SRTP Payload
by Hilman Fitriana 07 Jun '20

07 Jun '20

Hello, I want to ask about the payload from SRTP. Here I use the 128-bit AES_CM encryption feature. What I want to ask is for every srtp_protect / srtp_protect_mki function call, does that represent an SRTP packet? Then in the srtp_protect_mki module, the srtp_encrypt function will be called which is related to the srtp_aes_icm_encrypt function. Then what I want to ask is what is the payload size which is the parameter of the function? Will selection of the AES_CM_128 bit feature affect the payload length of each SRTP packet? Thank you

Hi, Version 2.2.0 of libsrtp is now released from the 2_2_x_throttle, https://github.com/cisco/libsrtp/tree/2_2_x_throttle . The major change with this release is that the all the code has been reformatted to be consistent and this consistency can be enforced with the include .clang-format file. This resulted in a lot of none functional changes but was considered worth it to simplify maintenance in the future. There are numerous other minor fixes, see the CHANGES file for more details The following links are available for downloading: https://github.com/cisco/libsrtp/archive/v2.2.0.tar.gz https://github.com/cisco/libsrtp/archive/v2.2.tar.gz https://github.com/cisco/libsrtp/archive/v2.tar.gz Thank you to everybody that has contributed. libSRTP team.

libsrtp version 1.6.0 hase been released
by Pascal Buhler (pabuhler) 01 Aug '17

01 Aug '17

Version 1.6.0 of libsrtp has now been released. This release restores compatibility between version 1 and version 2.1.0 and later. >From this point 1.5.x is effectively EOL and there will be no more changes to 1_5_x_throttle. It is strongly recommended for people currently using a 1.5.x release to move to the 1.6.0 release if they are unable to move the 2.1.0 release. The 1_6_x_throttle will only receive important security fixes. Regards The libsrtp maintenance team.

Hi, Version 2.1.0 of libsrtp is now released from the 2_1_x_throttle, https://github.com/cisco/libsrtp/tree/2_1_x_throttle . Please read the CHANGES file or look at the git log to get an overview of what has changed since 2.0.0 . The following links are available for downloading: https://github.com/cisco/libsrtp/archive/v2.1.0.tar.gz https://github.com/cisco/libsrtp/archive/v2.1.tar.gz https://github.com/cisco/libsrtp/archive/v2.tar.gz Going forward we would like to make two new release in the short time. 1.6.0 release that addresses compatibility issues with the 2.1.0 release and a 2.2.0 release that will focus mostly on cleaning up the code repository with for example consistent formatting of the code as well as try to close as many of the open issues as possible. Thank you to everybody that has contributed. libSRTP team.

brancing for 2.1.0 release
by Pascal Buhler (pabuhler) 24 May '17

24 May '17

Hi A 2_1_x_throttle branch has been created, this will be the base for the 2.1.0 release. There are no outstanding issues blocking this release so if no new issues are found then the plan is to release 2.1.0 by 1st June. It would be greatly appreciated if people take the time to test out this release now! Especially related to various platform support. The 2.1.0 release contains several fixes that make it potentially incompatible with the current 1.5.x release. Due to this there will be an accompanying 1.6.0 release to ensure that there is compatibility between the 1.x series and the latest 2.x version for those that cannot migrate to 2.1.0 for any reason. Regards libsrtp team.

Soliciting feedback on new AES-GCM related bug found in libSRTP 1.5.4 & 2.0.0
by Pascal Buhler (pabuhler) 23 Feb '17

23 Feb '17

Hi, The following bug was recently reported on github https://github.com/cisco/libsrtp/issues/256, this bug relates to AES-GCM on little-endian system. Fixing this bug will cause some backward compatibility issues with existing libSRTP version, but not fixing is not really an option due to interop issues with other AES-GCM implementations as well as it being a potential security problem. Current plan is to fix as part of the upcoming 2.1.0 release and then simultaneously create patch release for 1.5.x. If this bug affects your usage of libSRTP and you would like to discuss how a fix is released then please reply to this mail at libsrtp(a)lists.packetizer.com<mailto:libsrtp@lists.packetizer.com> or else comment directly on the github issue. pascal
