OpenSSL SRTP
OpenSSL SRTP is a library extension within the OpenSSL cryptographic toolkit that implements the Secure Real-time Transport Protocol (SRTP) for encrypting and authenticating real-time media streams, such as voice and video in VoIP and WebRTC applications. It provides functions for key derivation, encryption, and integrity protection specifically tailored for RTP and RTCP packets, ensuring secure communication in multimedia sessions.
Developers should learn and use OpenSSL SRTP when building secure real-time communication systems, such as VoIP clients, video conferencing tools, or WebRTC-based applications, to protect media streams from eavesdropping and tampering. It is essential in scenarios requiring compliance with security standards like RFC 3711 for SRTP, offering a robust, open-source solution integrated with OpenSSL's broader cryptographic capabilities.
