Next Steps

wolfCrypt Test Application

After getting wolfSSL proper to build on the target platform, a good next step is to port the wolfCrypt test application. Running this application on the target system will verify that all the crypto algorithms are working correctly, using NIST test vectors.

If this step is skipped, and you instead proceed directly to establishing an SSL connection, it can be more difficult to debug problems caused by underlying crypto operations failing.

The wolfCrypt test application is located in ./wolfcrypt/test/test.c. If an embedded application has its own main() function, then NO_MAIN_DRIVER must be defined when compiling ./wolfcrypt/test/test.c. This will allow the application's main() to call each cipher/algorithm test individually on its own.

If an embedded device does not have enough resources to run the entire wolfCrypt test application, individual tests can be broken out of test.c and compiled individually. Please ensure that correct header files needed for the specific test case are included in the build when extracting isolated crypto tests from test.c.
