C application to decrypt game files

Hello Dmitry,

--- quote ---
The 4th parameter of CryptDeriveKey is flags, not the length of some kind.
Probably it should be CRYPT_CREATE_SALT (0x0004) if strlen("1111") works
by a pure luck :)
--- quote ---

sure ... that happens when copy/paste relay trace log snippets into a text file
and transforming into C code :)
Like: "(..., 00000004, ...) hmm, let's see ... (looks at previous call) ...
that might be the string length of passwd (skips MSDN lookup) ..." and then
things sneak in :)

Attached a new version with minor correction, thanks.

Regards
