March 2026 monthly summary for google/quiche: Delivered Privacy-Enhanced Access Token (PAT) generation at prober request time, with enhanced RSA key parsing from files and in-memory data to support secure token generation. Issuer private key retrieved from keystore; public key loaded on gateways and prober-origin tagging ensures correct PAT attribution. This change improves security, reduces token issuance latency, and strengthens key management. No major bugs fixed this month; minor maintenance and alignment with security policy completed.

January 2026 (Month 2026-01) — Focused on delivering robust Oblivious HTTP support and reliable Binary HTTP decoding in google/quiche, with expanded test coverage to validate end-to-end workflows and OSS compatibility. The work delivers security, reliability, and maintainability gains while enabling scalable adoption of Oblivious HTTP. What was delivered: - Oblivious HTTP error handling and protocol compliance: wrap user chunk handler errors in InternalError and enforce non-final zero-length chunks as decryption errors per the latest OHTTP draft. (Commits: 7d647e9170182ed718948dd8ce3a6f8de379b571; 609c6f073f698c4642ffe48854b0842e9829f901) - BHTTP Indeterminate Length Decoding improvements: refactor to use a local checkpoint, simplify state handling, memory management improvements, and updated decoder/constructor patterns to pass retained parameters as pointers. (Commits: bbbd816f77ee9d47c30388d0be23f2d2b746372a; 0b2dacac0ab0e36e9e6699a4e2043074988e56cb; 0d44d14e058226e40c5b80f331af8c58edc9fcb6; e70153a2431704d7a1dfe8395c44673c5a9a4407; 574c4f9a4b49b31f9599054252b860325cb7570f; 3d2c5637b20af7f06acb6aa7d11062cc13996cf6; 0cb8481fbfc019bcc02aada7e700930f28128c7f) - Test infrastructure and integration tests for Oblivious HTTP: added end-to-end integration tests, refactored test helpers to return statuses, and improved HttpHeaderBlock tests for OSS Envoy compatibility. (Commits: e95839a15fc1b8e2bab5ddb35c055f7965dd7ec2; c52d86fe10442363e4e8c5a66e639187c419d7c0; 123dbc68a94f0ab19d1f8b63e1812abbbb1c17a7) Overall impact and accomplishments: - Strengthened security and protocol compliance for Oblivious HTTP, reducing misclassification of errors and aligning with current drafts. - Increased decoding reliability and maintainability for BHTTP indeterminate-length messages, laying groundwork for robust real-time streaming and informational responses. - Expanded test coverage and OSS compatibility, reducing QA cycles and enabling safer rollout in production environments. Technologies/skills demonstrated: - C++, Abseil (absl::string_view, Span), pointer-based API design, memory management - Oblivious HTTP and BHTTP protocol concepts and RFC considerations - End-to-end integration testing, test scaffolding, and OSS Envoy compatibility - Refactoring for readability, correctness, and performance

December 2025 monthly summary focusing on key accomplishments for google/quiche. Delivered the Chunked Oblivious HTTP Client feature enabling streaming encryption of OHTTP requests and decryption of OHTTP responses in chunks, aligning with the chunked Oblivious HTTP draft and enabling incremental processing for more secure and efficient HTTP communications. The work establishes a streaming OHTTP path and sets the foundation for production-ready chunked processing, with reference metadata captured in commit messages.

Concise monthly performance summary for 2025-11 focused on google/quiche contributions. Highlights include delivering an indeterminate-length Binary HTTP request encoder and refactoring the decoder for modularity and future encoder integration, refactoring OHTTP buffers to enable a chunked client with API surface exposure for encryption/decryption, and fixing decryption error messaging to include nonce for clarity. The work emphasizes test reuse, clearer APIs, and prepare-for-extension architecture to support future protocol features and performance improvements.

October 2025 monthly summary for google/quiche. Focused on improving observability for Masque OHTTP client by adding status code logging for decoded OHTTP responses, enabling faster debugging and incident response. This month delivered a focused feature with clear business value and low risk.

Monthly summary for 2024-11 focused on dependency upgrade and build hygiene for envoyproxy/envoy. Implemented a QUICHE upgrade to a newer version and streamlined the build by removing unused library targets. Updated QUICHE version/SHA256 hash in the build configuration to ensure integrity and reproducibility.
