Hi

I'm not sure if I'm being really daft or what but I seem to be in a
chicken/egg situation.

I have been trying to include a file integrity check for my
application using md5 hashing of the file. The problem is every time I
include the hash value, it changes the file’s hash value and thus the
compare fails!

I have read that it’s a good thing to do as it provides another trap
that potential hackers have to overcome, and also verifies that the
app has been downloaded without error. With that in mind I would have
preferred not to have saved the value to file, as I believe its easier
for a hacker to monitor for a file read, than to find the code if its
triggered from a timer and hardcoded?

Thanks
Pete
