t.c._digest : module documentation

Calculations for HTTP Digest authentication.

See Also http://www.faqs.org/rfcs/rfc2617.html

Function	calcHA1	Compute H(A1) from RFC 2617.
Function	calcHA2	Compute H(A2) from RFC 2617.
Function	calcResponse	Compute the digest for the given parameters.

def calcHA1(pszAlg, pszUserName, pszRealm, pszPassword, pszNonce, pszCNonce, preHA1=None): (source)

Compute H(A1) from RFC 2617.

Parameters	pszAlg	The name of the algorithm to use to calculate the digest. Currently supported are md5, md5-sess, and sha.
	pszUserName	The username
	pszRealm	The realm
	pszPassword	The password
	pszNonce	The nonce
	pszCNonce	The cnonce
	preHA1	If available this is a str containing a previously calculated H(A1) as a hex string. If this is given then the values for pszUserName, pszRealm, and pszPassword must be `None` and are ignored.

def calcHA2(algo, pszMethod, pszDigestUri, pszQop, pszHEntity): (source)

Compute H(A2) from RFC 2617.

Parameters	pszAlg	The name of the algorithm to use to calculate the digest. Currently supported are md5, md5-sess, and sha.
	pszMethod	The request method.
	pszDigestUri	The request URI.
	pszQop	The Quality-of-Protection value.
	pszHEntity	The hash of the entity body or `None` if `pszQop` is not `'auth-int'`.
Returns	The hash of the A2 value for the calculation of the response digest.

def calcResponse(HA1, HA2, algo, pszNonce, pszNonceCount, pszCNonce, pszQop): (source)

Compute the digest for the given parameters.

Parameters	HA1	The H(A1) value, as computed by `calcHA1`.
	HA2	The H(A2) value, as computed by `calcHA2`.
	pszNonce	The challenge nonce.
	pszNonceCount	The (client) nonce count value for this response.
	pszCNonce	The client nonce.
	pszQop	The Quality-of-Protection value.
