How gamingforce466-collab/digisign-15 works

DigiSign is a web application for creating RSA-PSS digital signatures on supported documents and verifying their integrity and embedded QR metadata. The principal workflow is key creation, document upload and signing, format-specific QR/metadata embedding, then verification; users can add multiple signers. Flask and Streamlit provide interfaces, while a shared workflow coordinates crypto, document-format dispatch, QR generation, and persisted records. README also documents benchmarking/export, demo data, and storage cleanup. Streamlit wiring and several secondary services were not excerpted, so those connections are shown only where documented or indexed.
