Jitsi SRTP

Jitsi SRTP contains classes for encrypting and decrypting SRTP and SRTCP packets.

Building with Java changes only

To avoid having to build all native libraries, execute resources/fetch-maven.sh to download and extract the native binaries from the latest release on Maven Central.

Building the native libraries

Jitsi SRTP contains native libraries to speed up encryption/decryption. The artifacts released to Maven Central contain pre-built binaries for Ubuntu for OpenSSL 1.1 and 3.

Please take a look at the GitHub Actions build before asking for more detailed build instructions!

Ubuntu

Prerequisites:

• OpenJDK 11 (or newer)
• Maven
• Docker

Run mvn compile to generate the JNI headers, then run resources/ubuntu-build-all.sh. The script creates Docker images for each architecture and OpenSSL version.

Mac

Prerequisites:

• OpenJDK 11 (or newer) for the intended architectures
• XCode
• CMake
• Maven
• OpenSSL (intended version and architecture)

Run mvn compile to generate the JNI headers, then run resources/mac-cmake.sh .
