ElectionGuard is an open source software development kit (SDK) that makes voting more secure, transparent and accessible. Announced at the Build developer conference, ElectionGuard enables end-to-end verification of elections as well as support the publication of results from ballot comparison audits. The ElectionGuard SDK leverages homomorphic encryption to ensure that votes recorded by electronic systems of any type remain encrypted, secure, and secret. Results can be published online or made available to third-party organizations for secure validation, and allow individual voters to confirm their votes were correctly counted.

This library and all linked ElectionGuard projects, are licensed under the MIT license. There is no fee for using ElectionGuard.

ElectionGuard is always improving. To keep up with the latest, check our official site on GitHub Pages and our roadmap. For those looking to get started, we recommend the following repositories.

We encourage the developer and security community to conduct research, report issues, and suggest improvements on this code base. However, unlike performance or feature bugs, please do not report security vulnerabilities in public Github comments. Each repository has a SECURITY file with instructions on responsibly reporting security vulnerabilities under Microsoft's CVD process.
