Building instructions for Autotools

$ sudo apt-get install m4 autoconf automake libtool make gcc curl
$ curl https://sh.rustup.rs -sSf | sh

$ git clone https://github.com/mesalock-linux/mesalink.git
$ ./autogen.sh --enable-examples
$ make

Building instructions for CMake

$ sudo apt-get install cmake make gcc curl

$ git clone https://github.com/mesalock-linux/mesalink.git
$ mkdir build && cd build
$ cmake ..
$ cmake --build .

Examples

MesaLink comes with two examples that demonstrate a TLS client and a TLS server. Both of them are located at examples/.

The client example connects to a remote HTTPS server and prints the server's response.

The server example comes with a pair of certificate and private key. The certificate file is in the PEM format and contains a chain of certificates from the server's certificate to the root CA certificate. The private key file contains a PKCS8-encoded private key in the PEM format. Once the server is up and running, open https://127.0.0.1:8443 and expect to see the hello message.

Unit tests

MesaLink uses cargo for unit tests. Simply run cargo test.

$ cargo test

BoringSSL SSL tests

BoGo is BoringSSL's protocol level test suite. We have ported BoGo for testing the functionality and compatibility of MesaLink. To run BoGo test cases, run the following:

$ cd bogo && ./runme
