It takes five days to crack a nine-character password, four months to crack a ten-character password, and ten years to crack an eleven-character password. If you increase the number of characters to 12, you'll have 200 years of security—not bad for a single letter.
A computer can calculate up to 2128 options per second. This means that it would take about 200 years to try all combinations of letters and numbers of length 12 or less.
This is why passwords with more than eight characters are recommended to provide better security. Also, it's important not to use easily guessed information such as your first name or child's name. It's best if you use a unique phrase instead.
If your password is 12 characters lengthy and contains numbers, upper and lowercase letters, and symbols, it will take a hacker 34,000 years to crack it. The application claims that the shorter your password, the simpler it will be guessed. Even if you employ every possible permutation It will be cracked in hours if you use eight characters.
That means that your password should be at least nine characters long if you don't want hackers cracking it anytime soon!
The website says that its calculations are based on average computer performance. So obviously if you have a supercomputer at your disposal, you can crank out passwords faster than this app allows users to type.
However, just like most other password guessing apps, this one isn't designed for supercomputers or high-end laptops. It's more geared towards regular desktop computers which can handle such tasks as password hacking efficiently.
You should also note that although this app claims that its formula for calculating how long it would take to hack a password is scientific, there are certain factors that may come into play when trying to break passwords. For example, hackers can use tools to assist them with their efforts. Such tools can work in the background while they focus on other things so they can try many combinations quickly.
In addition, hackers may be able to use information about our habits and patterns to guess our passwords.
3.18 days are equal to 275243 seconds. That's true, a password made up entirely of lowercase alphabetical characters can be cracked in 3.18 seconds. A password containing only numbers would take more than 26 years to decode.
A password with both upper and lowercase letters requires more time. It can be calculated that a random character string of length 20 including both uppercase and lowercase letters could be decoded in about 3.5 minutes. This means that a password with this strength should be able to be decrypted within the lifetime of most computers.
Cracking passwords is difficult because there are so many possible combinations. Even if you choose extremely strong passwords, like "qwertyuiopasdfghjklzxcvbnm", it will still be easy for someone to guess them if they know how many characters your password is and what characters are used in it. Crackers use special programs called password databases which contain millions of entries like these: qwertyuipassword". When a user enters a password into a website, it is hashed using one of several different algorithms. The resulting string of characters is then saved in the database along with information about how long it took to generate it.
According to a recent research done by security firm Hive Systems, passwords less than 10 characters long may frequently be hacked in under an hour (and this time is shortening as computer hardware processing power improves); passwords at least 12 characters long, even with simply lowercase letters. The longer your password, the better it protects you against hackers.
Creating an endlessly difficult password According to iFusion Labs' estimations, a seven-character password made up of just lowercase letters might be broken in around two hours and twenty minutes. But a similar password containing both upper- and lowercase letters would take more than one hundred years to break! A number-based password could never be cracked using conventional means because there are too many possible combinations. A password is considered impossible to crack if no computer can solve it within a reasonable amount of time.
Preventing passwords being cracked If you can't come up with a good password, there are tools available that will generate them for you. These include Password Generators such as the popular MyPasswordManager (free) which will create random characters and put them into a list for you to choose from. Of course, using these types of tools makes your password space much larger, so you should pick very unique words or phrases to avoid making your password list easy to guess.
Passwords cannot be easily remembered either by humans or computers, so they need to be stored somewhere for others not to see them. Most people store their passwords in a plain text file on their hard drive accessible to anyone who gains access to their computer. This is why it's important to use different passwords for different sites and to change them regularly.
