Unless prior arrangements have been made, all requests will be signed by our testCA which as described in help/certs can be used to obtain limtited numbers of testing certificates to facilitate use of SSLrsh and similar SSL based tools.
You can obtain our CA cert and current? CRL via ftp. You can also grab revoked.cert to see how a revoked certificate is handled.
Some browsers will not display a secure form unless they know the CA that issued the host's certificate. If you are thus aflicted, you can click here to teach your browser about our CA cert. after which (and a possible browser restart) it will happily accept certificates signed by us.
