Upload Existing Root CA Certificate
If you have manually generated Root CA certificate on another machine or just have your self-signed Root CA pem file already, it is possible to upload it into the application. To do it open Admin UI / Squid Proxy / HTTPS (SSL) / Trusted Root Certification Authority . Click on the Upload New Certificate button, browse to your existing PEM file and click Upload Certificate button.
Your PEM file must contain both the private key and self-signed Root CA certificate. The file usually has the
-----BEGIN PRIVATE KEY----- and
-----BEGIN CERTIFICATE----- sections. The application does some internal checks of this file and will refuse to upload the file with incorrect contents.
