Hi all, We are using freeswitch for handling webrtc calls and the negotiation in DTLS mode. We are looking for a tool to decrypt the traffic between the webrtc client and freeswitch server. I know there is already a tool pcaputils from PJSIP for decrypting the SRTP traffic. Since we are using in DTLS mode we can't use this. Can any one suggest any tool/method to decrypt the webrtc audio? Regards Varghese Paul
Look into rtpengine and perhaps Kamailio to control it. On 30 October 2014 04:41, Varghese Paul <varghesepaul87@gmail.com> wrote:

rtpengine doesn't provide any mean to do any kind of decryption. The keys, however, are easily accessible if you are willing to modify the original software to create such functionality. Regards, Carlos On Thu, Oct 30, 2014 at 10:47 AM, Anthony Minessale < anthony.minessale@gmail.com> wrote:

rtpengine does indeed allow decryption of DTLS encrypted RTP. I use it in front of Asterisk 1.4 for exactly that (and ICE resolution). On 30 October 2014 14:55, Carlos Ruiz Díaz <carlos.ruizdiaz@gmail.com> wrote:

The way I use rtpengine, it rewrites SDP between the browser and Asterisk 1.4, terminating DTLS and ICE. Between the browser and rtpengine is RTP/SAVPF, while between rtpengine and Asterisk is RTP/AVP. rtpengine generates its keys in what I assume to be the same way the browsers do.

What I believe the OP is looking for is a tool to extract audio from native pcaps of a DTLS RTP stream found therein. pcaputils is such a program but it needs the key as a command line param. in FS we don't display the keys from the DTLS negotiation because it defeats the point of why its secure. So what we would need is a secure practice to log the keys so they could be used later to run pcaputils. It would involve a setting to log the keys to the cdr which is much less secure than the intended point of DTLS audio. Its a question of responsibility to the security movement and weather or not its a good idea to open the door to nullifying the security. It could be justified that it's ok if the user chooses to enable it but typically the security community frowns on any ways to actively disable security. Obviously, FS could just bridge the encrypted RTP to another decrypted endpoint and record the call on its own as proposed with RTPengine but its not quite the same as extracting the original audio from a pcap containing encrypted data.

Maybe when enabled the key could be logged to CDR encrypted with a passphrase. Asking for a new passphrase on every startup would mean the FS start must be assisted by someone and hopefully this would discourage the continuous use. I'm not sure there is a use case that would justify the effort though. What is the use case by the way? Check audio quality? Best. <http://www.tuntscorp.com> *Wesley Akio* *Sr. Software Engineer* Av.

What I believe the OP is looking for is a tool to extract audio from native pcaps of a DTLS RTP stream found therein. pcaputils is such a program but it needs the key as a command line param.
in FS we don't display the keys from the DTLS negotiation because it defeats the point of why its secure. So what we would need is a secure practice to log the keys so they could be used later to run pcaputils. It would involve a setting to log the keys to the cdr which is much less secure than the intended point of DTLS audio. Its a question of responsibility to the security movement and weather or not its a good idea to open the door to nullifying the security. It could be justified that it's ok if the user chooses to enable it but typically the security community frowns on any ways to actively disable security.
Obviously, FS could just bridge the encrypted RTP to another decrypted endpoint and record the call on its own as proposed with RTPengine but its not quite the same as extracting the original audio from a pcap containing encrypted data.

Hi Akio, Yes the use case is to check the audio quality. Regards Varghese Paul On Sun, Nov 2, 2014 at 2:58 AM, Ben Langfeld <ben@langfeld.co.uk> wrote:
Ah, this is not what I understood from the original question. My apologies for the detour.

Hi Ben,
I am looking for a tool like wireshark to decrypt the SRTP packets and listen to the audio. RTPengine as you said we can bridge two channels and we can't use it as a tool for decrypting SRTP traffic,
Regards

I understand that this is not what he is intending. Why would he need yet another rtp bridge if FS already does exactly that. On Oct 31, 2014 7:36 AM, "Ben Langfeld" <ben@langfeld.co.uk> wrote:
The way I use rtpengine, it rewrites SDP between the browser and Asterisk 1.4, terminating DTLS and ICE. Between the browser and rtpengine is RTP/SAVPF, while between rtpengine and Asterisk is RTP/AVP. rtpengine generates its keys in what I assume to be the same way the browsers do.

The tool from pjsip mentioned above requires the keys for the srtp decryption. Does the one you mention do it differently?

Anthony, I think I'm not understanding your concern. Could you explain what you mean by logging the keys?
