🔐 Draft: Transform demo-plugin into comprehensive secure P2P plugin showcase

[felixboehm]

🎯 Summary

This PR transforms the demo-plugin into a comprehensive showcase of secure plugin development patterns for the TopLocs decentralized P2P platform. The changes demonstrate all security mechanisms, plugin architecture patterns, and best practices while maintaining the core P2P philosophy.

⚠️ This is a DRAFT PR - Some ideas need discussion before finalizing.

🔧 Key Changes

Plugin Architecture Cleanup

• ✅ Removed duplicated events-plugin and wiki-plugin folders from demo-plugin directory
• ✅ Removed outdated demo-frontend (had security vulnerabilities, superseded by PluginView)
• ✅ Removed unnecessary Express server for pure client-side P2P architecture
• ✅ Fixed duplicated demo-plugin/demo-plugin path structure
• ✅ Updated Module Federation configuration for multiple component slots

Comprehensive Security Implementation

• ✅ Plugin Identity & Signatures: Cryptographic plugin identity using Gun SEA
• ✅ Multi-level Encryption: Private (user), shared (group), and public (signed) data
• ✅ Permission System: Explicit user consent for plugin capabilities
• ✅ Content Addressing: IPFS-style CIDs for tamper-proof storage
• ✅ Plugin Communication: End-to-end encrypted messaging between plugins
• ✅ Entity System: Custom entities and relations integration
• ✅ Security Framework: Comprehensive validation and audit tools

🏗️ New Architecture

Component Slots System

• ./Main - Primary content area component (SecureDemo.vue)
• ./Sidebar - Sidebar widget component (PluginSidebar.vue)
• ./Settings - Plugin configuration interface (PluginSettings.vue)
• ./EntityProvider - Data provider composable (secureProvider.ts)
• ./EntityTypes - Custom entity definitions (entities.ts)

Security Mechanisms Demonstrated

// 1. Plugin Identity Generation
pluginKeys.value = await SEA.pair();

// 2. User Permission Requests  
const permission = await requestUserPermission('write', 'user-data');

// 3. Multi-level Encryption
const encrypted = await gun.user()._.sea.encrypt(data); // Private
const shared = await SEA.encrypt(data, sharedSecret);   // Group
const signed = await SEA.sign(data, pluginKeys);        // Public

// 4. Content Addressing
const cid = await gun.secure.createCID(data);

// 5. Plugin-to-Plugin Communication
await sendEncryptedMessage(targetPlugin, message);

🛡️ Security Features Demonstrated

✅ Frontend Key Generation

• Gun SEA generates cryptographically secure Ed25519 keys in browser
• Users maintain complete control over private keys
• Zero-knowledge architecture - server never sees private keys
• Aligns with decentralized philosophy

✅ Decentralized Security Mechanisms

• Digital signatures for all plugin data integrity
• User permission system with capability verification
• End-to-end encryption for sensitive data
• Group sharing with shared encryption keys
• Content-addressed storage for immutable data
• Plugin-to-plugin encrypted communication

✅ Security Best Practices

• No hardcoded secrets or keys
• No eval() or dynamic code execution
• All user data access is permission-gated
• Signatures verified on data reads
• Encryption used for sensitive operations
• Plugin-to-plugin communication secured

🤔 Discussion Points

1. Server Backend Architecture

Question: Should plugins have optional server backends for specific use cases?

Current Approach: Pure client-side P2P architecture
Alternative: Optional Gun.js relay servers for heavy computation/external APIs

2. Plugin Discovery & Distribution

Question: How should plugins be distributed and discovered in a P2P network?

Ideas for Discussion:

• IPFS-based plugin distribution
• Gun.js plugin registry with signatures
• Peer-to-peer plugin sharing
• Plugin marketplace/curation

3. Plugin Security Model

Question: Are the current security mechanisms sufficient for production use?

Current Implementation:

• Frontend key generation with Gun SEA
• Capability-based permissions
• Digital signatures for data integrity
• End-to-end encryption for privacy

Areas for Discussion:

• Plugin sandboxing mechanisms
• Cross-plugin security boundaries
• Plugin update/versioning security
• Revocation and key rotation

4. Entity System Extension

Question: How should plugins extend the core entity/relation system?

Current Approach: Custom entity types with relation definitions
Questions:

• Entity namespace collision prevention
• Cross-plugin entity compatibility
• Entity migration/versioning

🎓 Learning & Documentation

The demo plugin now serves as a comprehensive learning resource with:

• Step-by-step security implementation guide
• Interactive examples of all security mechanisms
• Best practices and security audit checklist
• Plugin development patterns and conventions
• Complete API reference and examples

🚀 Next Steps

1. Review security architecture - Validate decentralized security approach
2. Discuss plugin server patterns - Determine when/if server backends are needed
3. Test integration - Verify plugin loading in main TopLocs platform
4. Documentation review - Ensure comprehensive coverage of all patterns
5. Security audit - Professional review of cryptographic implementations
