They contain user ID, tenant ID, and roles. + +**Q: What's the difference between Bearer and Header auth?** +A: Both support JWT. Bearer auth is more standard for REST APIs. Header auth is for cases where Bearer auth can't be used (CORS, etc). + +**Q: Can I use this API from a browser?** +A: Yes! CORS is enabled. However, storing JWT in localStorage is a security risk. Use httpOnly cookies instead. + +**Q: What happens if my token expires?** +A: You'll receive a 401 response. Get a new token from the auth service and retry. + +**Q: How do I handle timeouts?** +A: Set timeouts in your HTTP client (30s recommended). Implement exponential backoff for retries. + +**Q: Is there a WebSocket API?** +A: Not in Phase 8. The REST API with polling is sufficient for most use cases. WebSocket support could be added in Phase 9. + +**Q: How do I deprecate a custom endpoint I added?** +A: Follow the 60-day deprecation cycle documented in the versioning section. + +## Next Steps + +**Phase 9 (Future):** +- WebSocket API for real-time updates +- GraphQL endpoint as alternative to REST +- SDK auto-update pipeline +- Enhanced analytics and monitoring +- Performance optimization (caching, indexing) + +## References + +- [OpenAPI 3.0.3 Specification](https://spec.openapis.org/oas/v3.0.3) +- [Swagger UI Documentation](https://swagger.io/tools/swagger-ui/) +- [OpenAPI Generator](https://openapi-generator.tech/) +- [ReDoc Documentation](https://redoc.ly/) +- [REST API Best Practices](https://restfulapi.net/) +- [API Versioning Strategies](https://www.troyhunt.com/your-api-versioning-is-wrong-which-is/) + +--- + +**Status**: ✅ Phase 8 COMPLETE - Production-ready OpenAPI documentation diff --git a/services/email_service/POP3_FILES_INDEX.md b/services/email_service/POP3_FILES_INDEX.md new file mode 100644 index 000000000..cfa8859a2 --- /dev/null +++ b/services/email_service/POP3_FILES_INDEX.md @@ -0,0 +1,351 @@ +# POP3 Protocol Handler - Complete File Index + +## Core Implementation Files + +### 1.

Workflow Engine Integration + +The plugin hooks into the MetaBuilder workflow engine: + +```typescript +// Registered in workflow/plugins/registry/ +export const ENCRYPTION_NODE = { + nodeType: 'encryption', + category: 'email-integration', + executor: encryptionExecutor, + parameterSchema: { + type: 'object', + properties: { + operation: { enum: ['encrypt', 'decrypt', 'sign', 'verify', 'import-key', 'export-key'] }, + algorithm: { enum: ['PGP', 'S/MIME', 'AES-256-GCM', 'RSA-4096', 'ECC-P256'] }, + messageId: { type: 'string' }, + content: { type: 'string' } + // ... additional properties + } + }, + inputs: [ + { name: 'main', type: 'main', maxConnections: 1 }, + { name: 'error', type: 'error', maxConnections: 1 } + ], + outputs: [ + { name: 'success', type: 'success', dataTypes: ['EncryptionResult'] }, + { name: 'error', type: 'error', dataTypes: ['Error'] } + ] +}; +``` + +### 3. Email Plugin Integration + +Update the email plugin index to export encryption executor: + +```typescript +// In workflow/plugins/ts/integration/email/index.ts +export { + encryptionExecutor, + EncryptionExecutor, + type EncryptionConfig, + type EncryptionResult, + type EncryptionMetadata, + type SignatureVerification, + type PublicKeyRecord, + type PrivateKeyRecord +} from './encryption/src/index'; +``` + +### 4. Message Processing Pipeline + +Wire encryption into the email message pipeline: + +```typescript +// In email-parser or draft-manager +import { encryptionExecutor, type EncryptionConfig } from '@metabuilder/workflow-plugin-encryption'; + +// Before sending message +const encryptionConfig: EncryptionConfig = { + operation: 'encrypt', + algorithm: 'PGP', + messageId: message.id, + content: message.body, + recipients: message.to, + publicKey: // fetch from key management +}; + +const encryptionResult = await encryptionExecutor.execute(encryptNode, context, state); + +if (encryptionResult.status === 'success') { + message.encryptedBody = encryptionResult.output.data.content; + message.encryptionMetadata = encryptionResult.output.data.metadata; +} +``` + +## Extending the Plugin + +### Adding New Algorithms + +To add a new encryption algorithm: + +1. **Define algorithm type**: +```typescript +export type EncryptionAlgorithm = 'PGP' | 'S/MIME' | 'AES-256-GCM' | 'RSA-4096' | 'ECC-P256' | 'YOUR_ALGORITHM'; +``` + +2. **Implement cipher selection**: +```typescript +private _selectSymmetricCipher(algorithm: EncryptionAlgorithm): string { + switch (algorithm) { + case 'YOUR_ALGORITHM': + return 'YOUR_CIPHER_NAME'; + // ... rest + } +} +``` + +3. **Add encryption logic**: +```typescript +private async _encryptWithYourAlgorithm( + content: string, + sessionKey: string, + config: EncryptionConfig +): Promise { + // Implementation using your crypto library +} +``` + +4. **Add validation**: +```typescript +if (node.parameters.algorithm === 'YOUR_ALGORITHM') { + // Your algorithm-specific validation +} +``` + +### Integration with External Key Servers + +Add key server integration for automatic key retrieval: + +```typescript +// In _encryptContent() method +private async _fetchPublicKeyFromServer( + email: string, + keyServer: string +): Promise { + // Implement key server lookup (SKS, X.500, etc.) + const response = await fetch( + `${keyServer}/api/v1/keys?email=${email}` + ); + const keyData = await response.json(); + return keyData.publicKey; +} +``` + +### Hardware Security Module (HSM) Support + +Extend for HSM-based key operations: + +```typescript +interface HSMConfig { + endpoint: string; + authentication: 'mTLS' | 'API_KEY'; + keyLabel: string; +} + +private async _signWithHSM( + contentHash: string, + hsmConfig: HSMConfig +): Promise { + // Send signature request to HSM + const response = await fetch(`${hsmConfig.endpoint}/sign`, { + method: 'POST', + body: JSON.stringify({ contentHash, keyLabel: hsmConfig.keyLabel }) + });

+``` + +2. **Secure Key Deletion**: +```typescript +// Overwrite key material from memory +private _secureDelete(data: string): void { + const buffer = Buffer.from(data); + buffer.fill(0); +} +``` + +3. **Access Control**: +```typescript +// Verify tenant ownership before decryption +const key = await dbal.privateKeys.get(keyId); +if (key.tenantId !== context.tenantId) { + throw new Error('Unauthorized key access'); +} +``` + +### Passphrase Handling + +1. **Key Derivation**: +```typescript +// Use PBKDF2 or Argon2 +const derivedKey = await scrypt(passphrase, salt, keyLength, { + N: 16384, + r: 8, + p: 1 +}); +``` + +2. **Secure Comparison**: +```typescript +// Use constant-time comparison +const match = crypto.timingSafeEqual( + computed, + provided +); +``` + +## Testing Strategy + +### Unit Tests Coverage + +- Algorithm selection +- Encryption/decryption correctness +- Signature creation/verification +- Key import/export parsing +- Error handling for all operations +- Metadata generation + +### Integration Tests + +- End-to-end encryption/decryption with real keys +- Multi-recipient encryption scenarios +- Signature chain verification +- Key management persistence +- Multi-tenancy isolation + +### Example Test + +```typescript +it('should encrypt and decrypt message successfully', async () => { + // Generate test key pair + const { publicKey, privateKey } = await generateKeyPair(); + + // Encrypt + const encryptNode = createMockNode({ + operation: 'encrypt', + content: TEST_MESSAGE, + recipients: [TEST_EMAIL], + publicKey + }); + const encrypted = await executor.execute(encryptNode, context, state); + + // Decrypt + const decryptNode = createMockNode({ + operation: 'decrypt', + content: encrypted.output.data.content, + privateKey, + verifySignature: false + }); + const decrypted = await executor.execute(decryptNode, context, state); + + expect(decrypted.output.data.content).toBe(TEST_MESSAGE); +}); +``` + +## Performance Optimization + +### Caching Strategies + +```typescript +// Cache frequently-used public keys +private keyCache = new Map(); + +private async _getPublicKey(email: string, tenantId: string): Promise { + const cacheKey = `${tenantId}:${email}`; + if (this.keyCache.has(cacheKey)) { + return this.keyCache.get(cacheKey)!; + } + + const key = await dbal.publicKeys.get(email, tenantId);

+ ``` + +2. **Configure Key Servers** (optional): + ```typescript + const KEY_SERVERS = { + pgp: 'https://keys.openpgp.org', + smime: 'ldap://x500.company.com' + }; + ``` + +3. **Set Trust Defaults**: + ```typescript + const DEFAULT_TRUST_LEVEL: TrustLevel = 'unverified';
