so you are directly setting the key used for authentication.

To set the keys for a user, you can use the following constructor (the
passed passphrases are in fact used as keys):

  public UsmUser(OctetString securityName,
                 OID authenticationProtocol,
                 OctetString authenticationPassphrase,
                 OID privacyProtocol,
                 OctetString privacyPassphrase,
                 OctetString localizationEngineID)

Regards,
  Jochen
