It leverages the modular extension technique, which was developed to protect embedded cryptographic implementations against fault injection attacks, to ensure the integrity of a computation delegated to an untrusted third-party.
You can probably install it using your distribution's package manager: it's the python3-pycryptodome package on Debian and derivatives.
If you choose to let pip install pycryptodomex, you will need to have some Python development packages installed as it needs to compile C extensions. On Debian and derivatives, the necessary packages are named python3-dev and python3-wheel.
In addition to the previously mentioned test demo of THC, an electronic voting software (server and client) is provided in the thc.demo.evoting package.
