How to generate CSR?

If your web hosting control panel has an option to generate CSR, we highly recommend using that tool.

Otherwise, please click here and generate your CSR in seconds. All you need to do is type your domain names (separated by the comma, for multiple domains) in that page. Then in seconds, we'll generate your private key and CSR; and you'll get two buttons to

1. Download the private key and

2. Copy the CSR

Paste the CSR in the form of this page. Isn't that very simple? Cheers!


The private key and CSR are generated using Webcrypto API in your browser. The private key doesn't transmit over the internet, and our server never sees it.

As an added security, you may disconnect the internet connection during CSR generation. You may also download the app from GitHub and run locally using a browser.
