How to Create KeyPair for EC2 on Amazon Web Service(AWS).

A key pair, consisting of a private key and a public key, is a set of security credentials that you use to prove your identity when connecting to an instance. Amazon EC2 stores the public key, and you store the private key. You use the private key, instead of a password, to securely access your instances.

PEM (Privacy Enhanced Mail) is a base64 container format for encoding keys and certificates. . pem download from AWS when you created your key-pair. This is only a one time download and you cannot download it again.

PPK(Putty Private Key) is a windows ssh client, it does not support . pem format.
