Migrating and benchmarking a banking application
summary
A Java bank personal-communication channel is migrated to post-quantum primitives by replacing all key-exchange and signature operations with PQC counterparts, integrating Bouncy Castle + BC-PQC as the crypto provider and refactoring hardcoded ciphers into interfaces for crypto agility. The proof-of-concept touches about 64 files changed, exposes interoperability edits for DB key formats, and uncovers no fatal functional breakages; the baseline migration completes in 3–4 weeks by 2–3 developers. Benchmarks are pending and hybrid-mode behavior remains untested.
