need more detail about the "keys"

[pabmas]

hi

I saw there are four sentences needed to be translated to TCH but...
what the "key" represents in the following sentence?
key binding on keyboard or private key in encryption or flashfxp license key or something else?

&Mark this key as exportable.
This will allow you to back up or transport your keys at a later time.

This is referring to the private encryption key when importing a x509 certificate or SSH key pair.
