// This tests behaviour of authorization value handling. Some things to note
// from the reference TPM implementation:
// - Authorization values for objects are stored padded with trailing zeroes to
//   the size of the object's name algorithm.
// - Authorization values for hierarchies and NV indices are stored with trailing
//   zeroes removed.
// - EntityGetAuthValue removes trailing zeroes from an entity's authorization
//   value, prior to its use in the front end code when comparing comparing it
//   against a password session or using it to compute a HMAC key for a HMAC
//   session, or in the TPM2_StartAuthSession when computing the session key.
