EMET

EMET is a lightweight, open-source CLI tool designed for meticulous file verification. Built under the MPL-2.0 license, it allows users to anchor the bytes of a file and later re-compute its SHA-256 hash to verify whether the file has remained unchanged or has been altered. Its primary audience includes developers, researchers, and reviewers who need a reliable method to confirm the integrity of AI-touched files, prompts, or viewed content. What sets EMET apart is its focused, byte-level verification approach, providing straightforward evidence without delving into semantic analysis or model safety concerns. This makes it an essential tool for those valuing byte integrity, audit trails, and source verification in AI workflows.
