Try editing as follows: change
> f = open(fname, "rb")
> while 1:
> block = f.read(1024*1024)
> if not block:
> break
> # generate the hash
> m.update(block)
> f.close()
to:
f = open(fname, "rb")
nbytes = 0
while 1:
block = f.read(1024*1024)
nbytes += len(block)
if not block:
break
# generate the hash
m.update(block)
f.close()
print '%d bytes processed'
As Adam DePrince noticed, the md5 checksum you generated was that of
an empty file. So the above should tell you whether you're actually
processing any input; if you don't get the expected number of bytes,
debug from there.
