Basalt 1.0
Security-hardened TrueCrypt 7.1a fork for macOS.
Features:
- Argon2id key derivation (1 GB memory cost, 8 threads) — GPU-resistant by design
- Opens TrueCrypt 7.1a & VeraCrypt volumes, with automatic KDF upgrade prompt
- Hidden volumes with plausible deniability and outer volume write protection
- Native SwiftUI app — no wxWidgets, no Qt, clean dark-mode interface
- DarwinFUSE built-in — no macFUSE, no kernel extension, no SIP changes
- Zero-state design — no password cache, no favorites, no history
- Auto-dismount on inactivity, screen lock, sleep, quit, and logout
- Screen capture protection (invisible to screenshots, recording, AirPlay)
