How to Cause the SSL Handshake Failure
SSL (Secure Socket Layer) is the primary encryption-protocol algorithm used on the Internet to secure websites and prevent eavesdropping. SSL requires several parameters, such as time and date, from both the client and the server to establish an SSL session. Testing an SSL implementation to ensure that the server handles error conditions gracefully is extremely important to ensure the security of information exchanged during an SSL session. Change time and data parameters to cause an SSL handshake failure to test secure Web-server configuration.
