In this file, I declare that the PGP key I currently use to sign pictures on FITstagram is mine.

This file is signed with my other, more trustworthy identity. It carries a certificate issued to me by the Czech PostSignum authority. According to the European regulation eIDAS, it has the equivalent legal effect as a handwritten signature.
