Angela Bailey

In order to request a web server certificate, there are several key elements that should be included. These elements are necessary to ensure the security and authenticity of your website. Let’s delve into the details:

Common Name (CN)

The Common Name (CN) is a crucial piece of information that identifies the domain name for which you are requesting the certificate. It should match the domain name exactly, including any subdomains.

Organization (O)

The Organization (O) field represents the legal entity that owns or controls the domain. It could be a company, an organization, or an individual.

Organizational Unit (OU)

The Organizational Unit (OU) field further categorizes the organization specified in the O field. It can represent different departments or divisions within a company.


The Location field includes information about where your organization is physically located. It typically consists of the city or town, state or province, and country.

Email Address

Providing an email address is essential for communication regarding your certificate request. Make sure to provide a valid email address that you have access to.

Key Size

The Key Size refers to the length of the cryptographic key used for encryption and decryption purposes. The recommended key size for web server certificates is 2048 bits.

Certificate Signing Request (CSR)

To generate a web server certificate request, you’ll need to create a Certificate Signing Request (CSR). This file contains all the necessary information mentioned above and is used by a Certificate Authority (CA) to issue your certificate.

  • Common Name: The domain name for which the certificate is requested.
  • Organization: The legal entity that owns or controls the domain.
  • Organizational Unit: The specific department or division within the organization.
  • Location: The physical location of the organization.
  • Email Address: A valid email address for communication.
  • Key Size: The length of the cryptographic key used for encryption and decryption.

Once you have gathered all the required information, you can create a CSR using various methods depending on your web server software. Consult your web server’s documentation for specific instructions on generating a CSR.

In conclusion,

A web server certificate request should include the Common Name, Organization, Organizational Unit, Location, Email Address, and Key Size. These elements are essential to ensure accurate identification and secure communication between your website and its visitors. By providing this information accurately, you’ll be on your way to obtaining a trusted web server certificate.
