I am getting so tired of this ;-).
I'm sure that MCS can export to pkcs12 format. Simply use the exported file
as your keystore. For an Apache example to work from, look at the Tomcat 5
ssl-howto. Of course, if you get a recipe for doing this with MCS, please
post it so that I can include
Try selecting Base64 encoded certificate instead of DER encoded. Also
from what I understand keytool will only import certificates with a key
size under 4096 bits. If your certificate's public key is 4096 bits or
bigger you won't be able to import into your keystore with keytool.
