This middleware implements HTTP Digest Authentication according to RFC 7616, providing a more secure alternative to Basic Authentication. It supports all standard hash algorithms including MD5, SHA, SHA-256, SHA-512 and their session variants, as well as both 'auth' and 'auth-int' quality of protection (qop) options.

This middleware intercepts 401 Unauthorized responses containing a Digest authentication challenge, calculates the appropriate digest credentials, and automatically retries the request with the proper Authorization header. Features: - Handles all aspects of Digest authentication handshake automatically - Supports all standard hash algorithms: - MD5, MD5-SESS - SHA, SHA-SESS - SHA256, SHA256-SESS, SHA-256, SHA-256-SESS - SHA512, SHA512-SESS, SHA-512, SHA-512-SESS - Supports 'auth' and 'auth-int' quality of protection modes - Properly handles quoted strings and parameter parsing - Includes replay attack protection with client nonce count tracking - Supports preemptive authentication per RFC 7616 Section 3.6 Standards compliance: - RFC 7616: HTTP Digest Access Authentication (primary reference) - RFC 2617: HTTP Authentication (deprecated by RFC 7616) - RFC 1945: Section 11.1 (username restrictions) Implementation notes: The core digest calculation is inspired by the implementation in https://github.com/requests/requests/blob/v2.18.4/requests/auth.py with added support for modern digest auth features and error handling.
