Description

Motivation The project implements custom HTTP digital-signature logic in digital_signatures.py (canonicalization, signature headers, content digests). This is security-sensitive and unnecessary to maintain in-house.

Goal Refactor digital_signatures.py to use an RFC 9421-compliant HTTP message-signature library, while keeping eBay-specific signing requirements unchanged.

Recommended Technology requests-http-signature https://github.com/pyauth/requests-http-signature

Outcome Improved correctness, reduced security risk, and less non-core maintenance.

Contributor guide

Research direction
Inspect digital signatures.py to understand the current custom signing logic, then study RFC 9421 and the requests http signature library to replace the implementation while preserving eBay specific requirements.
