no crypto commands on cisco switch, can't enable ssh

I was trying to enable ssh on a switch but the crypto commands were not present. The was because the image that was running on the switch didn't have cryptographic services installed. Some countries don't allow cryptographic services and omitting it is also done to make the switch cheaper.

If you do a show version you will see something like the following
System image file is "flash:/c2970-lanbase-mz.122-25.SED/c2970-lanbase-mz.122-25.SED.bin"
We would want to see K9  in the image name not lanbase

You can download and apply the K9 image from Cisco provided you have the correct license (and even if you haven't purchased the license, but that's not legal)

As a temporary workaround, I connected the console cable to a server that I have access to and connected that way.
