Interface CertificateListener

All Known Implementing Classes:

public interface CertificateListener

When a SSONETClientSocket connects to a SSONETServerSocket, Certificates are exchanged. When a certificate arrives, the listeners method checkCertificate is called to determine, whether the certificate is accepted or not. A CertificateListener implementation may return:

• VALID, if the certificate was tested and was found to be valid,
• INVALID, if the certificate was tested and was found to be invalid,
• NOT_TESTED, if the certificate was not tested.

There may be multiple CertificateListeners listening to one SSONETContext. A certificate is considered valid, if at least one CertificateListener returned VALID and none returned INVALID, otherwise it is considered to be invalid, ad the connection is rejected.

Field Summary

static int	INVALID Constant, which must be returned by a CertificateListener implementation, if the certificate was testet, and it was found to be invalid.
static int	NOT_TESTED Constant, which must be returned by a CertificateListener implementation, if certificate was not testet, and so no decition about the validity of the certificate was possible.
static int	VALID Constant, which must be returned by a CertificateListener implementation, if the certificate was testet, and it was found to be valid.
