All, For anyone interested, a new COSE message dissector and a new CBOR decoding API has been recently merged to the main branch of Wireshark [1]. For new dissectors of protocols which use CBOR as their encoding, this "wscbor" API gives a higher-level of abstraction (e.g. "text = wscbor_require_tstr(...)") and robustness to both tags and errors in structure and well-formedness. Hopefully this will be helpful to other dissectors, since there are quite a a few CBOR-based protocols in the works. Thanks, Brian S. [1] https://gitlab.com/wireshark/wireshark/-/issues/17384
