Using AFF Tool Under Microsoft Windows (Win32)


There are two ways to use AFFLIB with Windows: you can download the
pre-compiled executables, or you can compile your own.  The advantage
of the pre-compiled executables is that they work. The advantage of
compiling the executables yourself is that you can modify them.

Downloading and Installing
==========================
You can download the current version of AFF Tools from:

    https://github.com/simsong/AFFLIBv3

The ZIP file contains:
    * pre-compiled executables for AFF Tools
    * lib32eay.dll, the OpenSSL DLL (cryptography support for AFFLIB)
    * bulk_extractor jar and bat file. (Use the bat file to run the jar file)

Install these tools by:

1. Unzip the archive into the c:\afflib directory.
2. Add c:\afflib to your system PATH directory by:
   a. Opening the System control panel.
   b. Clicking the "Environment Variables" button.
   c. Adding "c:\afflib;" to the beginning of the PATH environment variable.

Compiling under Windows

There are three ways to compile for Windows:
1 - Cross-compiling from a Linux or Mac system with mingw.
2 - Compiling natively on Windows using mingw.
3 - Compiling natively on Windows using cygwin (untested)

Cross-compiling from Linux or Mac using MINGW:
*********************************************

* Cross-compiling works fine, but it does not include the version 4.x
  GCC compiler and pthreads does not appear to work properly.

* We used to install with mingw cross-compiling, but that created problems with multi-threading


Compiling natively under Windows with MINGW:
*******************************************

  Download the Windows Resource Kit from:
  http://www.microsoft.com/downloads/details.aspx?familyid=9d467a69-57ff-4ae7-96ee-b18c4790cffd&displaylang=en

  Download and run mingw-get-inst-20101030.exe (or whatever version is current),
  selecting all options including these:
    C Compiler, C++ Compiler. MSYS Basic System, MinGW Development Toolkit.
  When selecting the installation path to MinGW, Do not define a path with spaces in it.

  Start the MinGW32 shell window.

  Download the latest repository catalog and update and install modules required by MinGW
  by typing the following:
  mingw-get update
  mingw-get install g++
  mingw-get install pthreads
  mingw-get install mingw32-make
  mingw-get install zlib
  mingw-get install libz-dev

  Install the libraries in this order:
    * expat (http://sourceforge.net/projects/expat/)
    * openssl (http://openssl.org)

  For each library:
   - download
   - ./configure --prefix=/usr/local/ --enable-winapi=yes
   - make
   - make install

   For openssl, run "./config --prefix=/usr/local" rather than configure.

   Don't make directories in your home directory if there is a space in it! 
   Libtool doesn't handle paths with spaces in them.

  If OpenSSL is installed in /usr/local/ssl, you may need to build other libraries with:
  ./configure CPPFLAGS="-I/usr/local/include" -I/usr/local/ssl/include" \
              LDFLAGS="-L/usr/local/lib -L/usr/local/ssl/lib"

  Most libraries will install in /usr/local/ ; you may need to add -I/usr/local/include to CFLAGS
  and -L/usr/local/lib to your make scripts

  Still problematic, though, is actually running what is produced. Unless you link -static you will have
  a lot of DLL references. Most of the DLLs are installed in /usr/local/bin/*.dll and /bin/*.dll and elsewhere,
  which maps typically to c:\mingw\msys\1.0\local\bin and c:\mingw\bin\




Compiling your own copy:
=======================
We compile with mingw. Download and install MSys.

Working with the tools
======================

If you are working with an encrypted disk image, set the environment
variable AFFLIB_PASSPHRASE to be the passphrase that should be used
for decryption.

   % set AFFLIB_PASSPHRASE="this_is_my_passphrase"

Displaying the metadata with a disk image:

   % afinfo.exe filename.aff	  

To convert an AFF file into a RAW file, use:

   % affconvert.exe -e raw filename.aff


To reliably copy an AFF file from one location to another:

   % afcopy.exe  file1.aff  d:\dest\path\file2.aff


To compare two AFF files:

   % afcompare file1.aff file2.aff


To fix a corrupted AFF file:

  % affix badfile.aff


To print statistics about a file:

  % afstats.exe filename.aff



Diskprint
=================
An exciting feature in AFF 3.5 is the ability to rapidly calculate and
verify the "print" of a disk image. A print is constructed by
computing the SHA-256 of the beginning, end, and several randomly
chosen parts of the disk image.

To calculate the diskprint and store it in a file:

   % afdiskprint myfile.iso > myfile.xml

To verify a diskprint

   % afdiskprint -x myfile.xml myfile.iso
