YubiKeyCapabilities Enum

Namespace: Yubico.YubiKey Assembly: Yubico.YubiKey.dll

A set of flags that describe the capabilities that are currently enabled on a YubiKey.

C#

[Flags]
public enum YubiKeyCapabilities

Remarks

This enumeration can be easily confused with the YubiKeyApplication enumeration. While these two enumerations share many values, they serve different purposes. For one - the YubiKeyApplication enumeration cannot be treated as flags. This enumeration represents the applications and interfaces exposed and enabled by a YubiKey. It includes things like "CCID" which is an interface, not an application. OTP and FIDO U2F, in the context of older generation keys like the YubiKey 4 Series and the YubiKey NEO, are also treated these as interfaces. This is in contrast to the YubiKey 5 Series which takes an application-based approach to capabilities.
