Email cert for S/Mime not working with iOS 6 update

the problem was solved some posts before your long (mostly wrong) firefox-add 🙂

so, i stop emailnotification at thos point.

i just wanted to share my findings on this complex topic because it is hard to find the all the information you need to get email signing and encryption running on iOS.

could you be so kind and be more specific in why my post is"...mostly wrong..." ?

if you do, i would be happy to update ( or even delete! that post ).

what do you mean by " ... i stop emailnotification at thos point" ?

best regards

I have had Comodo certificates working on the Macbook Pro and iPhone5 I have. Recently, after the iOS6 updates on the iPhone were made, I can no longer install a certifcate from a sender. Meaning, if somebody signs an email, and I click the blue icon there, and view certificte, and try to install it, nothing happens. I mean the button depreses to install, but it does not install.

Any ideas woudl be great!

Hello JRC

Your posting helped me sort out my issue (https://discussions.apple.com/thread/5170678); your hint was very noteworthy.

Thank you.

Hey Marsao,

if you've installed the comodo free email cert, dont forget to add this root ca too.

The anwer is elsewhere in the thread but this is what happens on Mavericks and iOS7...

Comodo cert installs in OSX mail easily by saving the P7 cert from Comodo and doubling clicking.

This results in keychain being updated

Then for iOS7, you have to export from Keychain.app the 'login' cert you just added as a .p12 file, and email to yourself. You have to pick a password for this file

You also have to export the Comodo CA Authority cert as a.cer file else the profile is untrusted (but still works).

To do this, search for "Comodo" in Keychain.app and right click onn the blue cert, select export

In iOS, inthe email you sent yourself, you have to click on the .cer file to add Comodo as a trusted profile, enter your device PIN, then done.

Then click on the .p12 file, type in you device PIN, then it asks for password you set on the export, then done

Actually order doesn't matter (I did it other way around)

Both Profile items should appear as 'trusted'.

Then go into advanced settings for for email account, select SMIME ON, then select the profile.

If you send youself an email, you should see the icon on the received email indicating it is digitally signed

I have problems with COMODO certificate on my iPhone/iPad:

I have set both Comodo CA Authority cert and .p12 file and they are both "trusted and green on the iPad!

1. When I send email to myself from the iPad - both on the iPad and Mac (mail.app) the email is received not signed with attachment SMIME.p7s file

2. When I send email to myself from the Mac (mail.app) - both iPad and Mac got the mail right with stamp "sign" and trusted?!

I'm using Gmail configured by Exchange.

How is this possible 😀
