Apple Developer Program membership is required to request, download, and use signing certificates issued by Apple. For developers part of a team enrolled as an organization, you must also be the account holder or an admin to request distribution certificates used for submitting apps to the App Store.

Using Certificates

In most cases, Xcode is the preferred method to request and install digital certificates for iOS and macOS. However, to request certificates for the Apple Push Notification service, Apple Wallet, Mobile Device Management (MDM), and Safari extensions, you will need to request and download them from Certificates, Identifiers & Profiles in your account on the developer website.

Certificate Private Key File

Then navigate to the certificate file (the.cer file) you obtained from Apple. Select the Keys category in Keychain Access. Select the private key associated with your iPhone Development Certificate. The private key is identified by the iPhone Developer: public certificate that is paired with it. Select File Export Items.

It's asking for the 'public key certificate'.is that what we get from the MDM Server Box? When creating an Apple Pay certificate signing request, Apple specifies that you need to use a 256 bit elliptic curve key pair. To generate both the private key and the CSR using the openssl command line utility, do the following. Where private.key is your existing private RSA key, certificate.crt is your existing certificate and MyPKCS12.p12 is the name of the file to create. This file can then be imported into your keychain. If you need your key for SSH access (SFTP, SCP or similar), it doesn't have to be in your keychain. Now go back to the Keychain Access tool, select the new Private Key that has just been created in the Keys section and choose File Export from the menu to save the private key to disk. You will be asked to enter a passphrase as you save the file. Our private key file was saved as deltaCrunch.p12. Creating an App ID and SSL Certificate. Where private.key is your existing private RSA key, certificate.crt is your existing certificate and MyPKCS12.p12 is the name of the file to create. This file can then be imported into your keychain. If you need your key for SSH access (SFTP, SCP or similar), it doesn't have to be in your keychain.

FAQs

Certificate Private Key

I received an error message saying, 'Xcode could not find a valid private-key/certificate pair for this profile in your keychain.'

This error message indicates that your system’s Keychain is missing either the public or private key for the certificate you are using to sign your application.

This often happens when you are trying to sign and build your application from a different system than the one you originally used to request your code signing certificate. It can also happen if your certificate has expired or has been revoked. Ensure that your app’s provisioning profile contains a valid code signing certificate, and that your system’s Keychain contains that certificate, the private key originally used to generate that certificate, and the WWDR Intermediate Certificate.

For instructions on how to resolve this error, review the Code Signing support page.
