JWT Bearer Authentication - COMPLETE ✅

All three core services now have JWT Bearer authentication integrated with the Tenant Service.

Blueprint Service Authentication ✅

Implementation: src/Services/Sorcha.Blueprint.Service/Extensions/AuthenticationExtensions.cs

• ✅ JWT Bearer token validation
• ✅ Token issuer: https://tenant.sorcha.io
• ✅ Token audience: https://api.sorcha.io
• ✅ Symmetric key signing (HS256)
• ✅ 5-minute clock skew tolerance
• ✅ Authentication logging

Authorization Policies:

Policy	Description	Requirements
CanManageBlueprints	Create, update, delete blueprints	org_id OR service token
CanExecuteBlueprints	Execute blueprint actions	Authenticated user
CanPublishBlueprints	Publish blueprints	can_publish_blueprint OR Administrator
RequireService	Service-to-service operations	token_type=service

Protected Endpoints:

• /api/blueprints - Blueprint management
• /api/blueprints/{id}/execute - Action execution

---

Wallet Service Authentication ✅

Implementation: src/Services/Sorcha.Wallet.Service/Extensions/AuthenticationExtensions.cs

• ✅ JWT Bearer token validation
• ✅ Shared JWT configuration
• ✅ Authentication logging

Authorization Policies:

Policy	Description	Requirements
CanManageWallets	Create, list wallets	org_id OR service token
CanUseWallet	Sign, encrypt, decrypt	Authenticated user
RequireService	Service-to-service ops	token_type=service

Protected Endpoints:

• /api/v1/wallets - Wallet management
• /api/v1/wallets/{id}/sign - Signing operations
• /api/v1/wallets/{id}/encrypt - Encryption operations

---

Register Service Authentication ✅

Implementation: src/Services/Sorcha.Register.Service/Extensions/AuthenticationExtensions.cs

• ✅ JWT Bearer token validation
• ✅ Shared JWT configuration
• ✅ Authentication logging

Authorization Policies:

Policy	Description	Requirements
CanManageRegisters	Create/configure registers	org_id OR service token
CanSubmitTransactions	Submit transactions	Authenticated user
CanReadTransactions	Query transactions	Authenticated user
RequireService	Service-to-service notifications	token_type=service
RequireOrganizationMember	Organization member ops	org_id claim

Protected Endpoints:

• /api/registers - Register management
• /api/registers/{registerId}/transactions - Transaction submission
• /api/query/* - Query APIs
• /api/registers/{registerId}/dockets - Docket queries

Documentation

File: docs/guides/AUTHENTICATION-SETUP.md (364 lines)

• ✅ Architecture overview with service diagram
• ✅ Configuration guide for all services
• ✅ Authentication flows (user login, service-to-service OAuth2)
• ✅ Token claims structure (user tokens, service tokens)
• ✅ Testing procedures with curl examples
• ✅ Authorization policy reference tables
• ✅ Troubleshooting guide (401/403 errors, token validation)

API Gateway JWT Validation - COMPLETE ✅

Implementation: src/Services/Sorcha.ApiGateway/Program.csCompleted: 2026-01-31

• ✅ JWT Bearer token validation at gateway level
• ✅ Shared JWT settings via ServiceDefaults
• ✅ Authentication middleware in request pipeline
• ✅ Protected endpoints return 401 without valid tokens
• ✅ Public endpoints (health, stats) remain accessible
• ✅ Automatic token forwarding to backend services via YARP

Configuration:

• JWT settings configured via docker-compose environment variables
• Uses shared JWT signing key across all services (x-jwt-env)
• Issuer: http://localhost (via JwtSettings__InstallationName)
• Authentication integrated without breaking existing functionality

Pending Work

• 📋 Peer Service authentication (service not yet implemented)
