Apple Push Notifications converting p12 to pem files

None of the commands listed on this page worked for me, and yet that is the topped ranked page in Google. What did work for me:

openssl pkcs12 -in apns_certificates.p12  -out apns_certificates.pem -nodes
 
openssl pkcs12 -in apns_key.p12  -out apns_key.pem -nodes
  
chmod 0400 apns_key.pem 

chmod 0400 apns_certificates.pem 
  
openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert apns_certificates.pem -key apns_key.pem
 
cat apns_certificates.pem apns_key.pem   > Peeroapp.pem
