Sunscreen's compiler

Our goal is to make it easy for any engineer to write an FHE program. To accomplish this, we've been working to get the API just right (we're always excited to hear feedback from users!). A large part of this was choosing the right language for our compiler— we chose Rust. In addition to having a powerful and expressive type system, Rust is very well suited to cryptography. It's highly performant (like C/C++) and safe by design (unlike C/C++).

Our compiler relies on Microsoft's SEAL library. There are many different types of FHE schemes out there; we've chosen to use the BFV fully homomorphic encryption scheme—named for the authors (Brakerski-Fan-Vercauteren) who came up with the scheme.
