MiniVault - Offline Password Manager in C

Hi! This is MiniVault — a tiny offline password manager built in pure C.

On launch, it checks for my passwords dat. No file? It simply starts

empty. Menu: 1 Add, 2 Show, 3 Save and

Exit, 4 Exit without saving. Let’s add one. Site:

github.com. Username: mygithubuser. Password: My Super Secret

1 2 3! The password is instantly XOR-obfuscated in memory with a

fixed key for basic protection. Press 2 to view. It temporarily decrypts

a copy for display while the original stays protected. Choose 3 to save.
