Supporting routines overview

There are some classes in the SDK that are not directly related to the YubiKey. Each of these classes performs some sort of support operation.

For example, the TLV classes (see TLV support) are used to build and parse "tag-length-value" constructions. These classes do not call on the YubiKey to do any work, but rather help format and parse data as required by the YubiKey.

Many developers will never need to use these support classes. However, it is possible that an application will need to perform some of the operations these classes do. It will likely be easier to take advantage of the SDK's implementations, rather than write them all over again.
