README

        

DMG2IMG is a tool which allows converting Apple compressed dmg 

archives to standard (hfsplus) image disk files.

This tool handles zlib and bzip2 compressed dmg images.

USAGE:

    dmg2img [-l] [-p N] [-s] [-v] [-V] [-d]  []

or

    dmg2img -i  -o 

    

It is derived from dmg2iso v0.2c by vu1tur 

NOTES: 

1. An equivalent command under Mac OS X would be:

hdiutil convert  -format UDTO -o 

2. Under linux, the image disk file can be mounted with the commands

modprobe hfsplus

mount -t hfsplus -o loop  /mnt

[normally, only 'root' might be able to do this]

3. Windows users should be able to open the image disk file with UltraISO.

COMPILATION:

The default included Makefile is for Linux/gcc. The development files 

in zlib-dev and libbz2-dev are needed to compile dmg2img, and those

in openssl-dev are needed to compile vfdecrypt.

CHANGELOG:

1.0     3 August 2007

        * Initial version 

1.1     4 August 2008

        * Fixed segfault bug occurring when decompressing certain dmg files

          beyond the actual end of the file (due to not correctly setting

          the size of the compressed parts ...)

        * Added slightly modified vfdecrypt utility from 

          Weinmann-Appelbaum-Fromme in order to decrypt encrypted dmg files.

1.2    17 September 2008

        * Fixed segfault bug due to buffer overflow (buffer sizes

          incorrectly set, resulting in insufficient memory allocation).

        * Fixed most compilation warnings - remaining ones are

          irrelevant with standard compilers.

	

1.3    19 September 2008

        * Further fixes which (hopefully) enable dmg2img to work on

          dmg archives of arbitrary size, while reducing RAM usage a lot.

        * A lot of thanks to Alfred E. Hegge and Randy Broman for testing

          and reporting bugs.

1.4     5 April 2009

        * Applied patch from Vladimir 'phcoder' Serbinenko which brings

          correct handling of 64bit integers in koly signature and

          plist data, and should enable dmg2img to work on huge 

          archives > 4GBytes (tested by 'phcoder').

        * Added support for dmg archives involving bzip2 instead of zlib

          compression (this has not received much testing yet, as those

          archives are still unfrequent).

        * Many thanks to Pierre Duhem for useful hints.

1.4.1   6 April 2009

        * Fixed a bug in writing the output file that caused some DMG images

          to convert to a broken unmountable IMG image.

1.5     8 April 2009

        * Fixed a bug in parsing plist for image partitions.

        * Added support for ADC-compressed dmg images.

1.5.1  11 April 2009

        * Added missing zero block type.

        * Small fixes and clean up.

1.6    15 April 2009

        * Added support for dmg images that only have binary resource fork

          but no XML plist. 

        * Refined koly block processing.

        * Fixed a bug in finding the offset for the next compressed block

          when offsets are defined relative to the current partition.

        * Fixed broken progress indicator.

        * Added detection of images with GUID Partition Table and respective 

          mount commands in linux.

1.6.1  12 August 2009

        * Fixed a bug in handling large files on win32 systems.

1.6.2  24 March 2010

        * Fixed a bug in processing a terminal block type.

        * Added periodic flushing of debug log file.

1.6.3  07 April 2012

        * Added option -l to list partitions

        * Added option -p to extract only specific partition

        * Added support for a rare case scenario of koly block being at the

          the beginning of the image (thanks to Friik)

1.6.4  25 April 2012

        * Compilation bugfix (Linux)

1.6.5  23 July 2013

        * Fixed a bug in handling some types of dmg files
