We have passwords for emails, databases, computer systems, servers, bank accounts, and virtually everything that we want to protect. Passwords are in general the keys to get access into a system or an account.

In general, people tend to set passwords that are easy to remember, such as their date of birth, names of family members, mobile numbers, etc. This is what makes the passwords weak and prone to easy hacking.

One should always take care to have a strong password to defend their accounts from potential hackers. A strong password has the following attributes −

• Contains at least 8 characters.

• A mix of letters, numbers, and special characters.

• A combination of small and capital letters.

Password cracking is the most enjoyable hacks for bad guys. It increases the sense of exploration and useful in figuring out the password. The password cracking may not have a burning desire to hack the password of everyone. The actual password of the user is not stored in the well-designed password-based authentication system. Due to this, the hacker can easily access to user's account on the system. Instead of a password, a password hash is stored by the authentication system. The hash function is a one-way design. It means it is difficult for a hacker to find the input that produces a given output. The comparison of the real password and the comparison of two password hash are almost good. The hash function compares the stored password and the hash password provided by the user. In the password cracking process, we extract the password from an associated passwords hash.
