Can someone tell me a version of IOS that supports the crypto command so I can start using SSH? It is an 1841 router. I'm currently using 12.4(1c) and it doesn't support the crypto or ssh commands. <br />
<br />
Thank you,<br />

Cisco IOS version that supports crypto

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
