Post-Quantum Crypto Migration in Rust: Bend for Persistence, Break for Ephemeral
The Anyhide project migrated to post-quantum hybrid encryption using ML-KEM-768, addressing the harvest-now-decrypt-later threat. For persistent codes, backward compatibility required a bend strategy with a wire format prefix. For ephemeral chat, a break strategy allowed a clean switch without legacy support.
