Questions

How secure is it?

Files are encrypted with AES-256-GCM. The key is derived from your password with PBKDF2-SHA-256 (600,000 iterations) and a random salt. A strong password is what keeps it safe.

I forgot my password. Can you recover the file?

No. Nothing is stored anywhere, so a lost password means the file cannot be decrypted.

How do I decrypt?

Drop the .lkenc file here and enter the same password. The original file name is restored.
