What it does

Gpg4win packages GnuPG-related tools for Windows file and email encryption, with an illustrated getting-started compendium.

Gpg4win provides a Windows starting point for encryption and key-management work that would otherwise require assembling individual components. Its official site points new users to the Compendium for the underlying workflow. Begin with a small file and a verified recipient key, and understand how the keys will be backed up before using the setup for irreplaceable material.
