CryptoTools is a portable c++14 library containing a collection of tools for building cryptographic protocols. This include asynchronous networking (Boost Asio), several fast primitives such as AES (AES-NI), Blake2 (assembly), and eliptic curve crypto (Relic-Toolkit, Miracl, or libsodium). There are also several other utilities tailored for implementing protocols.

Thirdparty networking is also supported. See frontend_cryptoTools/tutorial/Network.cpp for an example.

Build

The library is cross platform and has been tested on Windows, Mac and Linux. There is one mandatory dependency on Boost 1.75 (networking), and optional dependency on Relic. CMake 3.18+ is required and the build script assumes python 3.

git clone https://github.com/ladnir/cryptoTools
cd cryptoTools
python build.py --setup --boost --relic
python build.py -D ENABLE_RELIC=ON

It is possible to build only the protocol(s) that are desired via cmake command. In addition, if boost and or relic are already installed, then boost or relic can be ommitted from python build.py setup boost relic.

See the output of python build.py or cmake . for available compile options. For example,

python build.py -D ENABLE_SSE=OFF

will build without SSE instrisics. Argument after the -- are forwarded to cmake.

The main executable with examples is frontend and is located in the build directory, eg out/build/linux/frontend/frontend_cryptoTools, out/build/x64-Release/frontend/Release/frontend_cryptoTools.exe depending on the OS.

Enabling/Disabling dependancies:

• The library can be built without Relic as

python build.py --setup --boost
python build.py -D -D ENABLE_RELIC=OFF

• The library can be built without Boost as

python build.py --setup --relic
python build.py -D -D ENABLE_BOOST=OFF

Install

cryptoTools can be installed and linked the same way as other cmake project. By default the dependancies are not installed. To install then, run the following

python build.py --setup --boost --relic --install

You can also provide and install location by specifying --install=path/to/installation.

The main library is similarly installed as

python build.py --install 

By default, sudo is not used. If installation requires sudo access, then call

python build.py --install --sudo

See python build.py --help for full details.

Linking

cryptoTools can be linked via cmake as

find_package(cryptoTools REQUIRED)

target_link_libraries(myProject oc::cryptoTools)

Other exposed targets are oc::tests_cryptoTools. In addition, cmake variables cryptoTools_LIB, cryptoTools_INC, ENABLE_XXX will be defined when found, where XXX is one of the cryptoTools options.

To ensure that cmake can find cryptoTools, you can either install cryptoTools or build it locally and include cryptoTools in the CMAKE_PREFIX_PATH variable or provide its location as a cmake HINTS.
