ios with NO PAYLOAD ENCRYPTION

[Leftz]

Hello, we can find the below two ios in Cisco download web site. The second one is with "NO PAYLOAD ENCRYPTION".  When we upgrade ios, what different additional action do we need to do for first one or second one as it notes "NO PAYLOAD ENCRYPTION"? Thank you.

Universal images with the universalk9_npe" designation in the image name: The strong enforcement of encryption capabilities provided by Cisco Software Activation satisfies requirements for the export of encryption capabilities. However, some countries have import requirements that require that the platform does not support any strong crypto functionality such as payload cryptography. To satisfy the import requirements of those countries, the `npe' universal image does not support any strong payload encryption. This image supports security features like Zone-Based Firewall, Intrusion Prevention through SECNPE-K9 license.

So you would use this image if you were in a country that has import restrictions on strong crypto.
