From 543ab216f975b004e632bf76d20d3a9419ead0a8 Mon Sep 17 00:00:00 2001 From: anthonyrawlins Date: Tue, 2 Sep 2025 20:02:37 +1000 Subject: [PATCH] Complete BZZZ functionality port to CHORUS MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 🎭 CHORUS now contains full BZZZ functionality adapted for containers Core systems ported: - P2P networking (libp2p with DHT and PubSub) - Task coordination (COOEE protocol) - HMMM collaborative reasoning - SHHH encryption and security - SLURP admin election system - UCXL content addressing - UCXI server integration - Hypercore logging system - Health monitoring and graceful shutdown - License validation with KACHING Container adaptations: - Environment variable configuration (no YAML files) - Container-optimized logging to stdout/stderr - Auto-generated agent IDs for container deployments - Docker-first architecture All proven BZZZ P2P protocols, AI integration, and collaboration features are now available in containerized form. Next: Build and test container deployment. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- api/http_server.go | 243 ++ api/setup_manager.go | 2476 +++++++++++++++++

security for contextual intelligence with comprehensive features including multi-layer encryption, sophisticated access controls, automated key management, and extensive compliance monitoring. The system is designed to scale to enterprise requirements while maintaining the highest security standards and providing complete audit transparency. + +For additional information, support, or contributions, please refer to the project documentation or contact the security team. + +--- + +**Security Notice**: This system handles sensitive contextual information. Always follow security best practices, keep systems updated, and conduct regular security assessments. Report any security issues immediately to the security team. + +**Compliance Notice**: This system is designed to meet multiple compliance standards. Ensure proper configuration and monitoring for your specific compliance requirements. Regular compliance audits are recommended. + +**Performance Notice**: While the system is optimized for performance, encryption and access control operations have computational overhead. Plan capacity accordingly and monitor performance metrics in production environments. \ No newline at end of file diff --git a/pkg/crypto/age_crypto.go b/pkg/crypto/age_crypto.go new file mode 100644 index 0000000..738073c --- /dev/null +++ b/pkg/crypto/age_crypto.go @@ -0,0 +1,492 @@ +// Package crypto provides Age encryption implementation for role-based content security in BZZZ. +// +// This package implements the cryptographic foundation for BZZZ Phase 2B, enabling: +// - Role-based content encryption using Age (https://age-encryption.org) +// - Hierarchical access control based on agent authority levels +// - Multi-recipient encryption for shared content +// - Secure key management and validation +// +// The Age encryption system ensures that UCXL content is encrypted before storage +// in the distributed DHT, with access control enforced through role-based key distribution. +// +// Architecture Overview: +// - Each role has an Age key pair (public/private) +// - Content is encrypted for specific roles based on creator's authority +// - Higher authority roles can decrypt lower authority content +// - Admin roles can decrypt all content in the system +// +// Security Model: +// - X25519 elliptic curve cryptography (Age standard) +// - Per-role key pairs for access segmentation +// - Authority hierarchy prevents privilege escalation +// - Shamir secret sharing for admin key distribution (see shamir.go) +// +// Cross-references: +// - pkg/config/roles.go: Role definitions and authority levels +// - pkg/dht/encrypted_storage.go: Encrypted DHT storage implementation +// - pkg/ucxl/decision_publisher.go: Decision publishing with encryption +// - docs/ARCHITECTURE.md: Complete system architecture +// - docs/SECURITY.md: Security model and threat analysis +package crypto + +import ( + "bytes" + "fmt" + "io" + "strings" + + "filippo.io/age" // Modern, secure encryption library + "chorus.services/bzzz/pkg/config" +) + +// AgeCrypto handles Age encryption for role-based content security. +// +// This is the primary interface for encrypting and decrypting UCXL content +// based on BZZZ role hierarchies.
