Edit: beachaccount: Financial institutions not using DHE is not a logically sound counter to "There's nothing wrong with using DHE algorithms, particularly if you're going to be transferring financial secrets around." While those institutions may chose not to, there is nothing wrong with others choosing otherwise. Additionally, patchy security on the part of one operator certainly is not a logically sound argument against this.
Furthermore, in the future, actually reply to a post in order to reply to a post. Not doing so unnecessarily confuses the flow of conversations (posts are not scarce resources).
The implication being that since they were sending the information in the clear in a separate part of their system, that they were wrong in configuring their https site as they did. I object to that conclusion.
Furthermore, one particular site using https in a particular mode when they don't need to use https at all is still not a logical argument against other sites using https with those ciphers.
Burgerbrain: PayPal.com, CitiCards.com, 2checkout.com, and many payment processors all use RC4-SHA or AES256-SHA. You are wrong.
