We present a multi-language, cross-platform, open-source library forasymmetric private set intersection (PSI) and PSI-Cardinality . We further apply our library to two use cases: (i) aprivacy-preserving contact tracing protocol that is compatible with existing approaches, but improves their privacy guarantees . Currently, our library supports C++, C, Go, WebAssembly,JavaScript, Python, and Rust, and runs on both traditional hardware (x86) and browser targets .
