C - Devolens (formerly Cryptolens) Documentation

We recommend to review the repository of the C client SDK for more examples: https://github.com/Cryptolens/cryptolens-c Below are build instructions. We recommend to use our C++ SDK when possible, since the it is has support for more methods.

Build instructions

Visual Studio

Build the project in vsprojects/Cryptolens with some platform and configuration (e.g. Win32 and Debug). This will create the Cryptolens.lib file in vsprojects/Cryptolens/Cryptolens/$(Configuration) or vsprojects/Cryptolens/Cryptolens/x64/$(Configuration) for platforms Win32 and x64, respectively. The Cryptolens.lib file can then be used in another project, together with the include files in the include/ directory. The examples/CryptolensExamples project is setup to build the example file examples/example_activate_external.c in this way. Thus, to build the example project, first build the library in vsprojects/Cryptolens and then build the example project in examples/CryptolensExamples.

CMake

There is a CMakeLists.txt in the root of the repository which can be used to build the library. The examples can be built using the CMakeLists.txt in examples/. The following commands, when ran from the root of the repository, builds the examples:

mkdir build
cd build
cmake ../examples
make

GCC/Clang

The example file can also be build manually with GCC or Clang using the following command (run from the root of the repository):

gcc -Iinclude/ -Ithird_party/cJSON/ src/cryptolens.c src/data_object.c src/decode_base64.c src/error.c src/machine_code_computer_static.c src/request_handler_curl.c src/response_parser_cJSON.c src/signature_verifier_openssl.c third_party/cJSON/cJSON.c third_party/openbsd/base64.c third_party/openbsd/strlcpy.c -lcrypto -lssl -lcurl examples/example_activate.c
