# CESR: Composable Event Streaming Representation

A 22-slide deck introducing CESR (Composable Event Streaming Representation), the dual text and binary encoding for cryptographic primitives and groups used across the KERI suite. It covers the three domains (raw, compact binary, text), code tables, tritet parsing, the master code table, stream parsing rules, and uses in archiving, legal signatures and audit trails, for implementers.

Labels: reading level Implementer; evidence informative (an author's paper, deck, tutorial or post explaining the suite).
