I'm 99.999% I know the answer to this but I just want to confirm it first. When installing a wildcard SSL certificate you generate a CSR before doing so correct? You cant have a Generic wildcard SSL to install on multiple servers? Head office have sent over a wildcard certificate and a intermediate certificate and when comparing a MD5 hash of the public key for the wildcard I get a mismatch: CERT: (stdin)= 233918fe403cd5acc3f3277a3b7a8de3 Server Key (stdin)= 1601c3c9e99514ac5ea169145e3ef3ea It came over as a .P7B file and I converted it to a PEM file using the following command: I'm then using this cert in my httpd_VHOST config in Apache. I plan on having multi sites on this server all using the wild card cert, is there a way to make a blanket config change to secure the sites using the one cert or must I comment in the SSL config for each VHOST?
