A modern, dependency-free, pure-Java implementation of SRTP and SRTCP (RFC 3711, RFC 6188 and RFC 7714). It encrypts and authenticates RTP/RTCP packets with AES-CM or AES-GCM and HMAC-SHA1, deriving session keys through the standard JDK Key Derivation Function API, with no native code and no third-party runtime dependencies.
