Is there an easy way to determine the expiration date of an RSA key
pair? I know that I can change the public key and propagate it to the
appropriate servers, but I'd like to avoid this if at all possible.

a point of clarification: I mean the DSA private/public key pair used
for ssh.

For OpenSSH, there's no certificate authority to enforce any key
expiration. So keys generally do not expire.

It's possible to use Tectia SSH with a CA, so I think that supports key
expiration/revocation, but I'm unfamiliar with it.
