Troubleshooting DeadBolt File Encryptor: Common Issues and Fixes

Step-by-step setup: Using Deadbolt File Encryptor for strong encryption

1) Install Deadbolt

• macOS: Homebrew — brew install deadbolt –cask, or download the .dmg from Releases and drag to Applications (run xattr -c /Applications/Deadbolt.app if macOS blocks it).
• Windows: Download the installer from the GitHub Releases page and run it.
• Linux: Use the AppImage or Flatpak from Releases.

2) Launch the app (GUI) or install CLI

• GUI: Open the Deadbolt app from Applications / Start Menu.
• CLI: clone & install:

Code
Copy CodeCopied
git clone https://github.com/alichtman/deadbolt.git && cd deadbolt npm run install:cli 

3) Prepare files/folders

• Choose the file(s) or folder(s) you want encrypted. Make a backup copy if you need a plaintext archive before encrypting.

4) Encrypt (GUI)

1. Click “Encrypt”.
2. Select file or folder.
3. Enter a strong password (see passphrase tips below).
4. Confirm and wait; encrypted file(s) get a .deadbolt extension.

5) Encrypt (CLI)

• Encrypt a file:

Code
Copy CodeCopied
deadbolt encrypt /path/to/file.pdf 

• Optional (not recommended for security): pass password on command line:

Code
Copy CodeCopied
deadbolt encrypt secret.pdf –password “your-password” 

6) Decrypt (GUI)

• Open Deadbolt, choose “Decrypt”, select the .deadbolt file, enter the password, and restore the original file.

7) Decrypt (CLI)

Code
Copy CodeCopied
deadbolt decrypt secret.pdf.deadbolt # or with password (warning: may be logged) deadbolt decrypt secret.pdf.deadbolt –password “your-password” 

8) Recommended password/passphrase practices

• Use a long passphrase (12+ characters) with mixed words, or a 20+ character random password.
• Avoid passing passwords on command line to prevent shell-history leaks.
• Store passwords in a reputable password manager.
• If you need sharing, exchange passphrases securely (out-of-band).

9) Cross-platform notes

• Deadbolt-encrypted files are interoperable across macOS, Windows, Linux.
• To set Deadbolt as default for .deadbolt files on macOS, use duti (example in repo docs).

10) Security notes (practical)

• Keep Deadbolt updated (check Releases).
• Keep OS and antivirus up to date.
• Maintain offline backups — encrypted files should not be the only copy.
• Verify downloaded binaries from the GitHub Releases page.
