Do be aware that some tools require you to have physical access to the target system and, in the same way, bear in mind that, once you have physical access to a system that you are aiming to protect, you can get into all the files that are encrypted or password-protected, so long as you have the right tools for the job.

When you test out some of the password cracking tactics, you must remember that the technique you use will need to be based on the encryption type of the password you want to crack. And, if you are testing out these hacks, you should also keep in mind that some systems can lock associated users out and this can cause a DoS attack on network users.

Password Encryption

Once a password has been created, it is then encrypted with a one-way hash algorithm, which would be seen as an encrypted string. Obviously, these hashes cannot be reversed and this is what makes a password impossible to decrypt. If you are looking to crack passwords stored on a Linux system, there is a little more difficulty. This is because Linux randomizes passwords by adding “salt” or some other random value that makes passwords unique and stops two users from being given the same hash value.

That said, with the right tools, you can launch a number of attacks to try recovering or cracking passwords and here are a few of them:

Dictionary attacks
