Issue/Introduction

 PGP Encryption Desktop (Symantec Encryption Desktop) has the ability to encrypt files.  You can encrypt one file by itself, or many files.  

The output could be one file, containing many files into one encrypted PGP file, or you can have one PGP encrypted file that decrypts one file.

This article will show you how to do this with macOS. 

To encrypt individual files with PGP Encryption Desktop on Windows (right-click, or drag-n-drop method), see the following article:
178739 - HOW TO: Encrypt Files and Folders with PGP Encryption Desktop for Windows (Symantec Encryption Desktop)


To encrypt files in an automated/scripted method, see the following article:

Resolution

There are multiple ways to encrypt and decrypt files using PGP Encryption Desktop.

PGP Zip allows you to put any combination of files and folders into a compressed and encrypted package for convenient transport or backup.

You can also encrypt individual files.
 

  • PGP Zip archives can be freely moved between a macOS system and Windows platforms, as long as PGP  Encryption Desktop is installed on the system to which the archive is being moved.

  • When you encrypt a file, you are creating a second copy of the file that is encrypted. The original still exists in its original location and remains unencrypted. The Output, or Encrypted files have a .pgp extension appended to the filename.


 

PGP Zip

Creating a PGP Zip: 
 

  1. Open PGP  Encryption Desktop by clicking on the PGP Desktop icon in the system menu bar, then scroll down and click Open PGP Desktop.

    If the PGP Desktop icon is not visible in the system menu then start PGP Desktop by clicking on the application (default location is the Applications folder).

  2. From the PGP menu, click File and then scroll to New and click PGP Zip from the sub-menu. The Untitled PGP Zip screen appears.

  3. Select the type of encryption. If you want to encrypt to the public key of specific recipients, click on the dot by to the following recipients. For encrypting to a passphrase, click on the dot beside with passphrase (no keys required) and go to step 4. To continue with a public key user, click on the +, select the public key of the person you wish to encrypt to, and click OK. Repeat this for adding multiple users. Skip to step 5.

  4. If you selected encrypting to a passphrase, click on Set Passphrase. Then enter and confirm a passphrase and click OK. This passphrase will be required in order to open the PGP Zip.

  5. If desired, you can specify a signing key from your private keyring allowing anyone opening the PGP Zip to verify that it was created by you. Use the up/down arrow to the right of Sign with Key to select a public key to sign to. Put a check in the box by Save Detached Signature File by clicking on it, if you wish to have a detached signature file created. If you do not wish to sign, select none.

  6. Now add files and/or folders by dragging them into the Files box, or by clicking on the +, browsing to the desired file or folder and clicking Add.

  7. Click Finish.

  8. The save dialog appears. Specify a name and location for the PGP Zip archive, then click Save.

  9. If you specified a signing key, you are prompted for the passphrase of the signing key. Enter the passphrase and then click OK.

 

Opening a PGP Zip Archive: 
 

  1. Use the Finder or other method to locate the PGP Zip file.
  2. Double click on it.
  3. If the PGP Zip archive was encrypted to your public key, you are prompted for the passphrase of your private key. Enter the passphrase and click OK.
  4. If the PGP Zip archive was encrypted to a passphrase, enter the passphrase and click OK.
  5. If the PGP Zip archive was also signed, a verification screen will appear displaying the results.
  6. A new folder is created (in the same location as the PGP Zip archive), that includes files and/or folders that were in the PGP Zip archive.
