                 ComPoint caComPoint) throws CertificateException, RuntimeException

 public void run()

Overrides:

run in class Thread

 public void sendTrustedPK(ComPoint comPoint) throws CertificateException

Send trusted public key to myClient. The trusted public key is the public key of the CA which is not certified. This key is simply sent to the client with no protection at all. This is a reply to a call of getTrustedPK at the client side.

Parameters:

myClient: - The client, that sent a getTrustedPK request and therefore shall get my trusted public key as requested.

Throws: CertificateException

if communication fails.

getTrustedPK

 public synchronized void sendTemplate(ComPoint comPoint) throws CertificateException

Send Template to myClient. This method is synchronised in order to avoid two different templates getting the same serial number. The client request a Template using sendTemplateRequest.

Parameters:

myClient: - The client, that sent a getTemplateRequest and therefore shall get a template as requested

Throws: CertificateException

if a send during this phase fails.

See Also:

sendTemplateRequest

 public synchronized Template getFilledTemplate(ComPoint comPoint) throws CertificateException

Get filled Template from client. This method also verifies signature on template against the public key to be registered (to crosscheck, whether the user indeed has access to the secret key which is the counterpart to the public key in the Template). This metod also computes a designated name for the client based on the information in the template (done by module). This designated name is sent to the client. The client sends the filled out template using sendFilledTemplate.

Parameters:

myClient: - Client who filled out Template.

Returns:

the filled out template if the verification and all communication succeeded. Null otherwise.

computeDN, sendFilledTemplate

 public synchronized void sendIssuedCertificate(ComPoint comPoint) throws CertificateException

Send issued Certificate to client. A user in the process of being registered can request a certificate using issueCertificateRequest. This service first verifies that the client has been registered. If not an error is sent to the client. If the user has been registered this service tries to issue a certificate. Whether this succeeds or not depends on the preferences set by the CA.

Parameters:

myClient: - Client who sent request to issue Certificate

Throws: CertificateException

if send fails.

getCertificateRequest

 public static void sendError(ComPoint comPoint,
                              String message) throws CertificateException

Send error: Send an error to the opposite side. This function is used to send an error, by first sending an ERROR code and then an error message.

Parameters:

comPoint: - comPoint to the other part

message: - Error Message to be sent

Throws: CertificateException

if the error couldn't be sent

 public void installRegistration(Registration reg) throws CertificateException

Store registration in Archive under special access name. This service has to be called in order to be able to retrieve the Registration later. The client can use this as well in order to store the registration locally.

Parameters:

reg: - the Registration that shall be installed.

Throws: CertificateException

if the Archive can't process the request.

 public static void storeCertificate(Certificate cert) throws CertificateException

Store certificate in Archive. Can also be used by client.

Parameters:

cert: - Certificate to be stored.

Throws: CertificateException

if store fails.

 public static Vector getLocalCertificates(Certificate partialCert)

getLocalCertificates retrieves a selection of local certificates (from the local archive). A partial Certificate, containing null or 0 for unidentified fields and correct values for the other fields is used as search criteria.

Parameters:

partialCert - is the Certificate containing search criteria.

Returns:

s a Vector of certificates from the archive matching the search criteria.

 public void sendCertificate(ComPoint comPoint) throws CertificateException

sendCertificate is a advanced version of sendIssuedCertificate. It is not maintained for the moment. It tries to send a list of certificates after receiving a request from myClient. In order to do so, the client has to send a partial Certificate, containing null or 0 for unidentified fields and correct values for the other fields.

Parameters:

Client - myClient is the client who sent a getCertificatesRequest.

Throws: CertificateException

if the retrieved certifiactes couldn't be sent to myClient.
