i am using bncsutil to do the key decoding and the lockdown library that rob posted

SID_AUTH_CHECK looks like it's supplying wrong values for the file hash (string before CD-key owner name)

How are you getting your exe info string?

"starcraft.exe 16/07/08 17:45:27 1220608" is not a lockdown result, it's a ver result. Here's a good snippet to help you with using rob's lockdown dll:

[code]    If InStr(LCase$(dllName), "ix86ver") > 0 Then 'Way Old
      CRet = CheckRevisionA(HashFiles(0), HashFiles(1), HashFiles(2), CRevRequest, EXEVersion, Checksum, CRevResult, dllName)
    ElseIf InStr(LCase$(dllName), "ver-ix86") > 0 Then 'D2/W3
      CRet = CheckRevisionB(HashFiles(0), HashFiles(1), HashFiles(2), CRevRequest, EXEVersion, Checksum, CRevResult, dllName)
    Else 'Lockdown
      CRet = CheckRevisionEx(HashFiles(0), HashFiles(1), HashFiles(2), CRevRequest, EXEVersion, Checksum, CRevResult, SettingsFolder & "\Tmp\MPQs\" & dllName, vbNullString, HashFiles(3))
    End If[/code]

i just hardcoded the exe info into that packet...

andi, i am using only the third of your possibilities:
[code]
if(!CheckRevision(fnames[0], fnames[1], fnames[2], valuestring, &version, &checksum, digest, ix86verfname, fnames[3]))
[/code]

fnames[0] is "Starcraft.exe"
fnames[1] is "storm.dll"
fnames[2] is "battle.snp"
valuestring is a 16 byte hex value (from the 0x50 packet)
version is the variable that will hold the version that checkrevision gives me
checksum is the variable that will hold the checksum that checkrevision gives me
digest
ix86verfname is "lockdown-IX86-xx.dll" (from the 0x50 packet)
fnames[3] is "STAR.bin" (screendump)

Well, that exe info string should be the "digest".

ah, i didnt know that. this is what i have now, i insert the digest instead of my selfmade string:

i still need the cdkey owner "chin.fu", right?

ah i got it, my last mistake was a wrong exeVersion value.

pkt_insertdword(&tcppacket, 0x0f010102); // exeVersion


do i have to sniff this value for each patch? like the version byte?

ExeVersion is already extracted in your code as "&version".

ah! of course, thanks
