NOTE  You must have the Team Agent or Admin role in App Store Connect to perform any of these tasks  If you are not part of a Team in App Store Connect this probably does not affect you    Sending push notifications to an iOS application requires creating encyption keys  In the past this was a cumbersome process that used SSL keys and certificates  Each SSL certificate was specific to a single iOS application  In 2016 Apple introduced a new authentication key mechanism that is more reliable and easier to use  The new authentication keys are more flexible  simple to maintain and apply to more than on iOS app   Even though it has been years since authentication keys were introduced not every service supports them  FireBase and Amazon Pinpoint support authentication keys  Amazon SNS  Urban Airship  Twilio  and LeanPlum do not  Many open source software packages do not yet support authentication keys   To create the required SSL certificate and export it as PEM file containing public and private keys    Navigate to Certificates  Identifiers  amp  Profiles Create or Edit Your App ID  Enable Push Notifications for the App ID Add an SSL Certificate to the App ID Convert the certificate to PEM format   If you already have the SSL certificate set up for the app in the Apple Developer Center website you can skip ahead to Convert the certificate to PEM format  Keep in mind that you will run into problems if you do not also have the private key that was generated on the Mac that created the signing request that was uploaded to Apple   Read on to see how to avoid losing track of that private key   Navigate to Certificates  Identifiers  amp  Profiles  Xcode does not control certificates or keys for push notifications  To create keys and enable push notifications for an app you must go to the Apple Developer Center website  The Certificates  Identifiers  amp  Profiles section of your account controls App IDs and certificates    To access certificates and profiles you must either have a paid Apple Developer Program membership or be part of a Team that does    Log into the Apple Developer website  Go to Account  then Certificates  Identifiers  amp  Profiles    Create an App ID  Apps that use push notifications can not use wildcard App IDs or provisioning profiles  Each app requires you to set up an App ID record in the Apple Developer Center portal to enable push notifications    Go to App IDs under Identifiers  Search for your app using the bundle identifier  It may already exist  If there is no existing App ID for the app click the     button to create it  Select Explicit App ID in the App ID Suffix section   Enter the bundle identifier for the app  Scroll to the bottom and enable Push Notifications   Click Continue  On the next screen click Register to complete creating the App ID     Enable Push Notifications for the App ID   Go to App IDs under Identifiers  Click on the App ID to see details and scroll to the bottom   Click Edit  In the App ID Settings screen scroll down to Push Notifications  Select the checkbox to enable push notifications      Creating SSL certificates for push notifications is a process of several tasks  Each task has several steps  All of these are necessary to export the keys in P12 or PEM format  Review the steps before proceeding     Add an SSL Certificate to the App ID   Under Development SSL Certificate click Create Certificate  You will need to do this later for production as well  Apple will ask you to create a Certificate Signing Request    To create a certificate you will need to make a Certificate Signing Request  CSR  on a Mac and upload it to Apple    Later if you need to export this certificate as a pkcs12  aka p12  file you will need to use the keychain from the same Mac  When the signing request is created Keychain Access generates a set of keys in the default keychain  These keys are necessary for working with the certificate Apple will create from the signing request      It is a good practice to have a separate keychain specifically for credentials used for development  If you do this make sure this keychain is set to be the default before using Certificate Assistant    Create a Keychain for Development Credentials   Open Keychain Access on your Mac In the File menu select New Keychain    Give your keychain a descriptive name  like  Shared Development  or the name of your application   Create a Certificate Signing Request  CSR   When creating the Certificate Signing Request the Certificate Assistant generates two encryption keys in the default keychain  It is important to make the development keychain the default so the keys are in the right keychain    Open Keychain Access on your Mac  Control-click on the development keychain in the list of keychains Select Make keychain  Shared Development  Default  From the Keychain Access menu select Certificate Assistant  then Request a Certificate From a Certificate Authority    from the sub menu   When the Certificate Assistant appears check Saved To Disk    Enter the email address associated with your Apple Developer Program membership in the User Email Address field  Enter a name for the key in the Common Name field  It is a good idea to use the bundle ID of the app as part of the common name  This makes it easy to tell what certificates and keys belong to which app  Click continue  Certificate Assistant will prompt to save the signing request to a file  In Keychain Access make the  login  keychain the default again    Creating the signing request generated a pair of keys  Before the signing request is uploaded verify that the development keychain has the keys  Their names will be the same as the Common Name used in the signing request     Upload the Certificate Signing Request  CSR   Once the Certicate Signing Request is created upload it to the Apple Developer Center  Apple will create the push notification certificate from the signing request    Upload the Certificate Signing Request Download the certificate Apple has created from the Certificate Signing Request  In Keychain Access select the development keychain from the list of keychains From the File menu select Import Items     Import the certificate file downloaded from Apple   Your development keychain should now show the push certificate with a private key under My Certificates in Keychain Access     At this point the development keychain should be backed up  Many teams keep their push certificates on secure USB drives  commit to internal version control or use a backup solution like Time Machine  The development keychain can be shared between different team members because it does not contain any personal code signing credentials      Keychain files are located in   Library Keychains      Some third party push services require certificates in Privacy Enhanced Mail  PEM  format  while others require Public-Key Cryptography Standards  12  PKCS12 or P12    The certificate downloaded from Apple can be used to export certificates in these formats - but only if you have kept the private key   Convert the certificate to PEM format   In Keychain Access select the development keychain created earlier  Select the push certificate in My Certificates  There should be a private key with it    Download CER push certificate  keychain import complete png  From the File menu select Export Items     In the save panel that opens  select Privacy Enhanced Mail   pem  as the file format  Save the file

I never remember the openssl command needed to create a  pem file  so I made this bash script to simplify the process      bin bash if      -eq 2   then     echo  Signing  1          if   openssl pkcs12 -in  1 -out  2 -nodes -clcerts  then         echo  Error signing certificate       else         echo  Certificate created successfully   2      fi else     if      -gt 2       then         echo  Too many arguments          echo  Syntax   0  lt input p12 gt   lt output pem gt       else         echo  Missing arguments          echo  Syntax   0  lt input p12 gt   lt output pem gt       fi fi   Name it  for example  signpem sh and save it on your user s folder   Users  lt username gt     After creating the file  do a chmod  x signpem sh to make it executable and then you can run     signpem myCertificate p12 myCertificate pem  And myCertificate pem will be created

There is a easiest way to create  Pem file if you have already apns p12 file in your key chain access   Open terminal and enter the below command   For Devlopment openssl pkcs12 -in apns-div-cert p12 -out apns-div-cert pem -nodes -clcerts  For Production openssl pkcs12 -in apns-dist-cert p12 -out apns-dist-cert pem -nodes -clcerts  Rename your P12 file with this name   apns-div-cert p12 otherwise instead of this you need to enter your filename  Thanks

Here is what I did  From blog boxedice com and  iPhone Advanced Projects  chapter 10 byJoe Pezzillo   With the aps developer identity cer in the keychain    Launch Keychain Access from your local Mac and from the login keychain  filter by the Certificates category  You will see an expandable option called    Apple Development Push Services    Right click on    Apple Development Push Services      Export    Apple Development Push Services ID123   Save this as apns-dev-cert p12 file somewhere you can access it  There is no need to enter a password  The next command generates the cert in Mac   s Terminal for PEM format  Privacy Enhanced Mail Security Certificate    openssl pkcs12 -in apns-dev-cert p12 -out apns-dev-cert pem -nodes -clcerts    On the server set the file permission of this unencrypted key by using chmod 400

I would suggest a much more simple solution  Just use Certifire  Certifire is a macOS application that generates Apple Push Notification Certificates with just one click in a couple of seconds   Here are the steps  1  Download the app  2  Log in using your Apple Developer Account credentials  3  Choose the App-ID 4  Click  Generate  button 5  You re done   You will get APN certificates in  pem format as well as in  p12 format   Even more  you will get also combined  pem and  p12 too  key cert   Much more  you will get no-passphrase versions of all these certificates also

This is how I did it on Windows 7  after installing OpenSSL  link goes to the Win32 installer  choose the latest version and not the light version    With this method you only need the  cer file downloaded from Apple   c  OpenSSL-Win32 bin openssl exe x509 -in aps development cer -inform DER -out developer identity pem -outform PEM   this will create a file which you will then need to add your private key too      -----BEGIN PRIVATE KEY-----   MIIEuwIBADANBgkqhk    etc   MIIEuwIBADANBgkqhk    etc   MIIEuwIBADANBgkqhk    etc   MIIEuwIBADANBgkqhk    etc   -----END PRIVATE KEY-----   -----BEGIN CERTIFICATE-----   AwIBAgwIBADAwIBADA    etc   AwIBAgwIBADAwIBADA    etc   AwIBAgwIBADAwIBADA    etc   -----END CERTIFICATE-----    That s it

Steps    Create a CSR Using Key Chain Access Create a P12 Using Key Chain Access using private key APNS App ID and certificate   This gives you three files    The CSR The private key as a p12 file  PushChatKey p12  The SSL certificate  aps development cer   Go to the folder where you downloaded the files  in my case the Desktop     cd   Desktop   Convert the  cer file into a  pem file     openssl x509 -in aps development cer -inform der -out PushChatCert pem  Convert the private key   s  p12 file into a  pem file     openssl pkcs12 -nocerts -out PushChatKey pem -in PushChatKey p12  Enter Import Password   MAC verified OK Enter PEM pass phrase   Verifying - Enter PEM pass phrase   You first need to enter the passphrase for the  p12 file so that openssl can read it  Then you need to enter a new passphrase that will be used to encrypt the PEM file  Again for this tutorial I used    pushchat    as the PEM passphrase  You should choose something more secure  Note  if you don   t enter a PEM passphrase  openssl will not give an error message but the generated  pem file will not have the private key in it   Finally  combine the certificate and key into a single  pem file     cat PushChatCert pem PushChatKey pem  gt  ck pem
