Encrypt passwords on Cisco routers and switches

We have seen how to set passwords on cisco switches or routers here. Of course setting passwords does add to the security of the device but there is small problem. The password is stored in plain text.  Anyone who gets access to the switch can easily see all the passwords by typing command “show running-config or show startup-config”. Today we will see how to encrypt passwords on Cisco routers and switches.

Encrypting passwords can further enhance the security of the device. Privileged password can be encrypted by using the command “enable secret” instead of “enable password”. This command should be set from privileged global configuration mode.

Lets see what can we see  when we use the command “show running-config”.

We can see that the password we set has been encrypted. but what about other passwords. The  console, auxiliary and vty lines passwords cannot be encrypted even if we use “enable secret” command. To encrypt those passwords, we have to use another command “service password-encryption” as shown below.

This command will encrypt all the passwords stored in plain text on the device. Want to learn advanced practical hacking? Have a look at our Hacking Magazine. Just don’t trust our word. Download your FREE COPY using discount code fq47p4tq

  1. If you want your password not to be seen in the configuration of a router than enable secret password is the best option, because when someone views the running configuration they will see and know your enable password, but in the case of enable secret password they will only see the encrypted string.
