I think we can translate above struct into "the signal returns an
array of dict entries that key is type String and value is type
Variant". The Variant is used as container to hold any arbitrary
types.

If you try dbus-monitor it would report the signal "Certification" like this

    array [
        dict entry(
            string "depth"
            variant           uint32 1
        )
        dict entry(
            string "subject"
            variant           string "xyzxyz"
        )
        dict entry(
            string "cert_hash"
            variant           string "123456ABCDE"
        )
        dict entry(
            variant           array of bytes [
                  00 11 22 33 44
               ]
        )
    ]

Hope this answers the question and thank you so much for applying the patch. :)
