The creation of GNU Privacy Guard in 1997 provided a critical tool for journalists and security professionals seeking to bypass unauthorized monitoring. Developed by Werner Koch in Germany, this software emerged as the primary alternative to existing cryptographic programs hampered by U.S. export restrictions, eventually serving as the foundational architecture for widespread email encryption technologies globally.
Early Development and Objectives
Born in 1961 in Düsseldorf, Germany, Werner Koch established himself as an engineer, computer scientist, mathematician, and cryptographer within the free software movement. Following a presentation by Richard Stallman, Koch initiated the development of GNU Privacy Guard, intending to build a functional replacement for Phil Zimmermann’s Pretty Good Privacy. By 1999, the first version of the software was released, providing a platform that later enabled projects such as Gpg4win, GPGTools, and Enigmail.

The evolution of the project was supported by several financial grants. In 1999, Koch secured 318,000 Deutsche Mark—approximately US$170,000—via the German Unix User Group from the German Federal Ministry of Economics and Technology to ensure compatibility with Microsoft Windows. By 2005, he received a further government contract to develop S/MIME capabilities. Despite these grants, Koch maintained a modest personal income, reported at roughly $25,000 annually since 2001.
Public Funding and Continued Maintenance
The operational future of GnuPG faced uncertainty until 2014, when public documentation regarding United States National Security Agency surveillance practices prompted a reassessment of the project's utility. A 2014 fundraising campaign generated $137,000 in public donations, while Facebook and Stripe committed annual contributions of $50,000 each. Additionally, the Linux Foundation's Core Infrastructure Initiative provided a $60,000 grant in 2015. Koch continues to serve as the maintainer of the project, a role he has held since 1997.
