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 and a replacement has to be made.
Generate a Certificate Request
NOTE: A key length of 1024 bit is the default, but Geotrust recommends the use of a 2048 bit key. If the request is intended for an Extended Validation certificate or a certificate with a validity period beyond December 31, 2013, the 2048 bit key length will need to be selected.
Create a new certificate request using the Configuration utility.
To connect to the Configuration Utility: in a browser, enter the administrative IP address of the BIG-IP device:
1. A Security Alert dialog box appears, click Yes
2. The authentication dialog box appears
3. Enter user name and password
4. Click OK
5. The Welcome screen opens.
6. In the navigation pane, click Proxies > Create SSL Certificate Request tab
7. In the Key Information section, select a key length and key file name
8. In the Certificate Information section, enter the following information:
Country Name (C): Use the two-letter code without punctuation for country, for example: US or CA.
State or Province (S): Spell out the state completely; do not abbreviate the state or province name, for example: California
Locality or City (L): The Locality field is the city or town name, for example: Berkeley.
Organization (O): If your company or department has an &, @, or any other symbol using the shift key in its name, you must spell out the symbol or omit it to enroll. Example: XYZ Corporation
Organizational Unit (OU): This field is optional; but can be used to help identify certificates registered to an organization. The Organizational Unit (OU) field is the name of the department or organization unit making the request.
Common Name (CN): The Common Name is the Host + Domain Name. It looks like “www.company.com” or “company.com”. Geotrust 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”.
Please do not enter your email address, challenge password or an optional company name when generating the CSR.
9. Click Generate Certificate Request
10. In the SSL Certificate Request screen, start the process of obtaining a certificate.
