If you'd like to send me a super-secret message, my PGP public key is now available for download here. You can also import it directly by running
curl https://jonathanthom.com/jonathanthom.asc | gpg --import, or find it on my contact page.
The key's fingerprint is: 2234 2499 516C 6C96 EF0E E053 AC35 0024 11C3 7541
A fun practical use for PGP (not saying other uses are not practical...) is to start signing your GitHub commits.
