Encrypting & Decrypting Files

Necron Vault Manager offers two ways to encrypt and decrypt your files: vault-based operations (adding files to an organized vault) and standalone Quick Encrypt/Decrypt (for quick, one-off operations without setting up a vault).

Encrypting Files into a Vault

The primary way to encrypt files is by importing them into a vault:

1. Select a vault — click a vault in the sidebar to make it active
2. Add files — click ADD FILES in the toolbar to select files, or ADD FOLDER to add an entire directory
3. Done — files are automatically encrypted and stored across all your vault locations

The vault browser updates in real-time as files are imported. A progress overlay appears during large imports.

Decrypting Files from a Vault

To decrypt files stored in a vault:

1. Select files in the vault browser (use Ctrl+Click or Shift+Click for multiple files)
2. Click DECRYPT FILES in the toolbar

1. Choose a destination folder for the decrypted output
2. Files are decrypted and saved to your chosen location

Quick Encrypt (Standalone)

For encrypting files without adding them to a vault:

1. Click the Encrypt tile in the inspector footer (bottom of the right-hand panel)

1. Add files or folders using the buttons in the modal
2. Choose a destination — by default, encrypted files are saved next to the originals
3. Toggle options:
   • Encrypt filenames — hides original filenames for extra privacy
   • Create zip file — bundles multiple files into one encrypted package (great for sharing)
4. Click Encrypt to start

Each file shows its progress: pending → encrypting → done (or error details if something went wrong).

Output Files

Zip Archive Mode

When you have two or more files selected, you can enable Create zip file to bundle everything into a single encrypted package. This is especially handy for email or file-sharing — instead of sending 20 encrypted files, you send one.

Quick Decrypt (Standalone)

For decrypting files that aren't stored in a vault:

1. Click the Decrypt tile in the inspector footer
2. Add encrypted files (.ncrn files) or select a folder to find them automatically
3. Choose a destination — by default, decrypted files are saved next to the originals
4. Click Decrypt to start

The app automatically detects the encryption format, validates your key, decrypts the content, and restores the original filename.

Quick Encrypt vs. Vault Import

Error Handling

If a file fails during processing, the app continues with the remaining files — it doesn't stop the whole operation. Failed files show error details in their status.

Common issues:

Tips for Large Operations

• Close other disk-intensive programs to maximize performance
• Use a local destination rather than a network drive for better speed
• Monitor the capacity bar in the Key Drive status card when encrypting many files
• Review results carefully to catch any individual failures
