@SPRBRN: I had thought about suggesting a QR code, but not all would be able to read it.

comment Why is it a security problem not to update one's browser?
Could you give examples of what exactly could happen? How common are these security holes?

comment Is there a value in using portable programs on a USB key?
It makes sense that there would various logs. I hadn't thought about that. But will there be any content from the file on the hard drive? So, if I for example edit a file located on a USB key with, for example portable notepad also located on the USB key, is it likely that any parts of the file makes it onto the hard drive?

comment Keepass Dictionary Attack Protection Strategy
From the Security page that you linked to, it sounds like it is all about increasing the time needed to try one key. Also, if the N and C is known, then I would guess that one could just precompile a list of list of keys. So if you want to attack several databases at the same time, you would only have to perform the hashing ones. In that sense the encryption with a random AES key works like a salt. But maybe someone with greater wisdom can say more.

@KnightOfNi: Yes, I am guessing that this is what Schneier meant.

comment Methods used to reverse a hash
Thanks for the answer. I forgot to mentioned that I think that the exhaustive search (brute-force) is much like the dictionary method.

Thanks for this answer. I hadn't thought of your first point. Simply storing the first couple of bytes seem to work.

@Iszi: Would you write an answer? (I would like to hear how safe this method is. It sounds like you are saying that it is not safe at all).

comment Storing passwords on a home computer
@Iszi: It was just an example to illustrate what I was talking about. I guess one could run ones hashed passwords through reverse lookup and see if they are easily found.

Nope it is not :) I realize that it is easily found using the reverse lookup.

comment How long is a 2048-bit RSA key?
@user27296: You can only have a whole number of digits. So we need at least 616.5 digits. That means that 616 digits are not enough for representing the 2^2048 numbers. You need at least 617 digits. Note that with 617 digits, you can actually represent (write) 10^617 numbers (which is larger than 2^2048).

@this.josh: Yes, I was just wondering about encrypting emails and such, but as mentioned, I don't need serious strong encryption.
