Instructions of the file decryption with PGP

Step 1: Ensure that you have all required tools

To decrypt a file you will need to have a PGP client. There are some popular PGP clients:
  • GnuPG (GPG): free and popular utility to work with PGP.
  • PGP Desktop or Kleopatra: GUI interfaces to work with PGP on Windows.
  • GPG Suite: for macOS.

Step 2: Ensure that you have the following components

  • The file you need to decrypt (eg. file.pgp or file.gpg).
  • Private key (it should be imported into your PGP client).
  • Password (passphrase) if it was set for the private key.

Step 3: Import a private key into your PGP client (if you haven't done it before)

If you're using GnuPG run the following command in the terminal: gpg --import your-private-key.asc Replace your-private-key.asc with the name of the file with your private key.

Step 4: Decrypt a file

  • Through the terminal (GPG):

    Run the following command: gpg --output decrypted-file.txt --decrypt file.pgp
    • file.pgp — encrypted file you want to decrypt.
    • decrypted-file.txt — filename the decrypted content will be saved to.
    If your private key is protected with a password you'll need to enter it for decryption.
  • Through a GUI:
    • Open an app eg. Kleopatra (on Windows) or GPG Suite (on macOS).
    • Choose an option to decrypt/check the file.
    • Choose the path for the encrypted file and follow the instruction in app.
    • Enter the password (if it was set) and wait for the decryption process will be finished.

Step 5: Check the result

  • After a successful decryption you'll get a file with a readable content.
  • Ensure that the file is located in a right place and has an expected content.

Notes
  • Ensure that your private key is stored in a secure place and don't give it to anyone.
  • If you're using a password for your private key choose strong and unique password to increase protected.
