comment How to generate a superkey to decrypt strings
A public key should be public. If the server is the only one to know the public key, why not using a symmetric key ? Encrypt the message with the server private key is pointless, as everyone should know its public key. By the way, I don't think this answers the question.

comment Get the browser history without using a browser
It depends on the web browser. Best is to ask google (eg. "firefox debian history file"). However the history might be ciphered (or serialized, which makes it hard to read with a simple text editor).

comment Online Shopping password keylogger risk
Security is a matter of trust. The client side of a website can be audited by anybody. So I won't fear any popular website for key logging or malicious actions. Well, not actually, however I would first be aware of the web browser (including plugins) and the operating system. Especially if it is proprietary software... I'm sorry I don't understand what you mean "we can easily catch them using the registered address".

comment How can I identify this hash?
I think the best way to get the hash function is to look for "[linux distribution] passwd hash algorithm" on your favorite search engine. Then good luck to find a dictionary containing this specific hash. If I were you, I would RTFM either to get the root password or to get the way to change it. If this is not possible, the vendor might have a good reason. PS: Basically, uppercase letters are not meant to shout out aggressively.

comment How can I identify this hash?
If this is your router, you should not have to decipher the root password to get full privileges. Moreover, as you say, the password is not encrypted but hashed. The difference is that a hash function is not reversible. So you can't get the original data from the hash, unless you find the correspondence in a dictionary

comment How is NFC tags copy prevented?
As far as I know, a NFC tag is unpowered. So embedding a microprocessor doesn't seem possible.

I think the output of nmap could be useful.

comment Is password authentication worse that signed messaging if done over SSL?
"Therefore the server learns the password." Can't the password be hashed by the client, instead of by the server?

Think about encrypting passwords exchange then. And generate strong passwords as well.

comment How is distributed computing security ensured?
I understand that my question might be a bit too broad. I will try to refine it. However I have absolutely no idea of how this is possible and I am pretty stunned that distributed computing with "untrusted machines" works. So I'm looking for an answer that could ease my amazement. Maybe a concrete example?

comment Is it a good idea to have a “master” password?
Theses links only shows me that I am not the only one who have had this idea (which is not a big surprise). But I don't see how it answers my question.

comment Are passwords stored in memory safe?
You're absolutely right. That's also why I (or at least try to) only run free software my computer.

comment Are passwords stored in memory safe?
@OmarKohl That's what I did for my script. I first ask the password to unlock the keyring. Then I encrypt a random session password I send to the remote computer. And once I'm sure it received the new password I overwrite the password of the keyring. If it doesn't really solve the problem, it limits the time when the actual persistent password is stored in memory.

"virtual machines and cloud computing cannot be ultimately safe". I've always been skeptical about cloud computing.
