To get a certificate, you need to generate a Certificate Signing Request with Keychain Access and send it to Apple. This will create a public/private key for you if you don't have one already. Apple will then verify the information, and create a certificate for you. As long as you still have access to the mac which was used to generate the original distribution certificate it's very simple. Just use that mac's Keychain Access application to export both the certificate and the private key. Select both using shift or command and right click to export to a.p12 file. You could add a k Sec Public Key Attrs attribute to the attributes dictionary, specifying a distinct tag and keychain storage for the public key. However, it’s typically easier to store only the private key and then generate the public key from it when needed. That way you don’t need to keep track of another tag or clutter your keychain.

- Due to Apple only allowing one member of an enterprise account to hold the role of Team Agent and that user having their certificate associated with that accounts distribution certificate, if you want to have multiple machines capable of signing a build with that distribution certificate we need a way to share that certificate's private key.
- All SSL Certificates require a private key to work. The private key is a separate file that’s used in the encryption/decryption of data sent between your server and the connecting clients. A private key is created by you—the certificate owner—when you request your certificate with a Certificate Signing Request (CSR).
You'll need two kinds of files to sign your app: Certificates and Provisioning Profiles.
Generate a Code Signing Certificate¶
The certificates - development or distribution - are the guarantee that you, the named developer, built this code, that you are a member of the developer program, and that Apple have issued you with a certificate to do so.

Generate a Code Signing Certificate using Xcode¶
First you have to add your Apple ID to Accounts preferences in Xcode. If you are already done with this, you can skip to step 6.
- Start Xcode
- Select Xcode > Preferences from the navigation bar.
- At the top of the window select
Accounts
. - Click on the
+
on the lower left corner and selectAdd Apple ID...
- A dialog will appear. Add your Apple ID and your password, then select
Sign in
. If you don't have an account you can create your Apple ID by selectingCreate Apple ID
. - Select your Apple ID and your team from the right side bar, then click on
View Details...
. - A dialog will appear where you will see your code signing identities and the provisioning profiles.
- Under the signing identities locate the
iOS Development
andiOS Distribution
profiles. If you have not created them you will see aCreate
button next to them. Simply select it and Xcode will issue and download your code signing identities for you.
Warning
If you already have Code Signing Identities issued, you will see a
Reset
button next to them. You can issue new certificates with it, that Xcode will generate and download, however note that this will invalidate your previous certificate, so only do this if you've lost those files or if you know what you are doing!Generate a Code Signing Certificate manually¶
- Open your
Keychain Access
app on macOS. - Select
Keychain Access
>Certificate Assistant
>Request a Certificate From a Certificate Authority...
- Fill in the
User's Email Address
and theCommon Name
and selectSaved to Disk
. Click onContinue
and save the generatedcertSigningRequest
file locally. - Go to https://developer.apple.com and log in to your account.
- Select
Certificates, IDs & Profiles
from the left sidebar. - Go to
Certificates
and click on the+
button on the top right corner. - Select
iOS App Development
and click Continue. - On the next page you see the instructions for creating the
certSigningRequest
file. Click continue. - Upload the created
certSigningRequest
to the form and click continue. It will generate your code signing certificate for you. - Download the certificate and double click to install it. Once installed it will be added to your
Keychain Access
app.
Generate a Provisioning Profile¶
Generate Private Key From Certificate Ios 8
Provisioning is the process of preparing and configuring an app to launch on devices and to use app services. Development Provisioning Profiles holds the device identifiers ( UUID ) that is eligible to run your app. Distribution Provisioning Profiles can include App Store profiles, that lets you distribute your app to the App Store and Ad-hoc profiles are good for distributing to your testers.
Generate a Provisioning Profile with Xcode¶
Xcode will automatically generate an App ID for your project, that matches your unique bundle ID for your project. An App ID is used to identify one or more of your apps. It can be an explicit App ID that only matches one unique bundle identifier or a wildcard App ID that can match multiple ones.
Xcode will also create a Team Provisioning Profile for your project automatically, so you can start deploying to your device automatically.
If you hit any issues you should make sure that the device is eligible, for example if the device doesn't match the deployment target you will get an error.
Also make sure that your app is connected to the correct Team.
- Select your project file from Xcode's project navigator
- Go to the
Signing
section and under theTeam
select your correct team.
Note
If you hit any issues and can't resolve it move to the manual step and set up Provisioning Profiles following the documentation.
Note
To setup a distribution Provisioning Profile, go ahead with the manual setup.

Download a Provisioning Profile with Xcode¶
If you have already created the Provisioning Profile, you can do the following.
- Start Xcode
- Select Xcode > Preferences from the navigation bar.
- At the top of the window select
Accounts
. - Select your Apple ID and your team, then select
Download Manual Profiles
. - Go to
~/Library/MobileDevice/Provisioning Profiles/
and your profiles should be there.

Setup an App ID¶
- If you haven't already created an App ID for your project, go to https://developer.apple.com and log in.
- Select Certificates, Identifiers & Profiles from the left sidebar
- Navigate to Identifiers > App IDs
- In the
App ID Description
add a recognizable name for your App ID - Select

Using the iOS keychain to store your private key has the added security advantage of leveraging on the hardware-backed keystores that exist on many iOS devices, allowing the key to be protected by the iOS-level device password, and preventing key compromise even if the device is rooted.
If you already have your client certificate and private key bundled into a PKCS#12 file (extension .p12 or .pfx), you can import it into the app private section of the iOS Keychain using Mail, Safari or iTunes. Note sure that the file extension has to be changed to .ovpn12 for the file to be picked up by the OpenVPN Connect App (and not by iOS).
![Generate Private Key From Certificate Ios Generate Private Key From Certificate Ios](/uploads/1/2/5/8/125869745/767163030.png)
Note that on iOS, when you import a PKCS#12 file into the Keychain, only the client certificate and private key are imported. The CA (certificate authority) certificates are NOT imported (unless you manually extract the CA certificates and import them separately, one-at-a-time). Therefore, the CA list must be given in the profile using the ca directive. If you already have a PKCS#12 file, the CA list may be extracted from the file using this openssl command, where the CA certs in client.p12 are written to ca.crt:
Then add a reference to ca.crt to your profile:
or paste the contents of ca.crt directly into your profile:
If you don't have a PKCS#12 file, you can convert your certificate and key files into PKCS#12 form using this opensslcommand (where cert, key, and ca are your client certificate, client key, and root CA files).
Then import the client.ovpn12 file from the previous step into the app using Mail or Safari.
Once this is done, remove the cert and key directives from your .ovpn file and re-import it, making sure that the cadirective remains. Once imported, any profile that lacks cert and key directives will cause a Certificate row to appear on the main view, allowing the profile to be linked with an Identity from the iOS Keychain (on iOS, an Identity refers to a certificate/private-key pair that was previously imported using a PKCS#12 file). Touch the Certificate row and select the MyClient certificate. At this point, you should be able to connect normally.
Note that the iOS Keychain is accessible by the app only after the user has unlocked the device at least once after restart. For this reason a profile requiring a certificate stored in the Keychain to connect won't be able to do so automatically after restart.
