createSRTPConnector

public static TransformConnector createSRTPConnector(javax.media.rtp.SessionAddress addr,
                                                     byte[] masterKey,
                                                     byte[] masterSalt,
                                                     SRTPPolicy srtpPolicy,
                                                     SRTPPolicy srtcpPolicy)
                                              throws javax.media.rtp.InvalidSessionAddressException

Create a SRTP TransformConnector, which will provide SRTP encryption / decryption functionality, using algorithms defined in RFC3711.

Parameters:

addr - local RTP session listen address

masterKey - master key of this SRTP session

masterSalt - master salt of this SRTP session

srtpPolicy - SRTP policy for this SRTP session

srtcpPolicy - SRTCP policy for this SRTP session

Returns:

the TransformConnector used for SRTP encyption/decryption

Throws:

javax.media.rtp.InvalidSessionAddressException - if the local RTP session address is invalid

createZRTPConnector

public static TransformConnector createZRTPConnector(javax.media.rtp.SessionAddress addr)
                                              throws javax.media.rtp.InvalidSessionAddressException

Creates a connector specific for use in case of ZRTP key management

Parameters:

addr - local RTP session listen address

Returns:

the TransformConnector used for ZRTP processing

Throws:

javax.media.rtp.InvalidSessionAddressException

createDummyConnector

public static TransformConnector createDummyConnector(javax.media.rtp.SessionAddress addr)
                                               throws javax.media.rtp.InvalidSessionAddressException

Create a dummy TransformConnector. A dummy TransformConnector does no modification (transformation) to RTP/RTCP packets. Its main purpose is to test the TransformationConnector interface and provides a example code of how to use the TransformConnector interfaces.

Parameters:

addr - local RTP session address

Returns:

A dummy TransformationConnector object

Throws:

javax.media.rtp.InvalidSessionAddressException - if the local RTP session address is invalid
