Keychain is encrypted on our Mac's, but when it reaches MobileMe's servers are they still encrypted? Mail, I don't believe is encrypted on our Mac's (unless you use FileVault?), are they sitting on MobileMe's servers as encrypted? I know while sync'ing and traveling through the internet MobileMe data is encrypted, but does any know the type of encryption? 256 AES? which is the best, AFAIK. And just to verify, all MobileMe data is encrypted in transit including Cal data, bookmark data? Ok, thanks if you can help. I chat with a MM rep and he looked around for info, but didn't know the answers.
