md5 differences

[Python]

Hi there!

I'm trying to match the results of an md5 checksum done in a tcsh shell.
I keep getting different results and can't find anything on google...

here's an example:

Arno@Computer:~ % echo "hello" | md5
b1946ac92492d23 47c6235b4d26111 84

Arno@Computer:~ % python
Python 2.5.1 (r251:54863, Jan 17 2008, 19:35:17)
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright" , "credits" or "license" for more information.

>>import md5
>>md5.new("hell o").hexdiges t()

'5d41402abc4b2a 76b9719d911017c 592'


How do I get the same results?

thanks
Arno

Checksum the same string.

>>md5.new("hell o\n").hexdigest ()

'b1946ac92492d2 347c6235b4d2611 184'

hmm and this then:

Arno@Computer:~ % echo "test" test.txt

Arno@Computer:~ % md5 test.txt
MD5 (test.txt) = d8e8fca2dc0f896 fd7cb4cb0031ba2 49

'90364ed45b452d 43378629c20543a 81d'


even
echo -n "hello" | md5
doesn't return the same number

You're going to smack yourself on the head over this one. :-)

>>md5.new(open( "/Volumes/data/Arno/test.txt").read ()).hexdigest()

Works for me:

>>import md5

>>md5.new(f).he xdigest()

'd8e8fca2dc0f89 6fd7cb4cb0031ba 249'

IOW, don't pass the path to the file to md5.new, but the contents
of this file.

The strange thing is that

>>md5.new("/Volumes/data/Arno/test.txt").hexd igest()

returns '8dd66a1592e2a8 c3ab160822fb237 f4d' on my machine.

That's the digest of the string "/Volumes/data/Arno/test.txt".
It's not supposed to match the digest of the string "test\n".

>>md5.new(open( "test.txt").rea d()).hexdigest( )

'd8e8fca2dc0f89 6fd7cb4cb0031ba 249'

$ md5sum test.txt
d8e8fca2dc0f896 fd7cb4cb0031ba2 49 test.txt

$ echo "test" | md5sum
d8e8fca2dc0f896 fd7cb4cb0031ba2 49 -

>>md5.new("test \n").hexdigest( )

'd8e8fca2dc0f89 6fd7cb4cb0031ba 249'

even
echo -n "hello" | md5
doesn't return the same number

Not the same as _what_?

>>md5.new("test ").hexdiges t()

'098f6bcd4621d3 73cade4e832627b 4f6'

$ echo -n test | md5sum
098f6bcd4621d37 3cade4e832627b4 f6 -

I guess it will be the same for vast majority of us ;-)
The question is why is it '90364ed45b452d 43378629c20543a 81d'
for the OP? :-)

The smart money is betting on "because the OP goofed when he
was cutting/pasting stuff from his terminal window into his
posting."

I did! I did!

my bad... i cut some crap from the path to make it a bit easier to read
but that was before the time i knew it was checksumming the
actual path in stead of the contents of the file.
So I figured it didn't matter...
