I am Hanno Böck, a freelance journalist and IT security professional.

I am passionate about free and open source software, and have created a number of open source security tools.

I am currently primarily working on badkeys, a tool to detect cryptographic public keys with known vulnerabilities. Its code can be found here.

You may also want to check out snallygaster, a tool to scan web servers for files that should not be public, and freewvs, a tool to scan web roots for web applications with known vulnerabilities.

I am publishing the Industry Decarbonization Newsletter about cleantech and climate solutions.
