GnuPG for Windows with Kleopatra
Gpg4win ranks #8 of 11 in File encryption tools, with an Alt Score of 55. It is licensed under GPL, donationware from Free and available on Windows. 9 of 9 checklist rows are verified against a public source.
Windows users and organizations who need to encrypt and digitally sign emails and files, particularly those already using Outlook or Windows Explorer for daily work.
Gpg4win is a free, open-source Windows installer package built around GnuPG. It bundles Kleopatra, a certificate and key manager for creating, importing, and managing OpenPGP and S/MIME keys; GpgOL, a plugin that adds encryption and signing to Microsoft Outlook; and GpgEX, a Windows Explorer context-menu extension for encrypting and signing files directly from the file system. Documentation (the Gpg4win Compendium) is included to guide setup and everyday use.
At its core is GnuPG, which implements the OpenPGP and S/MIME standards for public-key cryptography. Users generate or import key pairs in Kleopatra, then encrypt/decrypt and sign/verify emails via GpgOL or files via GpgEX, with GnuPG handling the underlying cryptographic operations.
