LockFS
The idea is pleasantly pragmatic: encrypt each file independently so you never have to rewrite a giant container when adding or moving data — that genuinely simplifies backups across mixed storage. The repo feels like an MVP: a runnable jar and clear UX goals, but it omits crucial cryptography details (cipher choices, key derivation, filename/metadata leakage, threat model) and usage examples, so it’s useful in concept but needs more security documentation and benchmarks before I’d trust it with sensitive data.
