comment Why aren't ransomware deployers arrested?
Use of TOR thwarts tracking you through your network communication from your machine to the bitcoin network. Mixing the coins breaks the chain of transactions from the sender (aka ransomware victim) to the eventual recipient.

comment Why aren't ransomware deployers arrested?
The idea that Bitcoin is anonymous is a myth: this is only partially true... a more accurate statement would be The idea that Bitcoin is anonymous by default is a myth. There are ways to make Bitcoin much more difficult to trace, for example "bitcoin mixers" or ZeroCoin and by using TOR to interact with the bitcoin network.

comment Why would someone “double encrypt”?
I read somewhere that double-encrypting DES actually decreases the security of the encryption, which is why Triple-DES became standard.

comment Could I recover the content of file from its checksum/hash?
@Eumel, not necessarily. His question does not specify the COST of the inversion, just if it were possible. If such a thing were possible but extremely costly, the answer would still be Yes, but it would not necessarily be a practical compression scheme

comment Does every hash value have an inverse value?
I don't understand how you can say that there are a limited number of inputs (no matter how large). Isn't the list of possible inputs to a hash function infinite (since there is no limit to the length of the input)

comment not allowing pasting of bank account number
The fact that their "security feature" was easily circumvented by simply installing a publicly available browser extension seems to point out the "value" of this "feature"

comment Why do we lock our computers?
Hitting WinKey+L or clicking the lock button is next-to-zero cost for you as a user. ... I disagree... the real cost is having to type your password again to get in... not a huge cost but not next-to-zero either

comment How can I prevent my kids from bypassing my computer restrictions?
@Kelley... if someone highly skilled is running up against "rules" in the workplace, then it's probably because the "rules" are interfering with their ability to do the job (e.g. not providing or allowing the use of the best tools for the job)... these places are usually not the most "high paying" anyway... leave it for a saner and more high paying one

comment Digital Certificate deployment: using two certs for each user?
I don't see how an admin can circumvent a smart card... Isn't it the case that the smart card is the only place the private key is stored? If the admin does not have access to the card, they have no way of generating a signature. No amount of "manipulating the application" will generate a fake signature (assuming the public key remains genuine).
