    He could always encrypt the password in order to transfer it, decrypt it after it's transferred, and then hash it to compare with the database content.

      No, not joking. HTTPS has been proven insecure (there was a big kerfuffle over that realization a couple of years ago), so why solely rely on it? It shouldn't be difficult to set up.

        That's a pretty bold claim. Do you have a link to back that up?

          There were some protocol downgrade attacks, but that should not happen on a modern machine. So, which insecurity?

            I don't recall specifically. In the end, there's absolutely nothing wrong with an additional layer of security. I was just tossing the idea out there.

              No, but I'm almost positive you have access to google. I don't recall the specifics.

                There is! It adds complexity, a point of failure, and hence, a point of attack. Think of it as using two condoms; you think you're safer, while the integrity of both lubbers is not guaranteed.

                  I've seen a few conspiracy nuts claiming that HTTPS is an NSA / Google plot to destroy the internet, but their claims are just laughable. :) Troy Hunt: Don't Take Security Advice from SEO Experts or Psychics[^] HTTPS Anti-Vaxxers; dispelling common arguments against securing the web[^] Beyond that, as Eddy said, there were a couple of downgrade attacks which would make your request slightly less secure - but still more secure than not using HTTPS in the first place. Those have been fixed now, but I suppose there could be others which haven't been discovered yet. But as Griff said, encrypting things in Javascript means the encryption key has to be public, so it doesn't really add any benefit.

                    We're in the C# forum so you'll have to excuse the assumption that we were talking about C#. JavaScript is evil and should be avoid at all costs. I equate it to using Active-X in regards to evility.

                        Trouble is that when you start talking about passwords, and "back end" or client / server architecture, nearly all the time you are talking about a javascript based client (which while execrable is vastly safer than Active-bloody-X was) - and that means public source code, and public encryption. Nasty. X|

                          You're confusing specific issues with general insecurity. HTTPS over SSL has been prohibited,. TLS should use version 1.2 or later (with no fallback to SSL.) Heartbleed was a vulnerability in OpenSSLs implementation of TLS heartbeats, which has been fixed. HTTPS over TLS is secure (for now; all security can, and will, be broken in time.)
