\cf0 DeDRM_X.X is an AppleScript droplet that allows users to drag and drop ebooks or folders of ebooks onto the DeDRM droplet to have the DRM removed. It repackages the all the "tools" DeDRM python software in one easy to use program that remembers preferences and settings.\
|
||||
\
|
||||
It should work without manual configuration with Kindle for Mac ebooks and Adobe Adept epub and pdf ebooks.\
|
||||
\
|
||||
To remove the DRM from standalone Kindle ebooks, eReader pdb ebooks, Barnes and Noble epubs, and Mobipocket ebooks requires the user to double-click the DeDRM droplet and set some additional Preferences including:\
|
||||
\
|
||||
Mobipocket, Kindle for iPhone/iPad/iPodTouch: 10 digit PID\
|
||||
Kindle (not Kindle Fire): 16 digit Serial Number\
|
||||
Barnes & Noble key files (bnepubkey.b64)\
|
||||
eReader Social DRM: (Name:Last 8 digits of CC number)\
|
||||
Additional Above Adept key files (.der)\
|
||||
Location for DRM-free ebooks.\
|
||||
\
|
||||
Once these preferences have been set, the user can simply drag and drop ebooks onto the DeDRM droplet to remove the DRM.\
|
||||
\
|
||||
This program requires Mac OS X 10.5, 10.5 or 10.7 (Leopard, Snow Leopard or Lion)\

\cf0 DeDRM is an application that packs all of the python drm-removal software into one easy to use program that remembers preferences and settings.\
|
||||
It works without manual configuration with Kindle for Mac ebooks and Adobe Adept ePub and PDF ebooks.\
|
||||
\
|
||||
To remove the DRM of Kindle ebooks from eInk Kindles, eReader pdb ebooks, Barnes and Noble ePubs, or Mobipocket ebooks, you must first run DeDRM application (by double-clicking it) and set some additional Preferences including:\
|
||||
\
|
||||
Kindle (not Kindle Fire): 16 digit Serial Number\
|
||||
Barnes & Noble ePub: Name and CC number or key file (bnepubkey.b64)\
|
||||
eReader Social DRM: Name and last 8 digits of CC number\
|
||||
Mobipocket: 10 digit PID\
|
||||
\
|
||||
A final preference is the destination folder for the DRM-free copies of your ebooks that the application produces. This can be either the same folder as the original ebook, or a folder of your choice.\
|
||||
\
|
||||
Once these preferences have been set, you can drag and drop ebooks (or folders of ebooks) onto the DeDRM droplet to remove the DRM.\
|
||||
\
|
||||
This program requires Mac OS X 10.5 or above. \

# Changelog
|
||||
# 0.01 - Initial version
|
||||
# 0.02 - Huffdic compressed books were not properly decrypted
|
||||
# 0.03 - Wasn't checking MOBI header length
|
||||
# 0.04 - Wasn't sanity checking size of data record
|
||||
# 0.05 - It seems that the extra data flags take two bytes not four
|
||||
# 0.06 - And that low bit does mean something after all :-)
|
||||
# 0.07 - The extra data flags aren't present in MOBI header < 0xE8 in size
|
||||
# 0.08 - ...and also not in Mobi header version < 6
|
||||
# 0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
|
||||
# 0.10 - Outputs unencrypted files as-is, so that when run as a Calibre
|
||||
# import filter it works when importing unencrypted files.
|
||||
# Also now handles encrypted files that don't need a specific PID.
|
||||
# 0.11 - use autoflushed stdout and proper return values
|
||||
# 0.12 - Fix for problems with metadata import as Calibre plugin, report errors
|
||||
# 0.13 - Formatting fixes: retabbed file, removed trailing whitespace
|
||||
# and extra blank lines, converted CR/LF pairs at ends of each line,
|
||||
# and other cosmetic fixes.
|
||||
# 0.14 - Working out when the extra data flags are present has been problematic
|
||||
# Versions 7 through 9 have tried to tweak the conditions, but have been
|
||||
# only partially successful. Closer examination of lots of sample
|
||||
# files reveals that a confusion has arisen because trailing data entries
|
||||
# are not encrypted, but it turns out that the multibyte entries
|
||||
# in utf8 file are encrypted. (Although neither kind gets compressed.)
|
||||
# This knowledge leads to a simplification of the test for the
|
||||
# trailing data byte flags - version 5 and higher AND header size >= 0xE4.
|
||||
# 0.15 - Now outputs 'heartbeat', and is also quicker for long files.
|
||||
# 0.16 - And reverts to 'done' not 'done.' at the end for unswindle compatibility.
|
||||
# 0.17 - added modifications to support its use as an imported python module
|
||||
# both inside calibre and also in other places (ie K4DeDRM tools)
|
||||
# 0.17a- disabled the standalone plugin feature since a plugin can not import
|
||||
# a plugin
|
||||
# 0.18 - It seems that multibyte entries aren't encrypted in a v7 file...
|
||||
# Removed the disabled Calibre plug-in code
|
||||
# Permit use of 8-digit PIDs
|
||||
# 0.19 - It seems that multibyte entries aren't encrypted in a v6 file either.
|
||||
# 0.20 - Correction: It seems that multibyte entries are encrypted in a v6 file.
|
||||
# 0.21 - Added support for multiple pids
|
||||
# 0.22 - revised structure to hold MobiBook as a class to allow an extended interface
|
||||
# 0.23 - fixed problem with older files with no EXTH section
|
||||
# 0.24 - add support for type 1 encryption and 'TEXtREAd' books as well
|
||||
# 0.25 - Fixed support for 'BOOKMOBI' type 1 encryption
|
||||
# 0.26 - Now enables Text-To-Speech flag and sets clipping limit to 100%
|
||||
# 0.27 - Correct pid metadata token generation to match that used by skindle (Thank You Bart!)
|
||||
# 0.28 - slight additional changes to metadata token generation (None -> '')
|
||||
# 0.29 - It seems that the ideas about when multibyte trailing characters were
|
||||
# included in the encryption were wrong. They are for DOC compressed
|
||||
# files, but they are not for HUFF/CDIC compress files!
|
||||
# 0.30 - Modified interface slightly to work better with new calibre plugin style
|

# 0.31 - The multibyte encrytion info is true for version 7 files too.
