libsignal-protocol-c | ratcheting forward secrecy protocol | Networking library

Most of these dependencies are required just for the unit test suite and development of the library itself. When integrating into actual applications, you should not need anything beyond CMake. Alternatively, you may integrate the code using a build system of your choice. Items marked with *1 are required for tests, with *2 are additionally required for code coverage.
CMake 2.8.4 or higher
Check *1
OpenSSL *1 1.0 or higher
On MacOS X, Common Crypto is used instead of OpenSSL
LCOV *2
CMake provides a tutorial on Eclipse project setup here: https://cmake.org/Wiki/CMake:Eclipse_UNIX_Tutorial. It is recommended to follow the more manual "Option 2," since the Eclipse project generator built into CMake tends to be outdated and leads you toward a very awkward and occasionally broken project configuration.
At install time, a libsignal-protocol-c client needs to generate its identity keys, registration id, and prekeys. The above example is simplified for the sake of clarity. All of these functions return errors on failure, and those errors should be checked for in real usage. There are also iteration and serialization methods for the above types that should be used as appropriate.
