Practitioner informative
A ten-page white paper explaining how KERI addresses two quantum threats: a surprise quantum attack on signing keys, met by pre-rotation behind hash digests, and harvest-now-decrypt-later attacks on confidentiality, left to the application layer through out-of-band key exchange or hybrid key encapsulation. It places this within NIST's post-quantum timeline and argues for crypto-agility, for decision makers and practitioners.
