// universal_web_notification_sender/src/main/java/info/wearetrying/PushServerVars.java
static final String VAPID_PUBLIC_KEY = "put-the-public-key-here";
static final String VAPID_PRIVATE_KEY = "put-the-private-key-here";



2. Add your subscriptions in `Sender.java` as below.

    ```java
PushSubscription nonSuffariSubscription = new PushSubscription( "subscriptionJson" )
String suffariSubscription = "subscriptionToken";



    

  1. Sample notification should be delivered to your browser when you run Sender.java class.
    2. 



If you need to send notifications to Safari browser, following additional steps are needed.


    

  1. 

    Place your .cer file (i.e apn_developer_identity.cer), .p12 file (i.e. private_dev_key.p12) and .certSigningRequest (i.e CertificateSigningRequest.certSigningRequest) in same directory and execute following commands to create apn_developer_identity.p12.
    

    

    2. 



openssl x509 -in apn_developer_identity.cer -inform DER -out apn_developer_identity.pem -outform PEM}
openssl pkcs12 -nocerts -out private_dev_key.pem -in private_dev_key.p12
openssl rsa -out private_key_noenc.pem -in private_dev_key.pem
openssl pkcs12 -export -in apn_developer_identity.pem -inkey private_key_noenc.pem -certfile CertificateSigningRequest.certSigningRequest -name "apn_developer_identity" -out apn_developer_identity.p12



2. Place your **apn_developer_identity.p12** in **universal_web_notification_sender** project root.
