Implementing a Library for Pairing-based Transform Cryptography

Co-presented with IronCore Labs CTO Bob Wall. Walks through the practical challenges of building IronCore's open-source proxy re-encryption (transform cryptography) libraries - the pairing-based scheme behind recrypt / recrypt-rs - including the applied-cryptography pitfalls of implementing bilinear pairings in a production library.
