 Yacl is a C++ library that contains common cryptgraphy, network and io modules which other SecretFlow code depends on. The crypto modules in Yacl implement many state-of-art secure computation protocols, including primitives like OT, VOLE, TPRE, and tools like PRG, RO. Check the full list of Yacl's supported algorithms in [ALGORITHMS.md](ALGORITHMS.md).
