This commit addresses critical issues preventing user registration:
1. Simplified Frontend Password Validation
- Changed from 8+ chars with uppercase, digit, special char
- To simple 6+ character requirement
- Matches user expectations and backend capability
2. Fixed Backend Password Constraint
- Updated VoterRegister schema min_length from 8 to 6
- Now consistent with simplified frontend validation
3. Fixed Frontend Proxy Routes Architecture
- Changed from using NEXT_PUBLIC_API_URL (build-time only)
- To using BACKEND_URL env var with Docker service fallback
- Now: process.env.BACKEND_URL || 'http://nginx:8000'
- Works both locally (localhost:8000) and in Docker (nginx:8000)
4. Simplified All Proxy Route Code
- Removed verbose comments
- Consolidated header construction
- Better error messages showing actual errors
- Applied consistent pattern to all 9 routes
Root Cause Analysis:
- Frontend container trying to reach localhost:8000 failed
- Docker containers can't use localhost to reach host services
- Must use service name 'nginx' within Docker network
- NEXT_PUBLIC_API_URL only works at build time, not runtime
Testing:
✅ Backend registration endpoint works (tested with Python requests)
✅ Password validation simplified and consistent
✅ Proxy routes now use correct Docker service URLs
Files Changed:
- frontend/lib/validation.ts (password requirements)
- backend/schemas.py (password min_length)
- 9 frontend proxy route files (all simplified and fixed)

This commit completes the voting system implementation with:
1. Frontend API Proxy Routes:
- Created 9 Next.js API routes to proxy backend requests
- Elections endpoints: /api/elections/*, /api/elections/{id}/*
- Votes endpoints: /api/votes/*, /api/votes/submit/*, etc.
- Auth endpoints: /api/auth/register/*, /api/auth/login/*, /api/auth/profile/*
- Fixed Next.js 15.5 compatibility with Promise-based params
2. Backend Admin API:
- Created /api/admin/fix-elgamal-keys endpoint
- Created /api/admin/elections/elgamal-status endpoint
- Created /api/admin/init-election-keys endpoint
- All endpoints tested and working
3. Database Schema Fixes:
- Fixed docker/create_active_election.sql to preserve ElGamal parameters
- All elections now have elgamal_p=23, elgamal_g=5 set
- Public keys generated for voting encryption
4. Documentation:
- Added VOTING_SYSTEM_STATUS.md with complete status
- Added FINAL_SETUP_STEPS.md with setup instructions
- Added fix_elgamal_keys.py utility script
System Status:
✅ Backend: All 3 nodes operational with 12 elections
✅ Database: ElGamal parameters initialized
✅ Crypto: Public keys generated for active elections
✅ API: All endpoints verified working
✅ Frontend: Proxy routes created (ready for rebuild)
Next Step: docker compose up -d --build frontend

Moved specific routes (/blockchain, /debug/all, /active, /completed, /upcoming)
BEFORE generic routes (/{election_id}, /{election_id}/results, etc) so that
specific paths are matched first and don't get caught by the {election_id}
path parameter matcher.
Also removed duplicate /completed and /upcoming route definitions.
Routes now in correct order:
1. Specific paths: /debug/all, /active, /blockchain
2. Specific subpaths: /{id}/blockchain-verify, /{id}/candidates, /{id}/results
3. Generic: /{id}
The main.py was trying to import get_db for blockchain initialization
but it was missing from database.py. Added the get_db generator function
that creates and properly closes database sessions.
Restores all missing project files and fixes:
- Restored backend/blockchain.py with full blockchain implementation
- Restored backend/routes/votes.py with all API endpoints
- Restored frontend/components/voting-interface.tsx voting UI
- Fixed backend/crypto/hashing.py to handle both str and bytes
- Fixed pyproject.toml for Poetry compatibility
- All cryptographic modules tested and working
- ElGamal encryption, ZK proofs, digital signatures functional
- Blockchain integrity verification working
- Homomorphic vote counting implemented and tested
Phase 2 Backend API: ✓ COMPLETE
Phase 3 Frontend Interface: ✓ COMPLETE
Verification:
✓ Frontend builds successfully (12 routes)
✓ Backend crypto modules all import correctly
✓ Full voting simulation works end-to-end
✓ Blockchain records and verifies votes
✓ Homomorphic vote counting functional

- Added HistoriquePage component to display user's voting history with detailed statistics and vote cards.
- Created UpcomingVotesPage component to show upcoming elections with a similar layout.
- Developed CSS styles for both pages to enhance visual appeal and responsiveness.
- Integrated API calls to fetch user's votes and upcoming elections.
- Added a rebuild script for Docker environment setup and data restoration.
- Created a Python script to populate the database with sample data for testing.
