How Do I Issue a Certificate for a Web Server?


Angela Bailey

When it comes to securing your website, one of the essential steps is issuing a certificate for your web server. A certificate ensures that the communication between your web server and the user’s browser is encrypted and secure. In this tutorial, we will explore how to issue a certificate for a web server.

What is a Certificate?

A certificate, also known as an SSL/TLS certificate, is a digital document that verifies the authenticity of a website and enables secure communication. It contains information such as the website’s domain name, organization details, and a public key.

Types of Certificates

There are different types of certificates available depending on your requirements:

  • Self-Signed Certificates: These certificates are generated by the web server itself. They are free but not trusted by default in web browsers.
  • Domain Validated (DV) Certificates: These certificates verify only the domain ownership.

    They are affordable and suitable for small websites or blogs.

  • Organization Validated (OV) Certificates: These certificates verify both domain ownership and organization details. They provide higher trust compared to DV certificates.
  • Extended Validation (EV) Certificates: These certificates offer the highest level of trust as they undergo thorough validation processes. The browser’s address bar turns green when using EV certificates.

The Certificate Issuance Process

The process of issuing a certificate involves several steps:

Step 1: Generate a Certificate Signing Request (CSR)

In order to obtain a certificate, you need to generate a Certificate Signing Request (CSR). This request contains information about your website and the public key. Most web servers provide tools or plugins to generate CSRs.

Step 2: Choose a Certificate Authority (CA)

A Certificate Authority is a trusted third-party organization that issues certificates. There are many CAs available, including Let’s Encrypt, Sectigo, and Digicert. Choose a CA based on your needs and budget.

Step 3: Submit the CSR

Once you have generated the CSR, submit it to the chosen CA for verification. The CA will validate the information provided in the CSR and ensure that you are the legitimate owner of the domain.

Step 4: Complete the Verification Process

The verification process may vary depending on the type of certificate you choose. It can involve email verification, phone calls, or manual document submission. Follow the instructions provided by your chosen CA to complete this process.

Step 5: Receive and Install the Certificate

After successfully completing the verification process, you will receive the certificate files from the CA. These files typically include a certificate file and an intermediate certificate file. Install these files on your web server as per your server’s instructions.

Renewing and Managing Certificates

Certificates have an expiration date, usually ranging from 1 to 2 years. It’s crucial to renew them before they expire to avoid any security warnings on your website. Most CAs offer management portals where you can easily renew and manage your certificates.

In Conclusion

Issuing a certificate for your web server is an important step in securing your website and ensuring encrypted communication with your users. By following these steps, you can obtain a trusted certificate for your web server and enhance user trust in your website’s security.
