keripy — Python KERI Reference Implementation

Overview

keripy is the canonical Python implementation of KERI (Key Event Receipt Infrastructure), providing the complete protocol stack: CESR primitives, event creation/validation, key state management, LMDB persistence, identifier lifecycle (Habery/Hab), credential registries (VDR), and IPEX credential exchange. It uses HIO (Hierarchical Input/Output) for async orchestration via Doer subclasses.

keripy follows the KERI naming conventions: gerund modules (-ing), agent noun classes (-er), codex tables (-Dex), transform functions (-ify), and namedtuple results (-age).

Companion skills: For CESR encoding theory and code tables, see cesr. For KERI event model and validation rules, see spec. For ACDC credential structure and IPEX protocol, see acdc.
