Correct format for a PEM

Solution for Correct format for a PEM
is Given Below:

I’m exporting a Private Key from Keychain on Mac, it goes through a bunch of script and I get a file like this.

Bag Attributes
    friendlyName: MY NAME
    localKeyID: AA AA AA AA AA AA AA AA AA AA AA AA AA AA AA AA AA AA AA AA 
Key Attributes: <No Attributes>

As a .PEM file

That seem like too little data for a RSA 2048 Key
