aperçu
Server-side of the Universal 2nd Factor (U2F) protocol
historique
libu2f-server is Yubico's C implementation of the server-side Universal 2nd Factor protocol, providing APIs and a small command-line tool for U2F registration and authentication flows.
Yubico built libu2f-server for relying-party applications that needed to generate U2F registration and authentication JSON challenges and verify the cryptographic responses from U2F devices. Its README pairs it with libu2f-host, the host-side library and tool for talking to U2F authenticators.
The project followed semantic versioning and shipped a u2f-server debugging/testing utility. Its README also documented an important attestation-certificate limitation: the library did not validate the full X.509 attestation chain at registration time.
The library belongs to the first wave of open-source U2F building blocks around the FIDO U2F 1.0 and 1.2 specifications. It was useful when web services and system integrators were adding hardware second-factor support before WebAuthn and FIDO2 became the dominant developer-facing APIs.
Yubico later moved the U2F libraries into maintenance and end-of-life status. Yubico's EOL page lists libu2f-server with a March 16, 2020 announcement date, March 16, 2021 end-of-life date, and libfido2 as the recommended alternative.
Applications used the library to create registration and authentication challenges and verify responses. Operators and developers could use the u2f-server command with key-handle and public-key files to test registration and authentication flows together with libu2f-host.
libu2f-server is a neat package-history marker for the transition from U2F-specific libraries to FIDO2/WebAuthn stacks. It also shows the older split between host-side and server-side U2F packages that many distributions carried before libfido2 consolidated U2F and FIDO2 support.
