Detailed Description

This class incapsulates the operating environment of the TLS v1 (http://www.ietf.org/rfc/rfc2246.txt) Record Protocol and provides relating encryption/decryption functionality.

The work functionality is based on the security parameters negotiated during the handshake.

Constructor & Destructor Documentation

ConnectionStateTLS

(

SSLSessionImpl

session

)

[protected]

Creates the instance of TLS v1 Connection State.

All of the security parameters are provided by session object.

Parameters:

session,:

the sessin object which incapsulates all of the security parameters established by handshake protocol. The key calculation for the state is done according to the TLS v 1.0 Protocol specification. (http://www.ietf.org/rfc/rfc2246.txt)
