SSL : ofxHTTP vs. ofURLFileLoader


I’m digging into https request both with ofxHTTP and ofURLFileLoader, and there a thing i don’t understand : why with ofURLFileLoader I don’t need a SSL certificate for requesting on an https url and i need one if I use ofxHTTP ? it seems related to Poco::Net::Context creation, with the parameter Context::VERIFY_NONE or the path to the SSL ?
So with ofURLFileLoader the connection is not really secure ?
For ofxHTTP do i need the three .pem files in /bin/data/ssl (cacert, certificate and privateKey) ? or just one certificate is OK ?
There is not much documentation about this, this is why I have all this questions :slightly_smiling:
Thanks for your help !!
