YACL (Yet Another Crypto Library)

A C++ library that contains cryptgraphy, network and io modules which other SecretFlow code depends on.

Repo layout:

• base: some basic types and utils in yacl.
• crypto: a crypto library desigend for secure computation and so on.
  • base: basic/standarized crypto, i.e. AES, DRBG, hashing.
  • primitives: crypto primitives, i.e. OT, DPF.
  • tools: theoretical crypto tools, i.e. Random Oracle (RO), PRG.
  • utils: easy-to-use crypto utilities.
• io: a simple streaming-based io library.
• link: a simple rpc-based MPI framework, providing the SPMD parallel programming capability.
