client.p12 is totally unreadable.
Thanks, Eddie! I also dive-in into my Kindle DX. I can confirmed that /var/local/java/prefs/certs is now consist "client.p12". This seemed to be the `private' certificate of the Kindle. When it runs in my Windows PC, "client.p12" trigger a window that I never saw before. It looks like a wizard to create a certificate. So yes, Amazon firmware 2.5.8 has at least one bug. It delete the `private key' from the device if it is factory reset.

About the `private' and `general' certificate, @knc1 you are right! On creating an image backup, I have tested Yifanlu's tool works for Kindle DX. I will make an image backup. Just in case days like these happen again.
