.klickd: An Open Encrypted File Format for Portable AI User Context

.klickd is an open, locally-encrypted file format for portable AI user context. It serialises user preferences, competency state, domain rules, and conversational continuity into a structured JSON document, encrypted client-side using AES-256-GCM (PBKDF2, 600,000 iterations). No data transits any server. The file is the context.v1 targets education (EQF/ESCO/DigComp 3.0/CEFR alignment). v2 generalises to all domains (work, health, legal, creative, research) while maintaining full backward compatibility.The format is CC0 (public domain).

Abstract

.klickd is an open, locally-encrypted file format for portable AI user context. It serialises user preferences, competency state, domain rules, and conversational continuity into a structured JSON document, encrypted client-side using AES-256-GCM (PBKDF2, 600,000 iterations). No data transits any server. The file is the context.v1 targets education (EQF/ESCO/DigComp 3.0/CEFR alignment). v2 generalises to all domains (work, health, legal, creative, research) while maintaining full backward compatibility.The format is CC0 (public domain). Reference implementation and full specification: https://github.com/Davincc77/klickdskill
