We have been working for you for over 20 years on the following:
Although cryptography has its roots in abstract mathematics, its proper usage always comes with huge real-world impact on mitigating the risks of business operation problems and monetary damages.
Information security management includes the necessity to regularly test the systems and infrastructure security. Security auditing and penetration testing is used for performing such regular testing.
Professional analysis and viable design and implementation of specialized software or secure server and network infrastructure are the key components for success of new and current services no matter the scale.

Originally working on a YubiKey support for Crypt4GH stream processing library turned out to become a work to fully support GnuPG at least on UNIX platforms. In recent GnuPG versions everything is handled by gpg-agent but an interesting problem arose - how to find its socket when using alternative GnuPG homedir?

Analyzing cryptographic systems usage with respect to how the users interact with it sometimes requires programmatically simulating their actions. It is no different with our recent work on rclone cryptographic keys handling. However we are lucky that Racket provides all the functionality we needed!

Faced with the requirement of computing symmetric key from the result of Elliptic-Curve Diffie-Hellman key exchange according to a specification, the primary ingredient for such calculation is the result itself. Read on to see how Interesting things you may find if you need to use YubiKey's OpenPGP Card application as a foundational component of any solution.
