   npm run dev
   # Application runs at http://localhost:3000

Verification Scripts

Run these scripts to verify the integrity of the cryptographic implementation and backend services:

# Verify Base58 implementation and BigInt logic
node scripts/test-crypto.js

# Verify Backend Blockchain & Email APIs
# (Ensure backend is running on port 3001)
node scripts/verify-blockchain.js

# Verify DID Registry
node scripts/verify-did.js

Production Build

# Build for production

Add a New Command (Template)

When you add a new command, update this README with a row like this:

| `<command>` | `<what it does>` | `<PASS|FAIL|PARTIAL|NOT VERIFIED>` | `<how it works, required services/env, and last verification date>` |

Example:

| `npm run my:task` | Generates internal reports | NOT VERIFIED | Reads `./data`, writes `./reports`; requires `.env.local` |

API Documentation

Credential Issuance

import { blockchainManager } from './services/blockchainService';
import { zkProof } from './services/zkProof';
import { didService } from './services/didService';

// Issue a new credential
const credential = {
  studentId: 'STU123456',
  degree: 'Bachelor of Science',
  major: 'Computer Science',
  gpa: 3.85,
  graduationYear: 2024,
};

const zkProof = await zkProof.generateZKProof(credential);
const did = didService.generateDID('student', credential.studentId);
const txHash = await blockchainManager.issueCredential(credential, zkProof, did);

Credential Verification

// Verify a credential
const isValid = await blockchainManager.verifyCredential(credentialHash, zkProof, did);

console.log(`Credential valid: ${isValid}`);

Security Best Practices

1. Never commit .env.local - Contains sensitive API keys
2. Use HTTPS in production - Enable SSL/TLS
3. Enable MFA - Multi-factor authentication for all admin accounts
4. Regular audits - Run security audits quarterly
5. Update dependencies - Keep packages up to date
6. Disable client-side signing - Keep issuer keys in a secure backend
7. Proxy IPFS writes - Use VITE_IPFS_WRITE_MODE=proxy with a server-side pinning service
8. Monitor logs - Use Sentry/DataDog for error tracking
9. Rate limiting - Protect against DDoS attacks
10. Input validation - Sanitize all user inputs
