This project provides Rust libraries, command line tools and a test suite to interact with the File Hierarchy for the Verification of OS Artifacts (VOA). The VOA specification has been created to provide the means for a generic, OS artifact verification scheme, that can work with different technologies while relying on a unifying lookup directory to retrieve verifiers for signatures. This project provides a reference implementation for the VOA specification as well as a canonical test suite that is usable by any other implementation.
