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

Parameters	serv_type	An indication of what kind of server authentication is being attempted against. For example, `u"xmpp"`. (type: `unicode`)

Returns initial client response string. (type: str.)

def getResponse(self, challenge): (source)

Get the response to a server challenge.

Parameters	challenge	server challenge. (type: `str`.)
Returns	client response. (type: `str`.)

def _parse(self, challenge): (source)

Returns challenge directives and their values. (type: dict of str to str.)

def _unparse(self, directives): (source)

Create message string from directives.

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

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

Calculates response with given encoded parameters.

Returns The response field of a response to a Digest-MD5 challenge of the given parameters. (type: bytes)
