⚠️ Notice

This project is currently under active development and should not be used in production. Expect bugs and regular major breaking changes. Use at your own risk.

Protocol crates

These crates implement complete, high-level protocols. Each top-level crate is paired with an IO-free *-core crate containing the protocol logic; supporting crates (primitives, circuits, execution, VM, and tooling) are intentionally not listed here.

• ot (ot-core) - Oblivious transfer.
• garble (garble-core) - Garbled circuits.
• ole (ole-core) - Oblivious linear evaluation.
• zk (zk-core) - Zero-knowledge proofs.
• share-conversion (share-conversion-core) - Multiplicative-to-additive and additive-to-multiplicative share conversion.
• cointoss (cointoss-core) - Two-party coin toss.

Testing on WASM

Tests and benchmarks can run on wasm32-wasip1 and wasm32-wasip1-threads through wasm-harness. See WASM.md for setup, engines, commands, and limitations.
