Hybrid PQC E-Mail Communication: Easing Migration Pain
summary
Prototype implements a Certificate Authority, Certificate Management System and an extended open‑source e‑mail client with a Microsoft Outlook integration module, and successfully exchanges signed and encrypted messages using Certificate Authority, Certificate Management System plus hybrid certificates. Implementation uses a GnuPG/Outlook plugin and Kleopatra for key management and modifies an existing CA to issue Composite and ICA hybrid keys with Bouncy Castle for crypto; hybrid e‑mail works end‑to‑end but automatic encryption key distribution, HSM support and proof‑of‑possession remain unresolved.
