Step 1. Generating a CSR and Private Key

CSR: A Key Component for SSL Certificate Issuance
A CSR (Certificate Signing Request) is a pivotal element in obtaining SSL certificates, containing
crucial data such as the server's public key and domain information. When a client seeks to secure their
website with SSL, they generate a CSR, which is then submitted to a Certificate Authority (CA) for
validation. Effective CSR utilization is paramount for SEO, as it facilitates the issuance of trusted
SSL certificates, enhancing website security and search engine rankings through encrypted connections
and improved user trust.

Navigate to SSLTrust's CSR Generator and generate your CSR and Private Key.

Note:- Save the generated Private Key and CSR on your device. This might come in handy if you want to re-do the configuration.

Step 2. Order and Configure the SSL Certificate

The following step in the installation process is to order and configure SSL Certificate. We recommend SSLTrust because of our exceptional Customer Service, Money Back guarantee and SSL Installation Service.

4: Fill in your contact information

Contact Info

If you have a technical contact managing the certificate for you, please enter their details.
They will also have permission to manage the Certificate and will be sent renewal reminders.

Technical Contact

To obtain a business SSL certificate, you will need to provide your business details, including your correct address, phone number, and legal entity name. The Certificate Authority will verify the accuracy of this information. If there are any mistakes, it may cause delays in the process.
Then, click on Next Step

5: The next step in this process is Domain Control Validation (DCV).
DCV, or Domain Control Validation, is a crucial step in SSL certificate issuance. It verifies that the entity requesting the certificate has control over the specific domain by utilizing methods like email verification, file uploads, or DNS changes. This process ensures the legitimacy of SSL certificates and enhances online security.

Domain Control Validation

Select the method that is easiest for you. Having an email address with the domain name will be the quickest.
You will be sent an email containing a link which when clicked upon should validate your domain name.
In HTTP/HTTPS File Validation Method, you can create a folder in the specified and directory, paste in the contents and your domain should be validated.


The final method to validate your domain name would be CNAME Validation. Basically you have to create a CNAME record in your DNS Settings to validate your domain name and then click on the Check DNS Record button to verify DNS changes.


After a few seconds or minutes depending on your DNS propagation speed, the CNAME record should be verified.

DNS Check DNSChecker

The configuration should be a success. Click on the button below to access the validation manager.

6: Your certificate should have now been issued if you completed all the above steps correctly.

Certificate Issue Success

If not, click on Domain Control Validation, and re-submit whatever method you chose for validation.
Upon completing domain validation using the chosen method, your SSL certificate will be issued. If you have ordered a Business SSL, you will need to wait for the Certificate Authority to verify your business address and phone number. If the validation process has not been completed or you have not received your certificate after a certain period of time, please reach out to the support team to check on the status of your certificate.

Step 3. Upload the SSL Certificate Files to your Server

Once your SSL certificate has been issued, you will receive an email with the certificate directly from the Certificate Authority. Alternatively, you can download the certificate from the SSLTrust Portal, which presents the certificate in a convenient, easy-to-use format.

Again, head over to the SSLTrust Dashboard and click on your certificate:-

  ssl_certificate_key <%/etc/certs/private.key%>;
