cryptographic protocol
Let an agent explain cryptographic protocols and their goals, relay major protocols and standards from IETF and academic sources, describe analysis and common weaknesses in general terms, and distinguish protocols from primitives and from applications.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

What it is Filled
A protocol that uses cryptographic primitives to achieve security goals such as confidentiality, integrity, authentication and non-repudiation between parties over a network, including key exchange protocols such as Diffie-Hellman and its post-quantum extensions, password-authenticated key agreement, authentication and secure channel protocols such as TLS with its cipher suites, and protocols for special tasks such as mental poker, secure multiparty computation and trustless systems such as blockchains; protocols are analysed formally and standardised by bodies such as the IETF.
Why it exists Filled
Let an agent explain cryptographic protocols and their goals, relay major protocols and standards from IETF and academic sources, describe analysis and common weaknesses in general terms, and distinguish protocols from primitives and from applications.

Open questions
- Should key exchange protocol and TLS be separate primary entries?
- How should RFCs and academic references be linked?
- The registry entry has merged aliases naming specific protocols and concepts; should they be split off?
- Which entry fits the specific protocol?
- Which entry fits Transport Layer Security?
- What deployment practices such as cipher suite selection and forward secrecy do standards recommend?
