Creating .pem file for APNS?

Question

How do I create a .pem file to be stored in the hosting server for APN payload data?

Answer 1

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  "
    else
        echo "Missing arguments"
        echo "Syntax: $0  "
    fi
fi

Name it, for example, signpem.sh and save it on your user's folder (/Users/?). 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.
