Digest Authentication Header Generator

Indigestion is a focused Node.js library designed to generate HTTP Digest Authentication strings. It specifically takes the `WWW-Authenticate` header from a 401 response and provides the `Authorization` header content. The current stable version is v0.4.0, with releases appearing to be on-demand for maintenance or minor feature additions rather than a strict schedule, as indicated by the most recent release in February 2026. This library differentiates itself from other digest authentication solutions (like `axios-digest` or `node-digest-auth-client`) by offering only the header generation functionality, allowing developers full control over the HTTP request client and lifecycle. It aims to fill a niche where only the calculated `Digest` header string is needed, without the library dictating how the actual HTTP request is made.
