comment Why did customer services say using symbols in a password is insecure?
Why assume that the costumer service person knows why the decision was made? All they know is that the programmers decided to use that policy.

comment Teaching “Secure by Design”
If you have 30 to 45 it's no use to try to teach 5 principles. If you can get the audience to actually apply a single principle that would be success.

comment Is it safe to generate passwords online?
Given that there's good offline tools like KeePass there's no reason to take the risk to use an online tool.

comment Somebody hacked my router and changed my wifi SSID
If you are really using WPA with a password of a decent length, maybe the point failure is somewhere else? Maybe you have a trojan on your computer?

comment Ensure that a file can only be decrypted after a specific date
New altcoins need new features to differentiate themselves from existing coins. This feature alone might not justify a new coin but together with other features it might. Such a feature could be especially valuable if the blockchain get's used as a public store of information. I could imagine to preregister scientific trials on a blockchain. In that case scientists might want to have a time lag till the information get's public but at the same time the information is not valuable enough for an attacker.

To me that doesn't seem "hidden" but openly visible. Is there a way to use fancy math to really hide it?
