Password Cracking Tools
Password cracking and the associated password cracker tools are often the area of information security and hacking that people get most excited about, oh wow I can hack email passwords? We get emails pretty much every day asking how to crack someone's Facebook password, or retrieve website credentials etc.
What is Password Cracking?
As commonly defined:
In cryptanalysis and computer security, password cracking is the process of recovering passwords from data that have been stored in or transmitted by a computer system. A common approach (brute-force attack) is to try guesses repeatedly for the password and check them against an available cryptographic hash of the password.
The purpose of password cracking might be to help a user recover a forgotten password (installing an entirely new password is less of a security risk, but it involves System Administration privileges), to gain unauthorized access to a system, or as a preventive measure by system administrators to check for easily crackable passwords. On a file-by-file basis, password cracking is utilized to gain access to digital evidence for which a judge has allowed access but the particular file's access is restricted.
