Step 2: Add Your Key to Your Amazon EC2 Instance. Use the following command to copy your key to your Amazon EC2 instance. /you/.ssh/idrsa.pub is the location to your ssh key, pemfile.pem is the.pem file you normally use to login, and user@ec2-instance.com is the user and hostname to your EC2 instance.

[ aws . ec2 ]

1. Turns out that Amazon does not provide ssl certificates for their EC2 instances out of box. I skipped the part that they are a virtual servers providers. To install ssl certificate even the basic one, you need to buy it from someone and install it manually on your server. I used startssl.com They provide free basic ssl certificates.
2. The simplest way to generate a key pair is to run ssh-keygen without arguments. In this case, it will prompt for the file in which to store keys. Here's an example: klar (11:39) ssh-keygen Generating public/private rsa key pair.

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.

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 .

For more information, see Key Pairs in the Amazon Elastic Compute Cloud User Guide .

See 'aws help' for descriptions of global parameters.

Synopsis¶

Options¶

--key-name (string)

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 .

--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.

Examples¶

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.

For more information, see Using Key Pairs in the AWS Command Line Interface User Guide.

Output¶

KeyFingerprint -> (string)

KeyMaterial -> (string)

An unencrypted PEM encoded RSA private key.

How To Generate Ssl

KeyName -> (string)

KeyPairId -> (string)

The ID of the key pair.

Replace username with your user name, such as ec2-user. You can enter the default user name, or enter a custom user name, if one was previously set up for the instance. For a list of default user names, see General Prerequisites for Connecting to Your Instance.

Replace PublicKeypair with the public key retrieved in step 2. Be sure to enter the entire public key, starting with ssh-rsa.

7. Choose Save.

8. Start your instance.

9. After the cloud-init phase is complete, validate that the public key was replaced.

Important: Because the script contains a key pair, remove the script from the User Data field.

10. Stop your instance.

11. Choose Actions, Instance Settings, and then choose View/Change User Data.

12. Delete all the text in the View/Change User Data dialog box, and then choose Save.

13. Start your instance.

Note: If your instance is Amazon Linux 2 2.0.20190618 or later, you can use EC2 Instance Connect to connect to the instance.

Method 2: Use AWS Systems Manager

If your unreachable instance is listed in AWS Systems Manager as a managed instance, you can use the AWSSupport-ResetAccess document to recover from a lost key pair scenario. This Automation document uses the EC2Rescue for Linux tool on the specified EC2 instance to automatically generate and add a new SSH (Public/Private) key pair.

The new SSH private key for your instance is encrypted and saved in the Parameter Store. The parameter name is /ec2rl/openssh/instance_id/key. Create a new .pem file with this parameter's value as its content and use it to connect back to your unreachable instance.

Note: The Automation workflow creates a backup, password-enabled Amazon Machine Image (AMI). The new AMI is not automatically deleted and remains in your account.

To locate these AMIs:
