Steps to Generate CSR on RedHat Linux

Here is a detailed process for generating a CSR on RedHat Linux to use for a website while issuing the SSL Certificate:

  • Open the OpenSSL configuration file
  • You can find that file at /etc/ssl/openssl.cnf location.
  • Find the section titled “[req]”
  • Add the following line underneath it:
default_bits = 2048

This will set the key length for the CSR to 2048-bit

  • Run the following command to generate a private key that will be used to create the CSR.
openssl genrsa -des3 -out blog.key 2048
  • This will prompt you for a passphrase to encrypt the private key. Be sure to remember the passphrase.
  • Run the following command to create the CSR using the generated private key
openssl req -new -key blog.key -out blog.csr

To complete the CSR process, make sure to fill up all required details correctly.

  • Country Name (2-letter code)
  • State or Province Name
  • Locality Name
  • Organization Name
  • Organizational Unit Name
  • Common Name – This should be the fully qualified domain name of your blog
  • Email Address

The CSR file generated will be called websitename.csr; it contains the information to identify your website and needs to be submitted to a Certificate Authority (CA) to generate an SSL certificate.

Once you have the certificate from the CA, you can install SSL on the RedHat Linux server to encrypt your website’s traffic.
