I'll try to sniff the PrincipalKey with Wireshark. Maybe I can find it.
Thanks for your scripts!
They worked great yesterday for me!
Wireshark won't work (connection is encrypted). You have to setup an Apache + PHP Linux server as described in the blog's comments.
Anyway I suspect they haven't changed the PrincipalKey, just increased the MinorKeyRevision so that the PrincipalKey has to be transformed with the MKRevision (in a not yet known way).
