Python is extremely picky about the amount lines are indented. You need to add or remove spaces at the start of the line complained about to make it match the other lines. (Not necessarily the same indent as the line before it though - Python uses indents to mark sections like C uses {}, so the conditionally executed statements of an if statement need to be one 'indent amount' in. Usually four space multiples in my experience.

It's a policy at Mobileread that direct links aren't posted to DRM removal tools. A moderator should edit your post shortly, or you could edit it yourself.

You need to read up on indentation in Python.

Would love to be able to use this (if I had it), since I have about 90 PDF's in DE which I can no longer download since the January aggregator debacle at Fictionwise. I'd like to be able to put them into Calibre with the rest of my books.

I have 3 versions of the key script: 4.4, 4.5 and 5, 4.5 being the only one that appears to function, but attempting to use for single books gets me the usual answer about error decrypting book session key, when I try using the 7.4 for PDF's.

Have since found the 3.3 version tools and tried 5.4 key with the 7.8 with no better results.

Hi,

If you can open and read those specific PDF's in ADE on your Mac or PC, then the "tools" should be able to help you convert them. You need to try with PDFs taken directly from your your ADE ebooks folder (to make sure they were properly encrypted by ADE). The latest is "tools_v3.3.zip". Google ApprenticeAlf and read that website. There are many helpful instructions there to get you going.

That's what I did, but I always get the error decrypting book session key anyway

Hi,

So you ran read that exact pdf with ADE no problems on that very machine and account, but when you copy that pdf file out of "My Digital Editions" folder on your Mac or PC and input it to the correct tool taken from tools_v3.3.zip you get an error?

What version and which tool are you trying with? I suggest you report your exact error message, what version you are trying with, if your adeptkey.der was properly created, etc, in the Comments at the bottom of the ApprenticeAlf blog and I am sure someone there can help you.

Hi,

Alf retired but the site does live on in reduced form and the comments are enabled on the very last topic on his blog. That is where you need to ask if you want help, I think.

Try the Calibre plugins as described on Alf's blog.

Hi ThePage,

I see there is now a new version of the tools (v3.4) posted with an updated ineptpdf (v7.9) that changes the logic for determining book session keys.

So if you are still having problems, you might want to grab that new version and check to see if it fixes your issue.

My problem was at least partially responsible for the new versions.

A special hack that was concocted to get a read-out of my book-key data unexpectedly handled the DRM removal on my 90 or so PDF's, but required handling them singly as the new plug-in was still
"under construction"

I just finished removing the plug-in which hadn't worked for me, but will add the new one if I ever find that I'll be needing it.

While this has concluded my DRM removal phase in cataloguing books, I still have a few loose ends.

I have twenty books in LIT format which are only readable WITH the DRM.
Downloading new copies did NOT improve matters.

Where should I look, or who should I talk to in search of help in sorting these out into proper readability without the DRM?
