qkd-stub wiki

Reference material for qkd-stub. Setup and quickstart are in the README.

• Ubuntu prerequisites: packages, rustup, container check
• Standalone provisioning: executable-only setup, CSR workflow, saved configuration, and two-endpoint demo
• Dashboard: qkd-stub-gui, a desktop window showing configuration, checks, and live client requests
• Deployment notes: separate machines, startup configuration
• Key ID and key derivation: encrypted UUIDv4 IDs, AES and HKDF formulas, checksum and collision limits
• Computational security: PSK-based secrecy without QKD, assumptions, conditional proof sketch and limits
• Forward-secrecy discussion: possible epoch ratchets, clock/counter tradeoffs, erasure and compromise recovery (not implemented)
• SAE authorization details: pair rules, certificate selector matching
• API details: status fields, errors, limits
• Development and testing: test commands and what they cover

These pages describe the behavior of the code on main. Update them with any change to the derivation, UUID layout or authorization rules.
