• main.c : main entrypoint
• dsa_test.c : DSA test routine
• ecdsa_test.c : ECDSA test routine
• debug.c : helper function definitions
• prng_simulator.c (.h) : placeholder implementation of a PRNG
• lib/common : common files for CycloneCRYPTO (Open)
• lib/core : core files for CycloneCRYPTO (Open)
• lib/cyclone_crypto : complete source code for CycloneCRYPTO (Open)
• lib/crypto_config.h : used to enable/disable different CRYPTO modules
• lib/os_port_config.h : contains information about the target platform

Build

• create a 'build' directory at the project root.
• From within 'build' directory, execute the following commands:
  • cmake ..
  • cmake --build .
• ./dsa_ecdsa_signature_demo will run the demo.

About lib/ folder

This folder contains all the files/folders available for CycloneCRYPTO suite. Naturally, not all files/folders are used for this demo. lib/CMakeLists.txt contains a list of dependencies for the current project.
