From 74d4f474ee90ebe665ef98278905e65da9ffde41 Mon Sep 17 00:00:00 2001 From: udaycodespace Date: Mon, 9 Mar 2026 21:07:01 +0530 Subject: [PATCH 01/15] feat(portal): UI overhaul, RBAC security, and secure system purge workflow Redesigned Issuer, Student, and Verifier portals with improved UI consistency. Implemented role-based navigation restrictions and Email OTP MFA with masked notifications. Added HTML email templates for authentication and security alerts. Secured system purge with multi-step verification and encrypted PDF audit reports. Refactored backend logic across app.py, models.py, mailer.py, and portal templates. --- app/app.py | 346 +++++++++++++++++++++++-------- app/models.py | 40 ++-- commit_msg.txt | 11 - core/mailer.py | 151 ++++++++++++++ templates/base.html | 146 ++++++++++--- templates/holder.html | 46 +++- templates/issuer.html | 449 +++++++++++++++++++++++++--------------- templates/login.html | 125 ++++++++--- templates/verifier.html | 23 +- 9 files changed, 994 insertions(+), 343 deletions(-) delete mode 100644 commit_msg.txt diff --git a/app/app.py b/app/app.py index 7428a47..a592f6f 100644 --- a/app/app.py +++ b/app/app.py @@ -40,6 +40,8 @@ from reportlab.pdfgen import canvas from reportlab.lib.pagesizes import letter from reportlab.lib import colors +from reportlab.lib.units import inch +from PyPDF2 import PdfReader, PdfWriter from flask import send_file # FIXED: Flask app with ROOT-LEVEL template/static paths @@ -127,37 +129,51 @@ def handle_login_request(portal_role=None): flash(f'🔐 Access Denied: This is the {portal_name} portal.
