Pretty Good Privacy (PGP) Authentication

In an effort to assure ARIN customers that email messages from ARIN are genuine, all messages sent from hostmaster@arin.net are authenticated by the ARIN PGP key signature. To authenticate ARIN emails you will need PGP software. Many examples of PGP software are available online for free.

Frequently Asked Questions about PGP

I have a key from hostmaster@internic.net. Why am I seeing an “invalid signature” error?

There are known cases where email exchange and virus-checking programs rewrite part of the message that the PGP key signature covers. To address this problem, speak to your vendor about how they might prevent changing or rewriting PGP-signed email messages.

Why are some PGP signatures in-line while others are attached?

PGP signing of email messages is being rolled out in phases, the end of which will result in all PGP-signed messages being RFC 3156 compliant.
