keys
Below is linked my PGP public key. It's also linked on the front page and at the footer of every other page. With it you can verify my digital signature on emails, git commits, etc. and also send me encrypted email and files. If you don't know how to use PGP or what it is, I recommend this article by Varonis.
Following are old keys which are no longer in use. Public key and revocation certificate are linked, as well as revocation date. Use the public key to validate signatures from before the revocation date only!
