My public GPG key can be found here. I will be signing my CTF files so you can verify they have come from me. Feel free to use my public key if you wish to send me any messages.
I recommend getting my key from this website as I cannot guarantee key servers are kept up-to-date. This is with the exception of PGP Global Directory who perform e-mail verification on new keys/key changes. I will make an effort to keep this server up-to-date.
