In their own words
Encryptomatic OpenPGP
Encryptomatic OpenPGP is a Windows application for encrypting and signing messages and files, with Outlook integration. Encryption happens locally on the PC, and messages remain protected end-to-end from sender to recipient; recipients need OpenPGP software to decrypt them. Files can also be encrypted or signed from the Windows right-click context menu. The software supports Windows 10 and 11, plus listed Classic Outlook versions from 2013 through Microsoft 365 in 32-bit or 64-bit editions. PGP key-server support covers key sharing, discovery, and revocation, including MIT.EDU. Administrators can customize the interface and deploy through MSI silent installation and registration; some shared environments can use activation-free enterprise versions. Personal users, nonprofits, activists, and individual journalists can use it free, while for-profit business domains require a license. Business and free editions have identical encryption capabilities. Business pricing starts at $29.99 a year for one license; Mac is not supported.
