comment Why is this certificate valid for so many domains?
@jdoe Because that requires SNI, and is a rather long story. This answer on Serverfault explained it for me. If that's still not clear, let me know! Edit: And also, from a security perspective, the server would still need to know all those certificates (or at least a number of them). If you can grab one, you can probably grab all private keys stored there.

comment What is the problem with chain hashing?
@acidzombie24 Because a salt is complementary to iterating hashing (or chaining). You shouldn't do either one or the other, you should do both. Or best of all, you don't mess around with security but use something proven like bcrypt or PBKDF2.

+1 Very short, but nailed exactly what I wanted to know when reading the question title ^^

They aren't sharing their own key, we hope anyway, but if you can inject scripts you own the page.

Try sending this packet to your server: GET / HTTP/1.1\r\nHost: example.com\r\nX-FORWARDED-FOR: cookies!\r\n\r\n Congrats, you just forged your own IP to 'cookies'!

comment Is truecrypt a good choice to work with file that are generated and manipulated via browser
A bit vague first question. Truecrypt encrypts data with an algorithm you can choose and a password or keyfile you can set. What does a browser have to do with this? Anything transmitted over HTTP can be read and tampered with, I guess you know that. And what do server-side languages have to do with the generation of files in a browser.. and then have something to do with security?

comment Roundcube login only looks at first 8 characters of password entered?
I'm quite sure WebFaction is to blame, not RoundCube.

For a template, I think it's hard to autogenerate the damage that was done.

comment Manually adding 's' to 'http'
It'll show grey https with a yellow warning icon on mixed content. But yeah I guess non-tech people wouldn't know and ask the same question as is asked now.

comment Manually adding 's' to 'http'
Note that you can also get free certificates, purchasing one from a company like Verisign isn't needed to make the certificate trusted. The sysadmin either doesn't know this or doesn't care.
