libSRTP
An open-source C library implementing the Secure Real-time Transport Protocol (SRTP) for encrypting and authenticating RTP/RTCP media streams.
What is libSRTP?
libSRTP is an open-source C library that implements the Secure Real-time Transport Protocol (SRTP), an IETF standard profile for providing confidentiality, message authentication, and replay protection to Real-time Transport Protocol (RTP) traffic. It solves the problem of securing real-time media streams, such as those used in VoIP, video conferencing, and telephony, against eavesdropping and tampering.
Developers and engineers building secure real-time communication applications, including VoIP clients, video conferencing systems, streaming media servers, and embedded devices that handle RTP/RTCP traffic.
Developers choose libSRTP because it is a mature, widely deployed, and standards-compliant library that provides a robust and portable implementation of SRTP. Its support for multiple cryptographic backends, flexible session and stream policy management, and inclusion of both mandatory and advanced features (like AES-GCM) make it a reliable foundation for adding security to RTP-based applications.
