Necessary Information for the CSR
The CSR requires specific information to identify your organization and the purpose of the certificate. These details are crucial for the Certificate Authority (CA) to verify your identity. Common fields include:
- Common Name (CN): This is the most important field. It represents the hostname or domain name for which the certificate will be used. For example, if you are securing example.com, the CN should be example.com. Ensure the CN accurately reflects the domain you intend to secure.
- Organization (O): This field specifies the name of your organization. It’s crucial to use the exact name as registered with the CA.
- Organizational Unit (OU): This field details a specific division or department within your organization. For instance, “Web Servers” or “IT Department”.
- Location (L): Enter the city or locality where your organization is located.
- State/Province (ST): Enter the state or province where your organization is located.
- Country Name (C): Use the two-letter country code, such as “US” for the United States.
Generating the CSR using the pfSense Web Interface
Once you’ve gathered the required information, proceed to the pfSense web interface. Follow these steps:
- Navigate to System > Certificates.
- Click on “Create Certificate Signing Request”.
- Enter the required information in the provided fields. Pay close attention to the accuracy of the data, especially the Common Name (CN).
- Review all entries for correctness before proceeding.
- Click “Generate”.
