How can I make sure I am accessing (online) or have downloaded (as an HTML file or from GitHub) a legitimate, trustworthy version of bitaddress.org?
In other words, how can I make sure no hacker has modified something at bitaddress.org or in the GitHub files in order to be able to capture generated keys?
I have read somewhere something about computing the "hash" and/or "verifying the signature" or something like that. I'm not at all familiar with all this.
I think the same question would apply for bitcoinpaperwallet.com, too.
