Jul 15, 2014 This article will discuss EC2 key pairs and how they can be used to connect to Windows and Linux instances. Amazon AWS uses keys to encrypt and decrypt login information. At the basic level, a sender uses a public key to encrypt data, which its receiver then decrypts using another private key. These two keys. I have an AWS EC2 Instance using EBS and I want to stop the use of the current private key, and use a new one. As I understand it, merely deleting the key pair on the AWS Console just deletes the public key and does not prevent access to the instance using the (old) private key via SSH.
[ aws . ec2 ]
Description¶
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.

Perform ssh using new key. I have a running EC2 Instance ( Ubuntu 14.04 ) having key-pair “testing-key”. Let’s change the key. Create a new key pair from AWS Console. This is a private key that you have to download on your local machine. Generate Public Key from Private Key (testing-ssh-key) Execute '$ ssh-keygen -y' and provide the path for private key. Here “testing.
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 .

Synopsis¶Options¶
--key-name (string)
Aws Generate New Key Pair Form Running Instance Form
A unique name for the key pair.
Constraints: Up to 255 ASCII characters
--dry-run | --no-dry-run (boolean)
Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .
--tag-specifications (list)
Shorthand Syntax:
JSON Syntax:
--cli-input-json (string)Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.
--generate-cli-skeleton (string)Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
See 'aws help' for descriptions of global parameters.

To create a key pair
This example creates a key pair named MyKeyPair.
Command:
The output is an ASCII version of the private key and key fingerprint. You need to save the key to a file.
