Passwords and Encryption in ZipGood
Short answer: ZipGood stores passwords exclusively in the macOS Keychain. A default password enables one-click encryption from the Finder, and a password book holds a list of passwords that ZipGood tries silently when opening encrypted archives.
Default password
Set a default password in Settings → Password. It is stored in the macOS Keychain and can be tried automatically on encrypted archives, or used for one-click encryption from the Finder.
Password book
The password book is a list of passwords, also stored in the Keychain, that ZipGood tries silently before prompting you. This is useful if you receive encrypted archives from several different sources.
Where passwords are stored
Passwords are never written to disk and never sent anywhere — they never leave the macOS Keychain.
Encryption support
- AES-256 encryption for 7z archives, with optional header encryption
- AES-256 encryption for ZIP archives
- Encrypted DMG disk images
