public final class KeyUsage
extends Object
implements Comparable<KeyUsage>

From RFC 4120, "The Kerberos Network Authentication Service (V5)": 7.5.1. Key Usage Numbers The encryption and checksum specifications in [RFC3961] require as input a "key usage number", to alter the encryption key used in any specific message in order to make certain types of cryptographic attack more difficult. These are the key usage values assigned in [RFC 4120]:
