libSRTP
libSRTP is an open-source C library that provides an implementation of the Secure Real-time Transport Protocol (SRTP) and its associated key management protocol, Secure RTCP (SRTCP). It is designed to secure real-time communication applications, such as voice over IP (VoIP) and video conferencing, by encrypting and authenticating RTP/RTCP packets. The library is widely used in multimedia applications to ensure confidentiality, integrity, and replay protection for streaming media.
Developers should learn and use libSRTP when building real-time communication systems that require secure transmission of audio and video data, such as in VoIP clients, video conferencing tools, or WebRTC applications. It is essential for implementing SRTP/SRTCP standards to protect against eavesdropping and tampering in network environments, making it a critical component for applications that handle sensitive media streams over the internet.
