DigestIT 2004

digestIT 2004 is a free Windows program that allows you to generate an MD5 message hash or an SHA-1 hash for a file. An MD5 message hash, aka MD5 sum, and a SHA-1 hash are unique hexadecimal numbers that allow you to determine if a file has been altered. A silent installer and uninstaller for digestIT 2004 is provided below. Once it is installed, you can right-click on a file in Windows and choose "digestIT 2004" to generate either an MD5 hash or a SHA-1 hash. The software then provides you the opportunity to copy the hash to the Windows clipboard or save it to a file.

<package

</package>

The default installatation is "%PROGRAMFILES%\digestIT 2004" at least for Windows XP. I found it was installed in "C:\" when I installed it on a Windows 2000 Professional SP 4 system using wpkg, however. You can specify the installation directory in the digestIT 2004 entry in the packages.xml file by using an entry like the following in the install section:

<install cmd='msiexec /i "%SOFTWARE%\digestIT2004\digestIT 2004.msi"
 /qn TARGETDIR="%PROGRAMFILES%\Utilities\File\digestIT 2004"' />

You could use the entry above to install the program into "C:\Program Files\Utilities\File\digestIT 2004". The installation process would create any of the subdirectories that did not exist.
