IIS: How to Create a Certificate Request

KB ID 0000840 


If you would like to obtain a digital certificate either from your own CA, or from a public certificate vendor, you need to submit a certificate signing request (csr) first.


Note: I’m making the assumption you have already installed the Web Server (IIS) role on your server.

1. Windows Key+R > iis.msc {Enter} > Select the servername > Server Certificates.

2. Create Certificate Request > Fill in the details > Next.

Note: The Common name will be the name on the certificate, e.g. If this certificate is going to secure https://sitea.domain.com then the common name would be sitea.domain.com.

3. Note: For IIS generally 1024 bits will be fine, but I suggest you use a 2048 bit length > Next.
