Kindle for PC is there

[wallflower75]

I'm a little confused. So in order to be able to strip DRM from a Kindle file right now, I'd have to download the file to either a Kindle or an iPhone/iPod touch in order to use the device's PID. Do I have that right?

Yes, which is probably why there is such strong interest in finding the PID for a registered "Kindle for PC" install. (I know that this is the only reason currently I'm interested in Kindle for PC, despite having an iPhone)

Actually K4PC offers one advantage and that is to figure out which book to pull off the ipod touch/iphone. The naming convention is the same, so you can open the book you want in k4pc, turn a few pages, go to the kindple4pc dir and do a sort by date. The latest .mbp file is the name of the ebook you want to get off the touch. Ive struggled with that issue somewhat in the past

what about sorting by date and keeping track when you bought them? that works for me easily

Actually good point...Before when I was using bonjour I dont remember being able to sort by date, but now that I am just doing it via SSH, that works fine.

Or you can just look up the book on Amazon. The filename used for kindle books is the ASIN number listed in the product details (and also in the link for the book).

Actually you don't have to DL to the Kindle, you just have to DL the varient that was made for the Kindle. If you own a Kindle you can DL to your computer and transfer to your Kindle. This is different from DLing to your Kindle4PC which has it's own unique name.

And yes, this had already been established (and, as a matter of logic, should not be surprising.)

The fact is, every entity registered into the Kindle system, the listing you can see when you go to the site to "Manage Kindle," represents a unique encryption target and, assuming they all use the same type of encryption (no special reason this would be required, even within the mobi basic file format,) they'll all have unique PIDs too.

The only thing close to an overlap is the direct download link from your "owned" books listing which is intended for manually loading books onto a Kindle/Kindle 2 and I would imagine that if you had multiple standard Kindles on your account that link would be duplicated for each one.

Based on a single AZW book DLed to two different Kindle4PCs and run through a compare (by byte) there were 177 bytes that were different. I assume that the Kindle4PC's PID is embedded in there somewhere but I doubt that it is not encrypted in some manner.

Do you have a diff of those two files?

That's beside the point. ADE restrictions become an issue when you have multiple computers/devices on the same account. I can no longer use my work computer for ADE because of a known issue (it kept on re-registering with ADE each time I started the program) and I can no longer add new computers (I tried and failed to add my daughter's new netbook). Amazingly, I was able to add my Pocketbook 360 BEFORE I had installed the experimental firmware which support DRM epub and PDF. That was an odd, but welcome and encouraging, occurrence. However, I am still dreading what will happen when I have another hard-drive failure or wish to upgrade my OS on my ASUS. It is not clear to me that ADE will recognize my computer as a re-registration of a previously recognized one. De-Registering the computer (if possible) apparently does not get your activation count lowered, like it does with Sony. Right now, with my Pocketbook 360, ADE is working. It does not work well for my Sony in regards to library books. There is no guarantee it will work well when I upgrade my computer, which may not be too far in the future. I have no such fear in regard to EReader. I hope that Pocketbook will upgrade their support of adobe DRM to include the social DRM which is being licensed from B and N. I would gladly support B and N if they make it easy for me to get reasonably priced content onto my reader, with no worries about problems caused by hardware failure.

I do concede your points in regards to the technical limitations of eReader, although I have still come across eReader books that look nice. I have my own gripe against the format: the html coding works fine on windows but often does not work well on linux because the coders got careless and referenced image file names in the wrong case (windows is not case-sensitive, linux is). As a result, I have had to manually rename the image files I get when I explode an eReader file with the python script. I don't think this is the script's fault; the names of images appear to be those given by the publisher and the html seems to be the publisher's source.

The PID is in the book, but encoded with the PID itself, if I'm reading the MobiDeDRM code right. You can take the PID, and check that a book is encoded using that PID, but you can't get the PID back from the book.

What you need to do is find where Kindle4PC is storing the PID it uses. I suppose it must send this PID back to Amazon at some point, so perhaps a packet sniffer could spot this. I'd be surprised if they weren't encoding it though.

Kindle4PC must store the PID it's using somewhere on the PC's hard disk. But finding it and decoding it is more than I can manage.

Oh wow, so it is...and ive had to figure it out the hard way for so long This gets tip of the day status. Excellent first post!

Did you call or email Adobe support? They can remove the extraneous devices registered to your account.

Or, equally likely, in the Windows Registry. That bracketed string looks to me like a CLSID. Depends, somewhat, on how 'universal' they wrote the app. Sure, right now it's only for Windows (or Windows emulators-same thing) but if they really thought it thru they'd probably store it on the HD so the storage/retrieval subsystem could work on all OS's.

I've searched through the registry. Nothing vital is stored there.

I could recreate the output that would include the hex addresses if necessary.
