This repository is a "reference implementation" of ElectionGuard written in Python 3. This implementation can be used to conduct End-to-End Verifiable Elections as well as privacy-enhanced risk-limiting audits. Components of this library can also be used to construct "Verifiers" to validate the results of an ElectionGuard election.

ElectionGuard is an open source software development kit (SDK) that makes voting more secure, transparent and accessible. The ElectionGuard SDK leverages homomorphic encryption to ensure that votes recorded by electronic systems of any type remain encrypted, secure, and secret. Meanwhile, ElectionGuard also allows verifiable and accurate tallying of ballots by any 3rd party organization without compromising secrecy or security.

ElectionGuard supports a variety of use cases. The Primary use case is to generate verifiable end-to-end (E2E) encrypted elections. The ElectionGuard process can also be used for other use cases such as privacy enhanced risk-limiting audits (RLAs).
- Python 3.9+ is required to develop this SDK. If developer uses multiple versions of python, pyenv is suggested to assist version management.
- GNU Make is used to simplify the commands and GitHub Actions. This approach is recommended to simplify the command line experience. This is built in for MacOS and Linux. For Windows, setup is simpler with Chocolatey and installing the provided make package. The other Windows option is manually installing make.
- Gmpy2 is used for Arbitrary-precision arithmetic which
has its own installation requirements (native C libraries) on Linux and MacOS.
⚠️ Note: This is not required for Windows since the gmpy2 precompiled libraries are provided. - poetry 1.1.10 is used to configure the python environment. Installation instructions can be found here.
Using make, the entire [GitHub Action workflow][pull request workflow] can be run with one command:
make
The unit and integration tests can also be run with make:
make test
A complete end-to-end election example can be run independently by executing:
make test-example
For more detailed build and run options, see the documentation.
