IOS – Unable to import S/MIME certificate and key into the iPhone (iOS7)

certificateios

I tried to generate a S/MIME certificate from comodo.com. On my Mac it perfectly works. But I am unable to use it on iOS 7. This is what I did:

  • generate certificate on Mac
  • export certificate and private key in p12 format from keychain
  • sent the p12 and the Comodo cert (COMODO Client Authentication and Secure Email CA.cer) via email to iphone
  • import both certificates
  • enable S/MIME in email client on iPhone

When I look into my Profiles (General > Profiles) I see the comodo certificate as TRUSTED (1) as well as my private cert (2) . But when I look into the S/MIME settings from the email account on iPhone it is NOT TRUSTED (3).



My emails got not signed / encrypted then.

What am I doing wrong? I am lost.

Surprisingly I had a look into my certificate in the mail accounts section. It was untrusted. I then got into the section of profiles and had a look into the imported profile. It was trusted.

Then I went back to the certificate in the mail account section and it was trusted!

This seems all quite buggy, Apple.
