Is there such thing as a multihost security certiciate? Here's what I
want to do: I have several domains (mydomain1.com, mydomain2.com,
mydomain3.com) all pointed at the same IP. We are running an Apache 2
web server on some kind of Linux system. Since Apache can only
install one security certificate, it would be great if that cert could
represent the three different domains and be from a trusted certiciate
Does anyone know of any?
Thanks, - Dave
Re: Is there such thing as a multi-host security certificate?
If you were talking about mutiple hostnames within a single domain ie
myhost1.mydomain.com, myhost2.mydomain.com, myhost3.mydomain.com
then you could get a wildcard certificate for mydomain.com.
In this case it looks like the only solution would be to request a
certificate utilising the SubjectAltName extension
For an example extract from an openssl config file see
which shows the SubjectAltname setup for a certificate for www.acme.com,
It appears that Entrust supports SubjectAltName certificates for this purpose
(though possibly only one extra name) with their Advantage certificates
Other trusted CAs may now be starting to support the SubjectAltName extension.
