Yubico Universal 2nd Factor (U2F) Server C Library
This is a C library that implements the server-side of the U2F protocol.
More precisely, it provides an API for generating the JSON blobs required
by U2F devices to perform the U2F Registration and U2F Authentication
operations, and functionality for verifying the cryptographic operations.
There is no official package available for openSUSE Leap 15.4
