4. Another new window will appear where it is necessary to enter Distinguished Name Properties (domain name and your contact details for the certificate request) . Every field should be filled only with alphanumeric characters and cannot be empty. The descriptions are explained below:

  1. Common name – fully qualified domain name you wish to secure with the SSL certificate, for example, domain.com or www.domain.com. For the wildcard certificate, put an asterisk in front of the domain name so that it looks like *.domain.com;
  2. Organization – full name of the officially registered company, or you can just put “NA”;
  3. Organization unit – specific department of the company provided above; can be specified as “NA” too;
  4. City/locality – full name of the city or town;
  5. State/province – full name of the state or province. If you do not have one, just put your city or town name;
  6. Country/region – two-letter country code from the drop-down.

5. Click “Next” and a new screen will appear. Select “Microsoft RSA SChannel Cryptographic Provider” as the cryptographic service provider. Starting from December 20, 2010, 1024-bit key length is considered insecure, so it is necessary to select 2048 bit length:

7. Click “Finish” to complete the generation. Now you can find the text file with the CSR code in the selected folder. You need to copy the whole contents along with the -----BEGIN NEW CERTIFICATE REQUEST----- and -----END NEW CERTIFICATE REQUEST----- lines and paste the code in the corresponding box during activation. Note: Before activating the certificate, you can check if the CSR code is generated correctly via this online tool .
