![]() ![]() ![]() Thankfully, you aren’t on your own – there are some tools to help you: Password security checkers. These wordlists are surprisingly effective, as a lot of people use generic or common passwords. It’s crucial to have a password that isn’t on any such list. Hackers will run the password list on sites hoping to get a match. In other words, a wordlist keeps passwords like “Susie1202” and “Password12”. Wordlists can run to millions of entries and are used by hackers to make educated guesses at passwords rather than the slower method of trying all possible combinations starting from “aaaaaa”. A wordlist is a list of known and generally common passwords. Websites or downloadable software could take the password that you’re trying to test and add it to a wordlist. It is highly unlikely it will ever be cracked unless your password is singled out and targeted by multiple systems.The first rule of testing the strength of a password is to be extremely careful when using online tools to test your passwords. On a supercomputer, it would take 81,615,877,245 millennia to crack. “i have a very strong password” = 107.4 bits of entropyġ07.4 bits of entropy = 5,141,800,300,000,000,000 millennia for the average Joe password cracker to break.Or on a supercomputer about 105 days, in theory. “mygmailpassword” = 58.9 bits of entropyĥ8.9 bits of entropy = 18,267,344 years for the average Joe password crack to break.That translates to less than a minute for almost any cracking expert out there to break in! ![]() It’s just a simple box, and when you type in the password, it will tell you its strength, the character set, and its level of entropy.ģ5.5 bits of entropy = 398 days for the average Joe to crack, but only 0.5 seconds for a supercomputer to break. Of the available tools, the Cygnius Password Strength Test is my favorite. But, if the website ever gets hacked then its password hashes can be easily run through any offline cracking system that the hackers have set up. Keep in mind that while these passwords are stored on a web server, they are usually protected by a maximum number of password attempts over a certain amount of time. The typical website uses SHA1, which a supercomputer could crack at a rate of 63 billion guesses per second. But, the guess rate is significantly slowed down depending upon which encryption algorithm is used. However, if we speed that up to crazy supercomputer levels ( like this guy who built a 25-GPU machine that can do 350 billion guesses per second), it becomes a lot quicker.Divide # of guesses needed by guesses-per-second and you have the seconds of time required to crack the password, just divide according to days/hours/minutes.Any average Joe can install password-cracker software and make about 1000 guesses per second.2^(the level of entropy) = number of guesses needed to crack.Please note that this is a very, very simplified explanation but here it goes. its amount of entropy, there is a very simplified formula to follow. To understand the basics of how long a password would take to crack vs. Or, in other words, the higher the entropy, the more secure your password is. What is Password Entropy?Įntropy is the level of unpredictability for a password. That being said, I strongly suggest you don’t use your exact real password with them. Most online password testing sites claim they will never record any data you enter into the password testers. ![]()
