Description:
Perl module to register and authenticate U2F compatible devices
Universal 2nd Factor (U2F) is an open authentication standard that strengthens and simplifies two-factor authentication using specialized USB or NFC devices based on similar security technology found in smart cards. . Crypt::U2F::Server module implements the server side of U2F authentication through Yubico's C library. . Prefer to use Crypt::U2F::Server::Simple since Crypt::U2F::Server is a very low level wrapper around the original C library.
