Constructor Detail

TlsClientProtocol

public TlsClientProtocol(java.io.InputStream input,
                 java.io.OutputStream output,
                 java.security.SecureRandom secureRandom)

Constructor for blocking mode.

Parameters:

input - The stream of data from the server

output - The stream of data to the server

secureRandom - Random number generator for various cryptographic functions

TlsClientProtocol

public TlsClientProtocol(java.security.SecureRandom secureRandom)

Constructor for non-blocking mode.

When data is received, use #offerInput(java.nio.ByteBuffer) to provide the received ciphertext, then use TlsProtocol.readInput(byte[], int, int) to read the corresponding cleartext.

Similarly, when data needs to be sent, use TlsProtocol.offerOutput(byte[], int, int) to provide the cleartext, then use TlsProtocol.readOutput(byte[], int, int) to get the corresponding ciphertext.

Parameters:

secureRandom - Random number generator for various cryptographic functions

Method Detail

connect

public void connect(TlsClient tlsClient)
             throws java.io.IOException

Initiates a TLS handshake in the role of client.

In blocking mode, this will not return until the handshake is complete. In non-blocking mode, use TlsPeer.notifyHandshakeComplete() to receive a callback when the handshake is complete.

Parameters:

tlsClient - The TlsClient to use for the handshake.

Throws:

java.io.IOException - If in blocking mode and handshake was not successful.

cleanupHandshake

protected void cleanupHandshake()

Overrides:
