First, shorter passwords of four to six characters were easy for Terahash to crack regardless of the algorithm. There are two important takeaways from this chart. Gradations of orange and red represent passwords that take a year or more to crack.

The other columnsвЂ™ color-coding represents the ease with which a hashed password in each algorithm can be cracked, based upon its original length.В That sea of turquoise blue represents shorter passwords of four to eight characters, which can be cracked вЂњInstantlyвЂќ or in up to an hour, depending on the hash algorithm used.В The dark-green areas represent passwords that can take up to a day to be cracked, while bright-green ones take up to a week, and so on. The other is the length of the original password. This chart illustrates how just adding a few more characters to a password can make the time necessary to crack it almost impossibly long, even with TerahashвЂ™s powerful GPU cluster at your disposal.Д«ut the algorithm is only part of the challenge. The topmost algorithm, NTLM, proved the fastest to crack overall, along with many other algorithms coded dark red while the Bitcoin/Litecoin algorithm at bottom took the longest, and is coded yellow-green. The color immediately adjacent indicates how quickly a password hashed in each algorithm can be cracked by TerahashвЂ™s password-cracking technology. The chart lists major hashing algorithms on the left.

The graphic shown below, put together in 2018 by professional password-cracking company Terahash, shows both how impossibly easy-and how incredibly difficult-password-cracking can be. So does that mean a four-character password is safe? Absolutely not. (Foreign-language keyboards can affect this, and some sites might require only a subset of the available special characters.) Based on a list of 96 characters, even a four-character password like t7G(В would theoretically require up to 84,934,656 (96 to the 4th power) separate guesses. Adding the numerals 0-9 brings you to 62 possibilities, and special characters lift the total to 96. A single-character password already represents 26 possibilities-or 52, when you add upper-case letters.

(HereвЂ™s how to tell if your password has been stolen.) How hard is it to crack a password?Д¬racking a password can get enormously complex, very quickly. Your hashed passwordвЂ™s enemies are time, computing power, and smart guesses.

In this scenario, all the cracker really needs to know-or to guess-is the algorithm used to hash the passwords, then apply the PCвЂ™s enormous computing power to make billions of guesses per second to crack a password. Once those hashed passwords were published, there wasnвЂ™t any way of stopping those with access to them from downloading them to their own PC, then trying to crack them without any of the rate controls enforced by a live website. Take this example: In 2019, a massive trove of 2.19 billion email addresses/usernames and passwords leaked to the web, part of the Collections breach. Guess wrong too many times, and the site will probably flag the account or your IP address as a potential hacker, and either limit or block your login attempts entirely.ДЄfter a password breach, however, all bets are off. A smartly designed website will have some form of control built in. You simply canвЂ™t try to log in to Amazon, however, pretend youвЂ™re Bill Gates, and guess and guess and guess passwords until you get lucky. Thus, the password maverickВ becomes 55f9c405bd87ba23896f34011ffce8da.ДЄ large institutional website, like this one, is typically secured with measures preventing users from trying password after password in an attempt to break into user accounts. Just type the word to be hashed into the box, and click Generate. In this case, we hashed the password fred. (We would recommend not hashing a password you actually plan to use, for securityвЂ™s sake.) MD5 is an older algorithm thatвЂ™s considered unsafe for a number of reasons, but itвЂ™s still useful for demonstrating how password hashing and cracking work. For an MD5 hash, all you need to do is visit a site like and hash an example word.

It might even take that first hash and hash it again, or add whatвЂ™s known as a вЂњsaltвЂќ-a series of additional characters that makes your password even harder to tease out.Д¬reating an example hash is easy. The site wonвЂ™t advertise which hashing algorithm it uses, as that would only make life easier for crackers.

Instead, it will use whatвЂ™s known as a hashing algorithm-common ones include MD5, SHA2, or SHA3, but there are many more-to take your password and turn it into aВ вЂњhash,вЂќ a string of seemingly random numbers and letters. To deter crackers, a responsible website wonвЂ™t store a password in its original form, in whatвЂ™s known as plaintext.
