Proof-of-Possession Key Semantics for CBOR Web Tokens (CWTs) spec with a few improvements

IETF logoA few local improvements have been made to the Proof-of-Possession Key Semantics for CBOR Web Tokens (CWTs) specification. Changes were:

  • Changed “typically” to “often” when describing ways of performing proof of possession.
  • Changed b64 to hex encoding in an example.
  • Changed to using the RFC 8174 boilerplate instead of the RFC 2119 boilerplate.

Thanks to Samuel Erdtman for sharing the editing.
