A CSR (Certificate Signing Request) is a block of encoded text that contains information about your website and organization. It is required when applying for an SSL certificate.

The CSR includes:

  3. Select key type and size
    Recommended: RSA 4096 for better security.
  4. Send me the CSR/KEY (Optional): recommanded to have a copy of your private key.
  5. Click Generate CSR
  6. Save both files:
