How Our CSR Generator Is More Secure
Most free CSR generation tools are server-based, which means that your private key is generated on the tool’s remote server (a server that’s not controlled by you) then sent via the internet to your browser. This leaves a serious security vulnerability—you don’t know what’s being done with your private key after it’s generated on the server.
That’s why we built our tool so everything happens inside your browser, where you have full control and visibility. Our CSR Generation Tool is a client-side app so the private key is generated and displayed inside your browser. Your private key stays private…it’s never even seen by our server.

"Very fast delivery. Installation was easy with no problems. If you are installing a wildcard SSL certificate on cPanel, you need to specify the actual domain name, don't try to install it on *.domain.com , you have to install it on each subdomain such as admin.domain.com, shop.domain.com,..etc. Use the same certificate for each subdomain you install. Good luck!"
