While tools like the one above are all well and good, your Cisco router will do exactly the same for you, to demonstrate, paste the following into the tool above.

So whats the point of these type 7 passwords? The passwords in my config are in clear text? If you want to convert your config to display them as 7 you need to enter the service password-encryption command;. To crack it, we have to again first convert it to the following john friendly format and save it in a file:.

From the above screenshot we can see that the average speed is around thousand password attempts per second. To crack it, we can keep using the same john friendly format.

Then we can crack it like this using a dictionary, for example:. Much better than john in our case. This password type is a proper implementation of the failed password type 4. Essentially it is 20, iterations of SHA and this makes it much harder to crack in comparison with the previous password types. John the Ripper recognizes this password type as pbkdf2-hmac-sha From the above screenshot we can see that the average speed is around 1, password attempts per second.

Not much. From the above screenshot we can see that the average speed is around 11, password attempts per second. This password type uses Scrypt algorithm. This is due to the fact that Scrypt requires large amount of memory to perform its function. John the Ripper recognizes this password type as scrypt. Note that we have to provide --force parameter since the hash-mode is marked as unstable for our particular device. Not much either. John the Ripper contains very useful ruleset for generating passwords called KoreLogic.

This ruleset originated in DEFCON contest and it is a great way of generating passwords from patterns or when traditional dictionary attack fails. Although there has been some efforts to convert the aforementioned KoreLogic rules into Hashcat, the result is only partial.

Fortunately, we can chain together John the Ripper with Hashcat to make it use KoreLogic rules in full. Simply generate the passwords using John the Ripper on the stdout and feed them into Hashcat using pipe like this:.
