comment Why is it a security problem not to update one's browser?
Because otherwise you can find front-end developers hunting you down with a keyboard for using IE6

comment Is my custom password hashing algorithm insecure?
TL;DR yes, it is insecure. Don't roll your own hashing algorithm

comment How do web email clients store my passwords from other providers?
I'm just saying that there's the possibility that the master passwords is derived from my main password and stored in cookies; so it can be retrieved from cookies OR when I log in.

comment Should I get an antivirus for my Mac?
References for [...] there were historically so few viruses around for Mac is because their market share was so small. please? I had understood that it had to do more with, historically, windows being run as admin and *nix systems not being root by default.

comment How to store passwords securely in my server?
@eric I haven't, I've searched for previous questions in security.SE since it seems like the good place to ask about security. Thanks for the link.

comment How to store passwords securely in my server?
@eric, no, they don't. However, this is a slightly broader question; it's not about supporting my uni's email, it's about supporting imap securely.

comment Allowing users to input a safe subset of HTML
What would happen if I only wrote </body>? This should give you an idea of what can go wrong. For the images/link, you can put them in a query and manually check them (before or after allowing for public viewing).

@JohnDeters, your comment could be perfectly the accepted answer so future visitors (as myself) have a clear answer, if you want.

comment Is it possible to increase the cost of BCrypt or PBKDF2 when its already calculated and without the original password?
+1 for the scheme I describe above is homemade crypto, and that's bad. I can get away with it because I am totally awesome, but this cannot be promoted on a general basis

comment Hashing the cookie token for persistent login
The sha256 hash is easier in PHP, however you are right, I'm using already bcrypt so I better stay coherent. The thing with bcrypt (at least for PHP) is that I can change how long it takes for each hash. So I guess now the question would better be, how long it needs to take for each hash. I find 0.5 seconds too high, but I'll ask in another question here, thank you (:
