![]() ![]() This has become such common practice that there are websites that list common passwords alongside their (calculated) hashed value. ![]() When faced with a file full of hashed passwords, a brute force attack can be used, trying every combination of characters for a range of password lengths. This process is repeated each time you login.įor example, the password “Pa$$w0rd” is given the value “02726d40f378e716981c4321d60ba3a325ed6a4c” when calculated using the SHA1 hashing algorithm. When you try to login, the password you enter is hashed using the same process and compared to the version stored on the site.

Website passwords are usually stored in a protected manner using a mathematical algorithm called hashing. ![]() You can purchase almost 600 million passwords online for just AU$14!
