Method	`__init__`
Method	`getInitialResponse`	Get the initial client response, if defined for this mechanism.
Method	`getResponse`	Get the response to a server challenge.
Class Variable	`name`	Common name for the SASL Mechanism.
Instance Variable	`defaultRealm`	Undocumented
Instance Variable	`digest_uri`	Undocumented
Instance Variable	`password`	Undocumented
Instance Variable	`username`	Undocumented
Method	`_calculateResponse`	Calculates response with given encoded parameters.
Method	`_gen_nonce`	Undocumented
Method	`_genResponse`	Generate response-value.
Method	`_parse`	Parses the server challenge.
Method	`_unparse`	Create message string from directives.

def __init__(self, serv_type, host, serv_name, username, password): (source)

Parameters
serv_type:`unicode`	An indication of what kind of server authentication is being attempted against. For example, `u"xmpp"`.
host:`unicode`	The authentication hostname. Also known as the realm. This is used as a scope to help select the right credentials.
serv_name:`unicode`	An additional identifier for the server.
username:`unicode`	The authentication username to use to respond to a challenge.
password:`unicode`	The authentication password to use to respond to a challenge.

def _calculateResponse(self, cnonce, nc, nonce, username, password, realm, uri): (source)

Calculates response with given encoded parameters.

Returns
`bytes`	The response field of a response to a Digest-MD5 challenge of the given parameters.

def _gen_nonce(self): (source)

Undocumented

def _genResponse(self, charset, realm, nonce): (source)

Generate response-value.

Creates a response to a challenge according to section 2.1.2.1 of RFC 2831 using the charset, realm and nonce directives from the challenge.

def _parse(self, challenge): (source)

Parses the server challenge.

Splits the challenge into a dictionary of directives with values.

Returns
`dict` of `str` to `str`.	challenge directives and their values.

def _unparse(self, directives): (source)

Create message string from directives.

Parameters
directives:`dict` of `str` to `str`	dictionary of directives (names to their values). For certain directives, extra quotes are added, as needed.
Returns
`str`.	message string.
