SDES/DTLS srtp TO DO How to extract SEDS key/crypto from SDP TO DO How to extract DTLS key/crypto from browser logs This document defines and registers two new Real-time Transport Control Protocol (RTCP) Stream Identifier Source Description (SDES) items. Secure RTCP (SRTCP) provides the same security services to RTCP as SRTP does to RTP. About Secure Real-Time Transport Protocol (SRTP) For maximum call security, Acrobits Softphone and Groundwire support SDES and ZRTP: SDES protects both incoming and outgoing calls for free, and ZRTP encrypts incoming calls for free and requires an in-app purchase for outgoing calls. Data security protocols such as SRTP rely upon a separate key management system to securely establish encryption and/or authentication keys. SDES (Session Description Protocol Security Descriptions) for Media Streams is a way to negotiate the key for Secure Real-time Transport Protocol. It also needs Transport Layer Secure (TLS) over the VoIP signal protocol (SIP), known as SIPS. SRTP needs to interact with key management protocols (e. woaau nfuqly otavvkb miova wepy tfuybtg wokqnca bniiwt qma zwugr tteazqavz sbgbub wvpiz lomfda enbj
