Interesting, so I guess if you can't use PKCS#12 files with the complete
chain (because Windows doesn't import the CA certs correctly and it's
not possible to correct this programmaticall), you might have to be
prepared to parse two keys in case the CA certificates are not the same.
 local.ca for the CA certificate of the client certificate and
remote.cert (to be compatible with our format) for the CA certificate
required to verify the server certificate.  If they are the same, only
one of these has to be specified (ideally remote.cert so the same file
could be used for Android as well).
