Portable Vault Encryptor

A portable authenticated encryption vault manager (.pvault containers) for Linux USB flash drives, external SSDs, SD cards, and local directories.
A lightweight Linux alternative to USBCrypt for protecting sensitive files on removable drives without requiring root privileges or disk reformatting.

Key features:
- Genuine authenticated encryption powered by OpenSSL libcrypto.so.3 (EVPaes256_gcm) with unique 96-bit CSPRNG nonces and 128-bit GCM authentication tags per object.
- Strong password key derivation using PBKDF2-HMAC-SHA256 (200,000 iterations, 128-bit random salt) wrapping a 256-bit vault master key for instant atomic password rotation.
- Create, inspect, lock/unlock, add files or folders, extract selected or all files, and run non-destructive GCM authentication tag verification across all vault blocks.
- Built-in multi-pass fsynced plaintext file shredder (1-pass, 3-pass, and 5-pass CSPRNG overwrite) to wipe unencrypted source files after vault import.
