Werner Koch

Werner Koch is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Werner Koch rather than just read about it. In short: Werner Koch (born July 11, 1961) is a German free software developer. He is best known as the principal author of the GNU Privacy Guard (GnuPG or GPG).

Key takeaways

Werner Koch belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Werner Koch to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Werner Koch from memory before moving on to harder problems.

Reference excerpt

Werner Koch (born July 11, 1961) is a German free software developer. He is best known as the principal author of the GNU Privacy Guard (GnuPG or GPG). He was also Head of Office and German Vice-Chancellor of the Free Software Foundation Europe. He is the winner of Award for the Advancement of Free Software in 2015 for founding GnuPG. Journalists and security professionals rely on GnuPG, and Edward Snowden used it to evade monitoring whilst he leaked classified information from the United States National Security Agency.

Life and work Koch lives in Erkrath, near Düsseldorf, Germany. He began writing GNU Privacy Guard in 1997, inspired by attending a talk by Richard Stallman who made a call for someone to write a replacement for Phil Zimmermann's Pretty Good Privacy (PGP) which was subject to U.S. export restrictions. The first release of GNU Privacy Guard was in 1999 and it went on to become the basis for most of the popular email encryption programs: GPGTools, Enigmail, and Koch's own Gpg4win, the primary free encryption program for Microsoft Windows. In 1999 Koch, via the German Unix User Group which he served on the board of, received a grant of 318,000 Deutsche Mark (about US$170,000) from the German Federal Ministry of Economics and Technology to make GPG compatible with Microsoft Windows. In 2005 he received a contract from the German government to support the development of S/MIME. Journalists and security professionals rely on GnuPG, and Edward Snowden used it to evade monitoring whilst he leaked classified information from the U.S. National Security Agency. Despite GnuPG's popularity, Koch has struggled to survive financially, earning about $25,000 per year since 2001 and thus considered abandoning the project and taking a better paying programming job. However, given Snowden's leaked documents showed the extent of NSA surveillance, Koch continued. In 2014 he held a funding drive and in response received $137,000 in donations from the public, and Facebook and Stripe each pledged to annually donate $50,000 to GPG development. Unrelated, in 2015 Koch was also awarded a one-time grant of $60,000 from the Linux Foundation's Core Infrastructure Initiative.

Worked examples

Example 1 — a first encounter with Werner Koch

Start with the simplest possible case. Write down what Werner Koch claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Werner Koch before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Werner Koch ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Werner Koch

In research: Werner Koch appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Werner Koch in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Werner Koch is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 births, Cypherpunks, Free software programmers, so understanding it makes those chapters shorter.
In everyday life: Look for Werner Koch outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
