[Flightgear-devel] OT: decryption
OK, so I ordered some flight manuals on CD from eflightmanuals.com, but what they didn't tell me is that they send them in a proprietary encryption scheme for PDF files that requires Windows ME of later which I don't have. According to the encryption software manufacturers it is AES 256 bit (FIPS-197) Now, I have the key of course, the question is how would I go about decrypting it in the absense of the proprietary software? Oh, There is also a second key for the software, probably tied to the specific machine it will be run on, I think I can sniff this with snort. I would not recommend patronizing these guys, they have been very slow and unhelpful. In addiditon I'm not even sure if there policies reguarding no returns and their failure to accurately describe the restrictions on the produce are even legal. I am currently looking into that as well.

I tried running it under wine, but it complained that I was not running the correct version of windows. I suspect that it failed to find some DRM system. So far this software is the *only* way I have of decrypting the file, and once it does it is very picky about what it does with the data. All I can do is borrow a windows box and take screenshots from an external program. According to Locklizard, this stuff is stored encrypted in memory and decrypted on the fly too, so I won't be able to grab it out of RAM. I have to say, Locklizard seems to know what they are doing.

For an old POH I would just go to the National Archives in College Park, which is about half an hour away. Problem is, the version of the Canberra that I'm interested in was never flown by the USAF. Besides, dealing with the archives isn't exactly painless either. Really, the least painful option would be to put in a few extra hours at work and then order a hard copy from the same guys (actually, someone else has a hardcopy for sale that is even closer to what I want, British instead of Australian). I'm pretty sure I would be happy with that service. I'm just perennially annoyed by DRM. If I had know I would have bought paper.

The F-51D handbook I ordered a year or so ago is a plain encrypted PDF (with an extra step to get it off the CD that involves an emailed key). It printed just fine from acrobat reader; I have the hardcopy still to prove it. This is upsetting. It makes the manuals more or less useless to those of us who don't use windows as our desktop OS. Ah well. I retract the nice things I said about eflightmanuals.com.

Re: [Flightgear-devel] OT: decryption
Josh, I have bought 4-5 manuals from them, and I have seen 2 types of copy protection, both a pain in the rear. I have also found them to be a little slow in the response category, so I agree on that point also. On the return front, no returns for media is up to the seller, especially in the case of media that can be copied easily.But if you can't use the product because of the copy scheme...I would think they would be required to honor a refund. You can always reverse the CC charge with the CC company But, they do have a great selection of manuals, for a low price...and I don't have to fool around with Ebay. If you know of another comprehensive source that is about the same price...I would love to check them out.
