-- 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#8
-- 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. To create a key pair that is available in all regions,
-- use ImportKeyPair.
--
-- For more information about key pairs, see

-- in the /Amazon Elastic Compute Cloud User Guide/.
