# About

Hi! I'm Jesper. You've found the place where I advertise my current set of crypto keys and fingerprints.

## Key signing policy

I will sign your PGP key if you ask me to, and I have somehow verified that the identity of the key matches your
identity. I will probably also ask you to sign my key.
