Components of Gpg4win

During the process of installation, you’re going to come across a selection of components[2] you may or may not want to install. Here’s what they are for:

  • gnuPG – the core piece of software (you have to install this one),
  • Kleopatra – keyring manager useful for various operations with keys,
  • GPA – GNU privacy assistant – alternative to Kleopatra,
  • gpgOL – plugin for Outlook email client,
  • gpgEX – shell extension which enables you to encrypt or sign files right from the context menu in Windows Explorer,
  • Browser integration – enables Mailvelope browser extension support.

Out of this list, we want to install GpgOL as it adds the options of encryption, decryption and signing to your Outlook e-mail client. We also want to install Kleopatra as it’s the best for managing public keys of people you want to securely communicate with. The rest is up to you.

  1. Open the installation file

  6. Proceed with Install (the installation may take few minutes)
