comment Can older or custom web browsers override the same origin policy?
@PeterStuart I initially misunderstood your threat model, and have added an additional paragraph. Assuming the SOP will protect your site is like assuming that because a person has seat belts in his car he can't get out and attack you. (The seat belt is there to protect the driver of the car, not you.)

Regarding your redirect-to-HTTPS comment, it's worth noting to the OP that Google uses HSTS, which eliminates the redirect entirely, after the first visit. (Of course, the first visit is still vulnerable in the way described here.)

comment What do the dots and pluses mean when OpenSSL generates keys?
I'm curious: where did you get this information? I don't doubt it's correct, but I haven't been able to find a manual page or other documentation about it. I did a Google search for "A potential prime number was generated" and found a blog that has the exact same verbatim information, so I assume it's quoted from somewhere, but I haven't found any official source (maybe source-code comments?).

@AlfredoOsorio Ah, yes, your latest edit makes the password concern much clearer; I think I started my answer before that edit. I'll look up IEEE 802.11 rules and make an edit.

comment Get info encrypted across a MITM proxy
@EricDong From my reading of your comment, you've identified two undesirable outcomes of the SSL bad-cert warning: 1) the user ignores it or 2) the user doesn't ignore it and the communication fails. I don't think either of these problems is solvable (and certainly eliminating both in the same protocol seems quite impossible). The insolubility of problem #1 is obvious enough: users can always send data when they shouldn't (e.g., by violating the protocol!). Problem #2 is also insolvable: if an attacker can intercept a connection, they can quite easily stop communication completely.

comment Is it safe to disable SSH host key checking if key-based authentication is used?
@Adnan Just to speak from personal experience, I've seen that error message many times when connecting to different machines that used the same dynamically-assigned IP on a local network (e.g., my SheevaPlug was 192.168.1.101 yesterday, but today that address refers to my laptop), which seems to be a direct analogue to what the OP is doing here. From tthat experience I personally don't find anything suspicious, but -- having read your comment below -- I can see how your reading of the spec would make you suspect misrepresentation.

@Adnan The problem case here isn't with a new IP address. The problem is a new server accessed through a repeat IP. (For example, Amazon assigns your first VM some IP; after you destroy it, a future VM you create may be given the same IP address, but the new VM will have a new keypair.)
