Release date: June 30th, 2022

Features:

  • AES-based PIV management keys. Newer versions of the YubiKey (firmware 5.4.2 and above) have the ability to use AES-based encryption for the management key. This is in addition to the existing Triple-DES based management keys. Read the updated PIN, PUK, and Management Key article for more information.
  • FIDO U2F. Applications using this SDK can now use the YubiKey's FIDO U2F application. This means that the SDK is now also enumerating the HID FIDO device, in addition to the HID keyboard and smart card devices exposed by the YubiKey. Use this feature if your application wants to handle U2F registration or authentication. Note that on Microsoft Windows, applications must run with elevated privileges in order to talk to FIDO devices. This is a requirement set in place by Microsoft. See FIDO U2F overview for more information.
  • SCP03. Secure Channel Protocol 03 (also referred to as SCP03) is a Global Platform specification that allows clients of smart cards to encrypt all traffic to and from the card. Since the YubiKey can act as a smart card, this means that it is now possible to encrypt all traffic for the OATH, PIV, and OpenPGP applications. In order for this to work, however, your YubiKey must be pre-configured for this feature. Read more about SCP03 here.
  • Debian, RHEL, and CentOS support. Our testing of Linux platforms has expanded to include the Debian, Red Hat Enterprise Linux (RHEL), and CentOS distributions. Please read running on Linux for more details.

Bug fixes:

  • High CPU usage when the SDK can't connect to the smart card subsystem.
  • Yubico.NativeShims DLL not found when using .NET Framework 4.x. Note that there is an additional issue with packages.config that is not able to be resolved. Developers are urged to upgrade to the newer method if at all possible. Manual installation of the Yubico.NativeShims library will be necessary if you are stuck on packages.config.
  • "Duplicate resource" error when compiling for UWP applications.
