Function name : CreateMD5SSOHash

Group: Internet Functions (WinInet) - Library: wininet

---

Obtains the default Microsoft Passport password for a specified account or realm, creates an MD5 hash from it using a specified wide-character challenge string, and returns the result as a string of hexadecimal digit bytes.

---

Declaration:

BOOL CreateMD5SSOHash(
	PWSTR pszChallengeInfo,
	PWSTR pwszRealm,
	PWSTR pwszTarget,
	PBYTE pbHexHash
);  

---

FoxPro declaration:

DECLARE INTEGER CreateMD5SSOHash IN wininet;
	STRING pszChallengeInfo,;
	STRING pwszRealm,;
	STRING pwszTarget,;
	STRING @pbHexHash  

---

Parameters:

pszChallengeInfo [in] Pointer to wide-character challenge string.

pwszRealm [in] Pointer to a string that names a realm for which to obtain the password. This parameter is ignored unless pwszTarget is NULL. If both pwszTarget and pwszRealm are NULL, the default realm is used. pwszTarget

[in] Pointer to a string that names an account for which to obtain the password. If pwszTarget is NULL, the realm indicated by pwszRealm is used. pbHexHash

[out] Pointer to an output buffer into which the MD5 hash is returned in hex string format. This buffer must be at least 33 bytes long.

---

Return value:

Returns TRUE if successful, or FALSE otherwise.

---

Comments:

There is no need to call the InternetOpen before calling the CreateMD5SSOHash.

The usage is as simple as it can be:

cSource=STRCONV("challenge"+CHR(0),5) cRealm=NULL cTarget=NULL && "[email protected]" cHash = REPLICATE(CHR(0), 33)

? CreateMD5SSOHash(cSource, cRealm, cTarget, @cHash)
cHash = STRTRAN(cHash, CHR(0))
? LEN(cHash), "[" + cHash + "]"

For this code to return a valid result, a .Net Passport (Microsoft Passport) must be installed on the Windows XP computer.
