Pyapn Right Way To Create Pem Files

I know this might be due to lack of better knowledge, but I seem not to be able to get this running. What is the right way as of today how to create the correct certificates / pem

Solution 1:

Ok, after some googling and trial and errors I finally have gotten through to get a send confirmation Sent push message to APNS gateway from PyAPNs.

Here are the steps how I had to adjust my pem files.

openssl pkcs12 -in cert.p12 -out cert.pem -clcerts -nokeys 
openssl pkcs12 -in key.p12  -out key.pem -nocerts  
openssl rsa -in key.pem -out keyNoPasswd.pem

cat keyNoPasswd.pem > mergedPushCertificate.pem
cat cert.pem >> mergedPushCertificate.pem

Use mergedPushCertificate.pem as certificate and key in PyAPNs. Based on https://github.com/project-imas/mdm-server/issues/6
