YACL (Yet Another Common crypto Library)

CircleCI OpenSSF Scorecard

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.

Supported platforms:

Linux x86_64 Linux aarch64 macOS x86_64 macOS Apple Silicon Windows x86_64 Windows WSL2 x86_64
yes yes yes1 yes no yes1
  1. Yacl has not been thoroughly tested on these platforms.

Repo Layout

  • base: some basic types and utils in yacl.
  • crypto: crypto algorithms without link.
  • kernel: crypto kernel that includes link with multi-thread support, i.e. OT, DPF.
  • io: a simple streaming-based io library.
  • link: a simple rpc-based MPI framework, providing the SPMD parallel programming capability.
