If you use Keybase you can easily sign or encrypt things to me. The details are on my Keybase profile page.

If you would like to send me signed or encrypted stuff using GPG, below is my public key. You can also use gpg to import my public key directly from keys.openpgp.org using gpg --keyserver keys.openpgp.org --search CB4CFE7DF6F706FE5F4E15813BB81FB37ED71D98.
