Description copied from interface: KeyIntegrityChecker

Checks the integrity of a KerberosKey to decrypt-decode and compare an encrypted encoded generalized timestamp representing the preauth data.

Specified by:

checkKeyIntegrity in interface KeyIntegrityChecker

Parameters:

encryptedData - the generalized timestamp encrypted with client hotp generated KerberosKey

kerberosKey - the KerberosKey generated from server side hotp value

Returns:

true if the key can decrypt-decode and make sense out of the timestamp verifying that it is in skew, false otherwise
