Details for CSR Generation, How to create acme certificate for pfsense box firewall
A properly crafted CSR is essential for the successful issuance of your certificate. Key details must be accurately specified for the CSR to be valid.
- Common Name (CN): This is the most crucial field, identifying the domain name or hostname for which the certificate will be used. For example, if the certificate is for `www.example.com`, the CN should be `www.example.com`. A correct CN ensures that the certificate is associated with the correct domain.
- Alternative Names (SANs): This field allows you to specify additional hostnames or domain names that the certificate should also cover. This is essential for websites with multiple subdomains or services hosted on different names.
- Organizational Details: The organization name, organizational unit name, and location are needed for proper certificate identification. Accurate information ensures that the certificate reflects your organization’s identity and legitimacy.
- Country Name (C): This is the two-letter country code, specifying the country where your organization is located.
OpenSSL CSR Generation on pfSense
Generating a CSR using OpenSSL on pfSense involves specific command-line arguments. A typical example for generating a CSR for `example.com` is shown below:
openssl req -new -newkey rsa:2048 -nodes -keyout example.key -out example.csr -subj “/C=US/ST=California/L=San Francisco/O=Acme Corp/OU=IT/CN=example.com”
This command generates a 2048-bit RSA key, creates a CSR file (`example.csr`), and a private key file (`example.key`). The `-subj` option specifies the subject details, crucial for accurate certificate identification.
