Frequently Asked Questions

Q: Is my passphrase stored anywhere?
A: No, your passphrase is only used during the encryption/decryption process and is not stored.

Q: Can I use this on macOS?
A: Yes, but you'll need to install the prerequisites using Homebrew: brew install gpg zip p7zip

Q: What if I forget my passphrase?
A: Unfortunately, without the passphrase, your encrypted data cannot be recovered. Always keep your passphrase secure.

Q: Can I encrypt individual files?
A: Currently, the tool only supports encrypting folders. You can place individual files in a folder first.

Troubleshooting

Error: "Missing required packages"
Solution: Install the missing packages listed in the error message.

Error: "Decryption failed"
Solution: Check that you're using the correct passphrase and that the file wasn't corrupted.
