Modern, Functional Cryptography (Part 2)
summary
Workshop builds a working cryptographic library in Scala with typeclasses and runnable exercises, using tsec, SBT and IntelliJ, and shows actual code rather than theory. Concrete claims: AES CTR/GCM nonce reuse lets an attacker recover plaintext via XOR given a chosen plaintext oracle. The session walks through a hands‑on cryptographic library based on laws and typeclasses, offers a reproducible CTR nonce-reuse chosen-plaintext XOR exercise, and demonstrates how the examples run and fail when IVs or key management are wrong.
