The link has already been posted by @TobiasKienzler. Also, a hint was the big green sign in the main page that said Open Source.

Wasn't AdBlock Plus open source? (;

Search for "YOUR_PREFERRED_ANTIVIRUS livecd"? LiveCD is a bootable disk (at least in the Linux world), so you can analyze the system while it's off.

You cannot just bruteforce bcrypt efficiently, even with GPU...

comment Encrypt user data when they log in with Facebook, Gmail, etc
@Ramhound, how would the compromise of the salt and hash allow for bruteforce attack? bcrypt uses hash stretching, which means that each hash takes 0.1s in my system (slow). That means that, even in a 100 times faster system it'd take years to find the original hash of one single password providing it's at least 6 digits with alphanumeric+symbol. There's an excellent Q&A already here

I am looking more for some self-containment system that doesn't require a general verification system, but rather is user-dependent. As I specified in the edit, I want it to be secure even for full read access to the code/database, in a similar fashion as how bcrypt works.

comment Encrypt user data when they log in with Facebook, Gmail, etc
I want to protect user's data from everyone, including admins or/and a thief with the database. I would rather prefer a user-specific salt instead of a pepper, it should make things more secure against a rainbow table on the ids. I don't normally store the user's id from facebook. However, I do store the email. In case of db theft, that'd be known, and a simple email search should yield back the user's id, thus I consider the id as an invalid secret...

comment Does bcrypt on top of md5 reduce its security?
@CodesInChaos (about 1st comment), there's a point as it theoretically could already have been leaked. About 2nd, that was the actual point of my question, if there was any actual gain from using only bcrypt(pass) over bcrypt(md5(pass)) (note bcrypt auto-generates a salt, so it's okay not to pass it).

I consider the correct answer yours, @Adnan, but only after complementing it with the one from CodesInChaos.

I was just learning about securing the users but never really about securing my site. That's a great piece of advice, thank you @CodesInChaos

comment What does Mark Shuttleworth mean by “we have root”?
@WarrenP , nope, with the scopes you are sending your search data straight to their servers. This means that you don't know how they're storing/using every single character that you write in the dash, hence the privacy concerns.
