I have to create a certificate in Gateway via RESTMAN API. I created a PEM certificate on gateway server on LINUX machine. Now i opened the file and took the values between BEGIN CERTIFICATE and END CERTIFICATE.
By using the encode value of PEM file, i have successfully created the certificate in my gateway via RESTMAN API. My only query is : Do we need CA authority to sign the certificate or this default way is fine and secure enough. As i read online somewhere they created as it is , somewhere they use CA Authority and somewhere they created their own CA. Please guide me.
