MD5 problem

[fargo]

Hi.

I'm in trouble with the md5 module.

Under Linux, it's ok, I get real signatures.

The problem is under Windows XP, with some kind of files.

If I use the md5 module with .txt files, it'ok.

The Problem comes from the .msg files. I get the same signature for
every .msg file I try to hash with the md5 algorithm. I think some
character are strange for python, and makes it stop before the end of
the .msg file.

So, my question is : Do anybody have a solution to this problem ? (I can
post my source code if needed)

Thank you.

That sounds like you opened the file in text mode. For things like this
it is better to open it in binary mode: file(filename, 'rb')

FYI: the character that was strange for Windows (not Python) was
chr(26), or Ctrl-Z, or end-of-file, which is special for files opened as
text instead of binary.
