Two standards are involved here: Webauthn is the protocol by which a website (a "Relying Party") communicates with your application. How these values and the authentication results are communicated with the Relying Party is an implementation detail for users of these crates.Ĭonceptually, working with Passkeys involves receiving requests for registration of new credentials, storing those credentials, and performing authentication with existing credentials. It is not within the scope of these libraries to manage the details of the interaction with the Relying Party. ![]() Much of the type naming in these libraries refer directly to the terms used in these standards and being familiar with their terminology will greatly aid your understanding of how to use these libraries.Įxamples in this documentation shows certain values being assumed to come from the website (Relying Party). In understanding how to use this library, developers should read the Webauthn Level 3 and CTAP2 standards. public-suffix - a library which efficiently determines the effictive Top-Level Domain of a given URL, based on the Mozilla Public Suffix List.passkey-types - type definitions, usable as types for the -client and -authenticator libraries.passkey-transports - a library, usable as transports, which implements the CTAP HID protocol.passkey-authenticator - a library, usable as authenticator, which implements the CTAP2 standard.passkey-client - a library, usable as client, which implements the Webauthn Level 3 standard for authentication to websites.The passkey-rs library is a collection of Rust libraries to enable developers to use Passkeys in Rust code through a comprehensive implementation of both the Webauthn Level 3 and CTAP2 standards. ![]()
