That is the password-passcode system too... better use variety, spaces, different numbers and letters

I like the picture time and space spiral. Hacking need a lot time, patient, and skill.

Please post more on hacking. Always so interested on hacking and testing.

Encryption is generally about increasing the amount of time it would take an adversary to access some specific information. The point being that human beings aren't expected to keep information a secret forever, but merely to keep it secret long enough that it doesn't jeopardize the reason it is being kept secret.

So if you are talking about something classified, the human beings who have the burden of keeping their knowledge secret are psychologically tasked with a 24/7 365 job, which costs in terms of **"emotional labor"**, which usually isn't even calculated in the market. 

The conclusion of all of this? No sane person should want a security clearance thinking it's cool to have that kind of responsibility. No sane person should want to have to manage private keys, whether for a Bitcoin wallet, or whatever, because there is a definite psychological cost to doing so and that psychological cost matters.

If we are talking about Bitcoin, that psychological cost could be one of the reasons Bitcoin isn't going to be popular. If we are talking about SAFE Network it's again a situation where the psychological burden for most people is too heavy to be worth whatever privacy benefit they get. It's also something Steemit is going to have to manage which is that the user experience has to take precedent over other aspects. You can make it secure but there comes a point of diminishing returns, where the information being kept secure is no longer worth the burden to the average person.

For this reason, experts and professional companies exist to manage private keys and other exceptionally hard to secure information.

I saw the title and thought you had finally done it... conquered time travel. But I guess you don't have to with you outlook of now.

Usually to generate a "random" key, seeds it with the time it was created.

Here is a great example of that with the guy who wrote the myspace worm:

in PHP: part of the session key is seeded with time, that gives you a small part of the giant session key, but possible to brute force the rest if you know say... when the server issued the session, and their IP address.

I would assume this is fixed by now, but great example of "hacking time".

I wonder how it it takes to become a skilled hacker
