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 then sent via the internet to your browser. This leaves a serious security vulnerability.

That’s why we built our tool so everything happens inside your browser. Your private key stays private…it’s never even seen by our server.
