IPSEC enabled?

[sarenos2006]

I have 2 Cisco 2651 and I'm trying to configure a IPsec tunnel between them, but when I try to use the command crypto in the configure terminal doesn´t exists, Is not possible by default the configuration of IPsec in all the routers? Do I need a license or something like that? How can I know if my router support IPsec? I have Cisco IOS 12.4
