S/MIME for iCloud.com emails on iOS (with Comodo certificates)?
I applied for a 2048-bit Comodo certificate for my icloud.com email address. The certificates were delivered in a *.p7s file. They are:
- External CA Root Certificate
- Comodo Certificate
- USERFirst Certificate
- Certificate for my icloud.com email address
I could imported them into my 'login' Keychain on Mac but cannot import them into the 'iCloud' Keychain.
I then exported the certificates one by one into *.cer files and emailed them to myself (@icloud.com) so that I could import them on my iPhone/iPad.
Now I got the certificates under Settings/General/Profiles on iPhone/iPad. Each of them is trusted on iOS.
Message signing/encryption works on my Mac. However if I send myself a message (@icloud.com) encrypted, I cannot read it on my iOS. In the message body it always displays 'This message is encrypted. Install a profie containing your encryption identity to decrypt this message'.
iPhone 4S, iOS 7.0.4
