Display key check value

You can check that a key matches an expected key value, without revealing anything about the actual key value, by viewing its key check value (KCV).

The KCV is a standard technique for obtaining an identification fingerprint from a key. The mechanism used, compatible with AS 2805, is simply the first three hex digits obtained by encrypting binary zeros with the key. Please refer to Creating keys for details of KCV generation.

To display the KCV for a key

Select a key from the Objects on Selected Token list and select the View button on the toolbar.

Alternatively, select Options > View from the menu bar.
