Cisco 1841 DES/3DES encryption

[network_user]

Hello,

       I have a new Cisco 1841 and when I do a sh ver it does not show me any licenses des/3des attached to it. I would like to know, how can I enable des/3des encryption on this router. I read that it has onboard des/3des encryption and I can enable it using an optional Cisco software. However I am not sure what software to use to enable the encryption. Could someone guide me through this?

Thank you.

Hi,

You need to have the following IOS or later on the router in order to enable crypto c1841-advsecurityk9-mz.124-24.T3.bin

Once you have the baove IOS then you can define the crypto policy in which you can mention the encryption algorithms like below...

crypto isakmp policy 14
encr 3des
authentication pre-share
group 2

Hope this clear you.
