U2fBuffer Class

Namespace: Yubico.YubiKey.U2f Assembly: Yubico.YubiKey.dll

This is a base class for those classes that need to collect and encode data into a single buffer, either as data in a command or data to verify. This will hold the buffer along with the Application ID Hash and Client Data Hash. Subclasses can add more data to be placed into the buffer.

Remarks

Only the SDK will ever need to create subclasses, there is no reason for any other application to do so.
