How can I re-download the pem file in AWS EC2?
No, you cannot download .pem file again. You can download the .pem file ONLY once and that is when you create a new key-pair.
You can not download such security key files more than once.
You can reuse them for multiple instances.
The best thing you can do is:
- Download it
- store it at
S3(Of course in a private access bucket.)
