What is a CSR?

A Certificate Signing Request (CSR) is a required file when applying for an SSL/TLS certificate. It contains your organization details and public key.

How to Generate Your CSR in 3 Easy Steps:

  1. Fill in the Form
    • Enter your details (like domain name, company info) using standard text.
    • Click the "Generate CSR" button.
  2. Download Your Files
    • Your CSR (.txt file) will download automatically.
    • Important: The file includes both your CSR and Private Key – keep it secure!
  3. Use Your CSR
    • Submit the CSR when ordering your SSL certificate.
    • Save the Private Key – you'll need it to install the certificate later.
