A certificate is valid as long as the CA that vouches for the DN renews the certificate. They keys can be renewed, and algorithms can even be replaced. That's the payoff from the overhead of the PKI. => This is what we need to capture into the document. A public key has no expiry date, since it has no date associated with it. When you say that a public key is "typically" shorter, you are really expressing a good crypto-hygiene suggestion to the owner of the public. -- Michael Richardson <mcr+IETF@sandelman.ca>, Sandelman Software Works -= IPv6 IoT consulting =-
