How can I get a snapshot of a website that can serve as an evidence of its current state?
There is a website that requires authentication that I want to take a snapshot of it as a proof that the site did list my information at this time. So in case they take down my info, I could say I have a proof that they did have my info there before they removed it.
I could take a screenshot of it but it wouldn't be a solid evidence because screenshot image could be said to be photoshop'ed.
What would be a good way to do this?
