Visual
The protocol pieces are IETF documents. The governance body on the page this lab opened is the STI-GA.
Worked example
Find the header The Identity value is a placeholder. Do not treat it as a signature.
- Open the dissector.
- Find Identity.
- Say which RFC defines the header.
Fault
A test tool shows Identity: <study-token-not-a-real-passport> and the display name matches. The ticket says SHAKEN passed.
RFC 8225 describes a cryptographic token. This lab's string is not one.
