is a lightweight, high-security file encryption tool designed for absolute simplicity and portability. While the original project was archived by its creator in August 2025, it remains a gold standard for "no-nonsense" privacy enthusiasts.

: A unique "paranoid mode" feature that adds redundant data to files, allowing them to be recovered even if the encrypted volume suffers minor data corruption (e.g., from bit rot on a USB drive). The "State of the Union": Development Status
