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 function handles the complex format of WWW-Authenticate header values, supporting both quoted and unquoted values, proper handling of commas in quoted values, and whitespace variations per RFC 7616. Examples of supported formats: - key1="value1", key2=value2 - key1 = "value1" , key2="value, with, commas" - key1=value1,key2="value2" - realm="example.com", nonce="12345", qop="auth" Args: header: The header value string to parse Returns: Dictionary mapping parameter names to their values )_HEADER_PAIRS_PATTERNfindallstripr>)r?key quoted_val unquoted_val stripped_keys r$parse_header_pairsrHsZ,.C-J-J6-R   )C\IIK 'L ' Zoj1\Q  s-A c eZdZdZ ddedededdfdZded ed ee e d fdefd Z d edefd Z de defdZdedede fdZy)DigestAuthMiddlewarea HTTP digest authentication middleware for aiohttp client. This middleware intercepts 401 Unauthorized responses containing a Digest authentication challenge, calculates the appropriate digest credentials, and automatically retries the request with the proper Authorization header. Features: - Handles all aspects of Digest authentication handshake automatically - Supports all standard hash algorithms: - MD5, MD5-SESS - SHA, SHA-SESS - SHA256, SHA256-SESS, SHA-256, SHA-256-SESS - SHA512, SHA512-SESS, SHA-512, SHA-512-SESS - Supports 'auth' and 'auth-int' quality of protection modes - Properly handles quoted strings and parameter parsing - Includes replay attack protection with client nonce count tracking - Supports preemptive authentication per RFC 7616 Section 3.6 Standards compliance: - RFC 7616: HTTP Digest Access Authentication (primary reference) - RFC 2617: HTTP Authentication (deprecated by RFC 7616) - RFC 1945: Section 11.1 (username restrictions) Implementation notes: The core digest calculation is inspired by the implementation in https://github.com/requests/requests/blob/v2.18.4/requests/auth.py with added support for modern digest auth features and error handling. loginpassword preemptiver5Nc| td| tdd|vr td||_|jd|_|jd|_d|_d|_i|_||_g|_ y)Nz"None is not allowed as login valuez%None is not allowed as password value:z8A ":" is not allowed in username (RFC 1945#section-11.1)utf-8r#r) ValueError _login_strencode _login_bytes_password_bytes_last_nonce_bytes _nonce_count _challenge _preemptive_protection_space)selfrKrLrMs r$__init__zDigestAuthMiddleware.__init__s =AB B  DE E %<WX X&+*/,,w*?-5__W-E!$/1!+,.r#methodurlbodyr#c #$K|j}d|vr tdd|vr td|d}|d}|s td|jdd}|jdd }|j} |jd d} |j d } |j d } t |j } d}d }|rxd dhj|jdDchc]#}|js|j%c}}|std|d|vrdnd }|j d }| tvr$td| ddjtt| $dtdtf$fd #dtdtdtf#fd }dj|j| |jf}|jd| j }|dk(rFt!|t"r|j%d{}n|}#|}dj||f}#|}#|}| |j&k(r|xj(dz c_nd|_| |_|j(d}|j d }t+j,d jt/|j(j d | t1j2j d t5j6dgj9dd }|j d }| jj;d!r#dj|| |f}|r dj| ||||f}|||}n||dj| |f}t=|j>t=|t=|| |jA|d"}| rt=| |d <|r||d<||d#<||d$<g} |jCD];\}!}"|!tDvr| jG|!d%|"d&&| jG|!d'|"=d(dj| Scc}w7`w))a Build digest authorization header for the current challenge.
