LockFS is a flexible file-by-file encryption for secure storage

Encrypts files one-by-one from a single runnable JAR, which is nice for cross-platform use and managing many small vaults without re-archiving. The README clearly explains usage, but there’s no visible discussion of algorithms, key management, integrity guarantees, or threat model — that omission keeps this from standing out in a space already served by mature tools like age/gocryptfs.
