Even if you are Jack Dorsey.A simple, intuitive web app for analysing and decoding data without having to deal with complex tools or programming languages. Whilst private keys and wallet seeds may be virtually uncrackable by brute force, the weakest link in your bitcoin security is always you. Whereas ‘ ’ would take around 14 years to brute force. ‘Password’ is crackable in about a fifth of a millisecond (or five weeks if the hacker doesn’t use word lists. 12 random letters would take 2 centuries to crack with today’s technology.Īnother way to improve security is to use a combination of upper and lower-case letters, numbers, and special characters. So essentially, the longer your password is, the better. Adding a letter tales it to 5 hours and we go up exponentially from there. In terms of passwords, a string of 7 random letters would take less than half a millisecond to crack. But this sort of security relies heavily on preventing an attacker from spamming every option at once. The app allows you to go back in time and find that in 1992 it would have taken a bit longer, at nearly 3 and a half minutes. Assuming you could have infinite tries before being locked out. The bad news is that a 4-digit PIN would take 5 milliseconds to crack.

Hardware wallets may be secured with a simple 4-digit PIN. Software wallets might be on a phone or computer, hidden only behind a passcode or word. Our Bitcoin wallet seeds might well be written down somewhere, but our wallets are generally accessible through far less onerous defences. Okay, So What About Something More Tangible? And, testing a random key from an empty wallet I set up for the purposes of this article, we still get an estimate of an infinite amount of time required to crack it.
