ClusterCS is a cloud-based control panel that simplifies server and domain management for Linux-based web servers. Founded in
2008, it provides a centralized interface to manage servers, domains, and web applications, while offering features like smart
caching, one-click SSL, automatic backups, and high availability clustering. ClusterCS aims to solve the challenges of server
administration, infrastructure scaling, and website performance optimization through its automation-oriented software and

Step 1. Generating a CSR and Private Key

CSR:- The Key to Client-Server
A CSR serves as the key to establishing trust between clients and servers in the SSL ecosystem. Generated by the client, it
encapsulates essential information such as the server's public key and organizational details, which are verified by Certificate
Authorities. SEO benefits from optimized CSR management, as it fosters secure connections, elevating website credibility and
search engine rankings through robust encryption protocols and heightened 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. Here is a bit of information about SSL Certificates to help choose the best for you and your website.

DV, OV, EV – what do all these letters mean, and why are they important for your website? In this guide, we'll break down the alphabet soup of
SSL certificates, explaining the differences between Domain Validation (DV), Organization Validation (OV), and Extended Validation (EV) certificates.
Get ready to navigate the world of online security like a pro!

DV (Domain Validated) SSL certificates verify only domain ownership, making them the quickest and most affordable option suitable for basic
encryption needs. OV (Organization Validated) certificates validate domain ownership and the organization's identity, offering increased credibility.
EV (Extended Validation) certificates provide the highest level of assurance, undergoing a rigorous validation process that includes verifying legal
entity details, resulting in a distinct green address bar in web browsers, enhancing trust and security for visitors.

SSLTrust has established partnerships with all the leading SSL Certificate Authorities and here are some of our best sellers you can choose from:-

Comodo Positive SSL - Perfect for a small business or a portfolio to secure a single website

Sectigo Business SSL - Affordable Business Grade Security for organizations

Verokey Secure Business Pro Multi Domain SSL - Tailored Enterprise Security Solution for multiple company domains

In conclusion, choosing the right SSL certificate type depends on the level of validation and trust you want to establish for your website. Whether you opt for a DV, OV, or EV certificate, implementing SSL encryption is crucial for protecting sensitive data and providing a secure browsing experience for your users. If you're still unsure of what certificate to choose for your business, please contact our Sales Team and they will be glad to help you out.

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
