This is a great explanation but when using the library for Node.js or even your PHP implementation, the method to loadRootCAs() is commented as implementation may vary. I am a fairly new junior developer and I have never dealt with certificates or something even remotely similar. Could you point me in the right direction on how do I load certificates and what kind of implementations are we talking about? From what I understand so far is to read the certificate file and get the buffer from it?
