ISC and OpenPGP

ISC has an OpenPGP key. You can learn more about OpenPGP in RFC 2440. OpenPGP is a public key system, which means that if you have our public key and we sign a mail message (or a software distribution) using our private key, you can have a moderate confidence level that the message or distribution really did come from us.
