In my testing I have found that Windows always fills a header buffer,
a data buffer and then a trailer buffer in DecryptMessage. It optionally
returns another data buffer when there's more data to be decrypted
than the supplied buffer can hold.

Wine currently does not do any of that, which might explain what you're
seeing.
