From a6cb158e6ba760030553c129f497354a96c09f40 Mon Sep 17 00:00:00 2001 From: Andre Ferreira Date: Wed, 10 Dec 2025 03:51:21 -0300 Subject: [PATCH 01/18] feat: add ECC-AES payload encryption support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements end-to-end encryption for vector payloads using: - ECC (P-256) for key exchange via ECDH - AES-256-GCM for symmetric encryption - Zero-knowledge architecture (server cannot decrypt) Changes: - Added payload_encryption module with encrypt_payload function - Updated Payload model with encryption detection methods - Added EncryptionConfig to CollectionConfig - Added encryption validation in Collection::insert_batch - Support for hex, PEM, and base64 public key formats - Added EncryptionRequired and EncryptionError types - Fixed all CollectionConfig initializations across codebase Dependencies: - p256 v0.13 for ECC operations - hex v0.4 for hexadecimal encoding πŸ€–

charset=UTF-8 Content-Transfer-Encoding: 8bit Completes the payload encryption feature with GraphQL support, full SDK coverage, comprehensive testing, and organized documentation. Key additions: - GraphQL encryption: Added publicKey parameter to upsertVector, upsertVectors, updatePayload, and uploadFile mutations - Complete SDK support: Updated all 6 official SDKs (TypeScript, JavaScript, Python, Go, C#, Rust) with encryption support and examples - Comprehensive testing: 32 total tests (26 REST + 6 GraphQL), 100% route coverage - Documentation: Organized all encryption docs in docs/features/encryption/ with English translations - Version bump: Server and all SDKs updated from 2.0.x to 2.1.0 Technical implementation: - GraphQL uses camelCase publicKey field with proper #[graphql(name = "publicKey")] attributes - Per-vector encryption override supported in batch operations - Consistent API across REST, GraphQL, MCP, and Qdrant-compatible endpoints - Zero-knowledge architecture maintained throughout Documentation: - Updated OpenAPI spec to v2.1.0 with encryption parameters - Added comprehensive encryption section to docs/api/README.md - Centralized encryption docs in docs/features/encryption/README.md -
