Friend,
There are lot of tools available on the net to crack the password of the cisco router.
One thing to remember though is you will be able to crack only the level 7 encrypted password and the enable secret.
With the VTY password you will be able to get into the user mode but if you dont remeber the enable secret password you cant get into the privelege mode. Password recovery would be the only option in this case
HTH, rate if it does

Hello,
Besides the afore mentioned tools, which will ONLY decode the "encryption" indicated by 7 in the command, the best bet would be to perform a password recovery. The relevant procedures are described in "Password Recovery Procedures"
http://www.cisco.com/en/US/products/sw/iosswrel/ps1831/products_tech_note09186a00801746e6.shtml
You will need physical access to the router and it involves a reload, i.e. a network outage.
Hope this helps!

Hi Cindy
As mentioned by Naryan in his post you need to use password recovery procedure to reset the enable secret 5 password which is otherwise not possible with any kinda tools as of now..

Hello,
the "5" indicates MD5 encryption, which - to my knowledge - can not be decrypted to date.
So password recovery is your only option.

hi All - we need understand how CISCO strengthen their password, the enable password or password is just hash 7 kind which can be decrypted by any tools but if you use HASH 5 which is nothing but MD5, enable secrete which uses MD5 hash and there is no way you can decrypt. the only way is to follow the password recovery procedure for the respective devices
