This might sound like a silly question, but someone asked me what PEM stood for, and I just didn't know. I've been using ec2 for a decent while now, and tried googling for it to no avail (lots of results, but none of them conclusively linked back to the ec2 files).
Does anyone happen to know? Maybe also some explanation as to why that naming makes sense? My understanding is that the pem file basically just serves as a private key, but I'm starting to feel that's not quite the case.
It stands for Privacy Enhanced Mail, as explained here.
