The 1password keychain is encrypted, but if I open the keychain file so I can use 1password or to look up info on my keychain on an open unsecure WiFi, could other people see my passwords and secure notes? I believe read Dropbox stores all files encrypted, but that MobileMe does not encrypt them. Is that correct? But since the 1password keychain is already encrypted it's not necessary to have it stored encrypted like on Dropbox??
