To generate a CSR, you will need to create a key pair for your server. These two items are a digital certificate key pair and cannot be separated. If you lose your public/private key file or your password and generate a new one, your SSL Certificate will no longer match. You will have to request a new SSL Certificate and may be charged.
The CSR needs to contain the following attributes:
- Country Name (C): Use the two-letter code without punctuation for country
- State or Province (S): Spell out the state completely; do not abbreviate the state or province name
- Locality or City (L): The Locality field is the city or town name
- Organization (O): Your company or department
- Organizational Unit (OU): This field is the name of the department or organization unit making the request.
- Common Name (CN): The Common Name is the Host Name or Domain Name. Example "www.domain.com" or "domain.com".
Note: Comodo certificates can only be used on Web servers using the Common Name specified during enrollment. For example, a certificate for the domain "domain.com" will receive a warning if accessing a site named "www.domain.com" or "secure.domain.com", because "www.domain.com" and "secure.domain.com" are different from "domain.com". Comodo recommends that you contact Nortel for additional information.
