YACL (Yet Another Common crypto Library)

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

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.

Prerequisites

• bazel: the recommended verion is described in .bazelversion file. We recommend to use the official bazelisk to manage bazel version.
• gcc >= 10.3
• cmake
• ninja/ninja-build
• Perl 5 with core modules (Required by OpenSSL)
