Question

I made a script that crawls through a domain, and I want it to determine if there were any unauthorized modifications. For static pages I can simply compare to a pre-set hash value, but for dynamic-length pages, what’s a good way to check if any significant changes were made?

Sorry if it sounds dumb.

Answer 1

You could download the pages locally, then use diff to check the length of the answer. Eg,

diff old_version new_version | wc

which will give you a summary of the length of the changes.
