what are you talking about? I made it 9 months ago and released just now.
if there is another version of this library for SQL Server x64 - show it me.

[pquintal]

I search for this on net one month ago, no results, this not exist in another place, only exist for x86 systems

Well, maybe it exists, but is not public...

[wolfulus]

the one that I have matches original x86 results too. this one seems to be fk up.. be careful migrating your server to SQL Server x64 using this dll.

[xakumm]

navossoc, wolfulus,
you should use only varchar (or char), because the use unicode is a big mistake and unsafe - for password guessing need only the first character ( check it: )

DECLARE @btInStr0 NVARCHAR(10), @btInStr1 NVARCHAR(10), @btInStr2 NVARCHAR(10)
DECLARE @btInStrIndex	NVARCHAR(10)
DECLARE	@btOutVal	BINARY(16)
set @btInStr0 = N'password'
set @btInStr1 = N'pass'
set @btInStr2 = N'p'
set @btInStrIndex = N'login'
EXEC master..XP_MD5_EncodeKeyVal @btInStr0, @btInStrIndex, @btOutVal OUT
print @btOutVal
EXEC master..XP_MD5_EncodeKeyVal @btInStr1, @btInStrIndex, @btOutVal OUT
print @btOutVal
EXEC master..XP_MD5_EncodeKeyVal @btInStr2, @btInStrIndex, @btOutVal OUT
print @btOutVal

/* result: 
	0x124C67DED6D675FE458137B70BBDC41E
	0x124C67DED6D675FE458137B70BBDC41E
	0x124C67DED6D675FE458137B70BBDC41E */

I changed the library (download from first post), what would the outcome was in the original library x86, but my dll already correctly worked with varchar.

TBH, i really don't care about it or even use it...

It just don't mimic the original behavior, so it's broken in my opinion, but now seems you have fixed it...

If are you using a sql server 32 bits, why want you use this DLL?
Just use the original one...
