-- Creates a 2048-bit RSA key pair with the specified name. Amazon EC2 stores the public key and displays the private key for you to save to a file. The private key is returned as an unencrypted PEM encoded PKCS#1 private key. If a key with the specified name already exists, Amazon EC2 returns an error.
--
--
-- You can have up to five thousand key pairs per region.
--
-- The key pair returned to you is available only in the region in which you create it. If you prefer, you can create your own key pair using a third-party tool and upload it to any region using 'ImportKeyPair' .
