Unlike OAuth 1, this HMAC signature does not require inclusion of the request payload/body, neither does it use a combination of client_secret and token_secret but rather a mac_key provided together with the access token. Currently two algorithms are supported, "hmac-sha-1" and "hmac-sha-256", `extension algorithms`_ are not supported. Example MAC Authorization header, linebreaks added for clarity Authorization: MAC id="h480djs93hd8", nonce="1336363200:dj83hs9s", mac="bhCQXTVyfj5cmA9uKkPFx1zeOXM=" .. _`MAC Access Authentication`: https://tools.ietf.org/html/draft-ietf-oauth-v2-http-mac-01 .. _`extension algorithms`: https://tools.ietf.org/html/draft-ietf-oauth-v2-http-mac-01#section-7.1 :param token: :param uri: Request URI. :param key: MAC given provided by token endpoint. :param http_method: HTTP Request method. :param nonce: :param headers: Request headers as a dictionary. :param body: :param ext: :param hash_algorithm: HMAC algorithm provided by token endpoint. :param issue_time: Time when the MAC credentials were issued (datetime). :param draft: MAC authentication specification version. :return: headers dictionary with the authorization field added. r- z hmac-sha-256zunknown hash algorithmr z{}:{}�?Nzutf-8���r, � z MAC id="%s"zts="%s"z nonce="%s"z bodyhash="%s"zext="%s"zmac="%s"z, � Authorization)�upperr � host_from_uri�lower�hashlib�sha1�sha256� ValueError�format� generate_ager �generate_nonce�generate_timestampr �encoder �digest�decode�append�join� isinstance�str�hmac�new)�token�uri�key� http_method�nonce�headers�body�ext�hash_algorithm� issue_time�draft�host�port�h�ts�sch�net�path�par�query�fra� request_uri�bodyhash�base� base_string�sign�headerr r r �prepare_mac_headerC sf ( � ra c C � t |d| fg�S )a Add a `Bearer Token`_ to the request URI.
