Recently I had a need to have a SSL certificate which should be used in multiple domains. When I search on that I found that it can be done using Unified Communications Certificates (UUC) :
This is how I generated a multidomain certificate request :
1. Open openssl.cnf
2. Make sure following line are there in that file :
[req]
req_extensions = v3_req
[v3_req]
subjectAltName = @alt_names
[alt_names]
DNS.1 = example.com
DNS.2 = hello.example.com
DNS.3 = testing.com
You should add your domains as given in under [alt_names]
3. Create a private key
4. generate your certificate requests by providing required information
Thats all! you are done!!!

You can make sure by
openssl req -text -noout -in ssl.csr
Under the alternative section you can find your all the domains listed.

Its clean and straight forward guidance about self signed certifiable. Being Platinum Certificate Authority that we wish, your short guidance about self signed certificate guidance will help to other SSL users.
