An implementation of the server-side of HTTP Digest Access Authentication, which is described in :rfc:`2617`.
Example usage, using the built-in get_ha1_dict_plain function which uses a dict of plaintext passwords as the credentials store:
userpassdict = {'alice' : '4x5istwelve'} get_ha1 = cherrypy.lib.auth_digest.get_ha1_dict_plain(userpassdict) digest_auth = {'tools.auth_digest.on': True, 'tools.auth_digest.realm': 'wonderland', 'tools.auth_digest.get_ha1': get_ha1, 'tools.auth_digest.key': 'a565c27146791cfb', } app_config = { '/' : digest_auth }

Returns a get_ha1 function which obtains a plaintext password from a dictionary of the form: {username : password}. If you want a simple dictionary-based authentication scheme, with plaintext passwords, use get_ha1_dict_plain(my_userpass_dict) as the value for the get_ha1 argument to digest_auth(). |
Returns a get_ha1 function which obtains a HA1 password hash from a dictionary of the form: {username : HA1}. If you want a dictionary-based authentication scheme, but with pre-computed HA1 hashes instead of plain-text passwords, use get_ha1_dict(my_userha1_dict) as the value for the get_ha1 argument to digest_auth(). |
Returns a get_ha1 function which obtains a HA1 password hash from a flat file with lines of the same format as that produced by the Apache htdigest utility. For example, for realm 'wonderland', username 'alice', and password '4x5istwelve', the htdigest line would be: alice:wonderland:3238cdfe91a8b2ed8e39646921a02d4c If you want to use an Apache htdigest file as the credentials store, then use get_ha1_file_htdigest(my_htdigest_file) as the value for the get_ha1 argument to digest_auth(). It is recommended that the filename argument be an absolute path, to avoid problems. |
Synthesize a nonce value which resists spoofing and can be checked for staleness. Returns a string suitable as the value for 'nonce' in the www-authenticate header. s A string related to the resource, such as the hostname of the server. key A secret string known only to the server. timestamp An integer seconds-since-the-epoch timestamp |
A CherryPy tool which hooks at before_handler to perform HTTP Digest Access Authentication, as specified in :rfc:`2617`. If the request has an 'authorization' header with a 'Digest' scheme, this tool authenticates the credentials supplied in that header. If the request has no 'authorization' header, or if it does but the scheme is not "Digest", or if authentication fails, the tool sends a 401 response with a 'WWW-Authenticate' Digest header. realm A string containing the authentication realm. get_ha1 A callable which looks up a username in a credentials store and returns the HA1 string, which is defined in the RFC to be MD5(username : realm : password). The function's signature is: ``get_ha1(realm, username)`` where username is obtained from the request's 'authorization' header. If username is not found in the credentials store, get_ha1() returns None. key A secret string known only to the server, used in the synthesis of nonces. |
