Description: The first one had intended to the commercial document transparent encryption driver code class the minifilter. Remember normal word plus decryption key is completely divorced from the complex MS (personally think) minifilter source. Is definitely not used to commercial, with estimated have to be changed to change, but at least the logic is very clear, I feel very good if used entry, of course, a complete turn over minifilter do not need to read. As for the brush cache and multi-cache, this is a matter of opinion. I think both implement this level of commercial, is that you can. As a veteran in the read operation DMK and a professional manufacturer of pure brush cache products, personal think it is unnecessary tangle only need to focus on the good product on line, how to achieve, no need contests . After all, minifilter the the official standard MS layerfsd, and it took the long-term verification of OSR, both of which are desirable.
