crypto-protocol-diagram

You can generate a sequence diagram from a cryptographic protocol specification by extracting message flow and cryptographic operations to produce a Mermaid sequenceDiagram with detailed annotations and an inline ASCII diagram.

Yes, you can convert ProVerif (.pv) or Tamarin (.spthy) formal models into rendered message sequences by systematically identifying parties, tracing sender/receiver message order, and emitting both Mermaid and ASCII sequence diagrams.

Cryptographic operations are annotated in Mermaid sequence diagrams by labeling key steps such as DH/ECDH, KDF/HKDF, signing/verifying, encryption/decryption, hashes, commits, and secret sharing directly within the message flow.

Yes, this protocol diagramming approach supports branching and abort paths by surfacing success versus failure flows using Mermaid alt blocks and highlighting missing or ambiguous specification details with warning markers.

The best way to visualize a crypto handshake from an RFC or pseudocode is to derive a sequence diagram by extracting parties, tracing message order, and labeling cryptographic transformations to output both Mermaid and ASCII diagrams.

When converting formal verification models to sequence diagrams, missing or ambiguous specification details are highlighted with warning markers rather than resolved, and output is strictly limited to Mermaid and ASCII formats.
