wrong md5 checksum

[kkwweett]

Hi,

the download page (http://www.python.org/download/releases/3.0/) for
Python 3000 shows :

9119625244b17aa35ed94b655a2b2135 13491200 python-3.0b1.msi

but I got

9119625244a57aa35ed94b655a2b2135 13491200 python-3.0b1.msi

(44a57 rather than 44b17 )

with several md5 checkers ( MdChecker (http://getmd5checker.com/) or a C
prog I've written)

what's wrong ?

Wrong md5 checksum even with Python2.5 :


import md5
m=md5.new()
message=open("python-3.0b1.msi","rb").read()
m.update(message)
m.hexdigest()

Does anyone know what can be done to decide wether the file is corrupted
or the checksum given is wrong ?

 

[kkwweett]

A. an error in the software that computed the value for the web page,
B. a transcription error in putting the checksum on the web page,
C. accidental corruption of the file, or
D. a deliberate attempt to substitute a file with a similar MD5 sum.

It seems that the answer is probably B. But, according to the release
website manager, a mystery remains :

Marcin Kowalczyk pointed out in a follow-up to the above that the
replacement of 'a5' with 'b1' could have been part of a global
search/replace that would have been correct everywhere else on the page.
Thus case C. Barry remembers doing some such.

Lesson. Take care with blind global replacements.
