I want to use the same SSH key pair to access my Amazon Elastic Compute Cloud (Amazon EC2) instances in all my AWS Regions. How do I do that?
Short Description
To use a single SSH key pair for all your AWS Regions, first generate a public SSH key from a private SSH key. Then, import the key into each of your AWS Regions.
Resolution
If you don't have one already, begin by creating an SSH key pair.

Description¶
Retrieves the specified SSH public key, including metadata about the key.
The SSH public key retrieved by this operation is used only for authenticating the associated IAM user to an AWS CodeCommit repository. For more information about using SSH keys to authenticate to an AWS CodeCommit repository, see Set up AWS CodeCommit for SSH Connections in the AWS CodeCommit User Guide .
See also: AWS API Documentation
See 'aws help' for descriptions of global parameters.
Synopsis¶Options¶
--user-name (string)
The name of the IAM user associated with the SSH public key.
This parameter allows (through its regex pattern ) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-
--ssh-public-key-id (string)
The unique identifier for the SSH public key.
This parameter allows (through its regex pattern ) a string of characters that can consist of any upper or lowercased letter or digit.
--encoding (string)
Specifies the public key encoding format to use in the response. Cyberghost vpn key generator.rar. To retrieve the public key in ssh-rsa format, use SSH . To retrieve the public key in PEM format, use PEM .
Possible values:
--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.
