Keys

Secure Email

For secure email, I use GnuPG/OpenPGP; if you wish to send me encrypted email, please use my public key from the keyservers. Please be sure to verify the fingerprint! If you’re really paranoid, and want to be absolutely sure this is me, get in touch with me offline.

  • Key ID: C44F0EA9

Secure Sites

Various websites I maintain use SSL encryption; all site certificates are issued by my self-signed root CA. In order to be sure that the secure websites you are connecting to are really mine, and also to avoid the certificate warnings, please install my root certificate below. Please be sure to verify the fingerprint! If you’re paranoid, and want to be absolutely sure this has not been tampered with, I keep a printed version in my office.
