Frequently asked questions
Where is the private key generated?
The private key is generated on the server using OpenSSL. It is returned to your browser but never stored on our servers. Save it securely - it cannot be recovered after leaving this page.
What do I do with the CSR?
Submit the CSR to a Certificate Authority (CA) like Let's Encrypt, DigiCert, or Comodo. They will issue a signed certificate.
Why does the private key have a warning?
Anyone with the private key can decrypt traffic intended for your certificate. Keep it secret and never share it.
