// Interoperable Private Attribution (IPA) is a new web platform API for
// advertising attribution.
//
// It proposes two new user-agent APIs: `get_encrypted_match_key` and
// `get_helper_networks`.
//
// The match keys which leave the user agent are always encrypted towards a
// privacy preserving measurement system, i.e., a distributed multi-party
// computation (MPC) operated by helper parties who are only trusted to not
// collude.
//
// PrivateAttribution object exposes these APIs to the window and is responsible
// for accepting the parameters, calling browser functions and returning the
// results back to the api caller.
