By default, the hexdigest will read the file in "OS Compatible" mode (as opposed to "portable" mode). This is made clear in the "--help" option of the "shasum" command, which is packaged with Digest::SHA1.

In my tests on Windows7, the shasum command with the "-p" option produced the same results as the default call to the hexdigest() method.

The "fciv" command, apparently reads the file in "binary" mode, which is also the default for the "shasum" command.

In order to be compatible, you will need to add "binmode $filehandle;" prior to the addfile() call, as Corion(++) has independently suggested above. I have tested this, and it works.
