In onvif i come across the term KeyId/CertId/CertPathId and PassPhraseId what are these? How these are all created ?
回答1:
They are data types defined for the ONVIF Security Service.
As you can see in advancedsecurity.wsdl, they are all defined as xs:NCName with length 64.
Non Colonized Names are strings that stat with a letter or _ and that cannot have colons.
In ONVIF these values are just used to reference keys, certificates and so on, you can think about them as regular tokens.
