delete passwords using binary file storage.
The project focuses on low-level systems concepts such as memory management, binary I/O, and modular program design.

  • User-defined length
  • Optional symbols
  • Randomized using rand() seeded with system time

• 💾 Binary File Storage

  • Passwords stored securely in a binary file (passwords.db)
