Knowing the Certificate Signing Request process makes installing and renewing your SSL certificate a simple task. In securing your website with an SSL certificate, a CSR plays a pivotal role, as it establishes a connection between your server’s public key and the CA. This connection ensures that the SSL certificate issued is valid for your specific domain and organization, enhancing the security and authenticity of your website.

The Certificate Signing Request Process
When generating a CSR, the server administrators will use their server software to create a CSR. During this process, the software will prompt for all the relevant details that need to be submitted by you.
Once the CSR is generated, it is sent to the chosen Certificate Authority, where the CA uses the CSR to validate the website owner, organization, and domain name.
Bear in mind that providing accurate and complete information in the CSR contributes to the integrity and trustworthiness of your online presence as well as helping ensure the validation process goes smoothly.
Once the information is validated, the CA issues the SSL Certificate that matches the information given in the CSR. The SSL certificate can then be installed on the corresponding server.
What is a CSR?
The Certificate Signing Request (CSR) is the file that contains information about your organization and the domain name you are using for an SSL/TLS certificate.

The CSR is generated on the same server where you plan to install the certificate. It contains the public key that will be included in your SSL certificate and is signed with the corresponding private key.
The CSR contains the fully qualified domain name or common name, organization details, location and public key that the Certificate Authority (CA) will use to generate an SSL certificate. Once the relevant CA verifies the information in the CSR, they will issue an SSL/TLS certificate that you can install on your server.
Why You Need a CSR
SSL certificates play a vital role in securing website and user data by ensuring it is not read or changed by unauthorized users or software. To obtain an SSL certificate, a CSR is required, as it establishes a connection between your server’s public key and the CA to generate it corresponding private key.
This ensures that the SSL certificate issued is valid for your specific domain name and organization, enhancing the security and authenticity of your website.

Additional Information
Public and Private Keys
Public and private keys are made up of a sequence of numbers and used for data encryption during transfer. Public keys can be made available to anyone and are used to encrypt data, while private keys are confidential and are used to decrypt data.
When data is transferred between a browser and web server, both keys are needed. The two keys are paired but are identical. This means information encrypted with a public key cannot be decrypted with the same public key. To decrypt the data, the corresponding private key is required.
Certificate Authority
A Certificate Authority (CA) is an independent organization that issues various digital certificates for websites. The main role of CAs is to authenticate a website’s domain and ownership, done via a CSR. After the CSR is generated, it is sent to a CA, who will verify that the information it contains is authentic and correct. It will then issue the private key for the applicant’s SSL certificate’s public key.
