Class SRTPTransformEngine

java.lang.Object
  net.java.sip.communicator.impl.neomedia.transform.srtp.SRTPTransformEngine

All Implemented Interfaces:

TransformEngine

public class SRTPTransformEngine
extends Object
implements TransformEngine

SRTPTransformEngine class implements TransformEngine interface. It stores important information / objects regarding SRTP processing. Through SRTPTransformEngine, we can get the needed PacketTransformer, which will be used by abstract TransformConnector classes.

Constructor Detail

SRTPTransformEngine

public SRTPTransformEngine(byte[] masterKey,
                           byte[] masterSalt,
                           SRTPPolicy srtpPolicy,
                           SRTPPolicy srtcpPolicy)

Construct a SRTPTransformEngine based on given master encryption key, master salt key and SRTP/SRTCP policy.

Parameters:

masterKey - the master encryption key

masterSalt - the master salt key

srtpPolicy - SRTP policy

srtcpPolicy - SRTCP policy

Method Detail

close

public void close()

Close the transformer engine. The close functions closes all stored default crypto contexts. This deletes key data and forces a cleanup of the crypto contexts.

getRTCPTransformer

public PacketTransformer getRTCPTransformer()

Gets the PacketTransformer for RTCP packets.

Specified by:

getRTCPTransformer in interface TransformEngine

Returns:

getRTPTransformer

public PacketTransformer getRTPTransformer()

Description copied from interface: TransformEngine

Specified by:

getRTPTransformer in interface TransformEngine

Returns:

the PacketTransformer for RTP packets

getDefaultContext

public SRTPCryptoContext getDefaultContext()

Get the default SRTPCryptoContext

Returns:

the default SRTPCryptoContext

getDefaultContextControl

public SRTCPCryptoContext getDefaultContextControl()

Get the default SRTPCryptoContext

Returns:

the default SRTPCryptoContext
