I modified ssl-cert-check this weekend to print the certificate issuer along with the certificate expiration date:
$ ssl-cert-check -s mail.prefetch.net -p 443 -i
Host Issuer Status Expires Days Left
----------------------------------- ----------------- -------- ----------- ---------
mail.prefetch.net:443 Equifax Secure In Valid Jun 20 2006 247
Hopefully this will make renewals easier for folks using ssl-cert-check.
