## Overview

CERTIFYME is a Flask certificate-management application. Teachers register and sign in, upload certificate files, and issue certificates; students access certificates through verification codes and protected shareable links. The application also provides student/admin authentication and an admin dashboard with audit and upload views. The sampled application code confirms SQLite access, teacher-gated uploads, verification-code lookup, and audit logging; upload processing and link-generation details are not visible in the excerpts, so their internal wiring is kept high-level. The pip and vendored-library files are environment dependencies, not product components.

Main entry points: [`app.py`](https://github.com/thangallapallysiddu-10/certify-me/blob/main/app.py) (Web application)
