def create_key_pair(DryRun=None, KeyName=None):
    """
    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 Key Pairs in the Amazon Elastic Compute Cloud User Guide .
