Amazon Web Services: Create CSR and Install SSL Certificate (OpenSSL) Creating a CSR and installing your SSL certificate for Amazon Web Services (AWS) Use the instructions on this page to use OpenSSL to create your certificate signing request (CSR) and then upload and implement your SSL certificate in your AWS instance. Jul 09, 2019 If you need an SSL certificate for Load Balancer, you can generate a CSR code and upload your certificate to AWS with the help of the OpenSSL tool: The command to generate a private key and a CSR code is the following: openssl req -new -newkey rsa:2048 -nodes -keyout example.key -out example.csr. If you create your own key pair using a third-party tool, be sure that your key matches the guidelines at Importing Your Own Public Key to Amazon EC2. Add a new user to the EC2 Linux instance. Connect to your Linux instance using SSH. Use the adduser command to add a new user account to an EC2 instance (replace newuser with the new. Jul 09, 2019 Can I generate a new Private Key for my Certificate if I lose the old one? You can generate a new private key and CSR, or use the automatic CSR and key generation during Certificate reissue (this option is available for all Certificates except for the Multi-Domains). What does the Private Key look like? 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.
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 .

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.
KeyName -> (string)
KeyPairId -> (string)
Aws Ec2 Ssl Certificate
The ID of the key pair.
I lost the private key file for the key pair that is used to launch my Amazon Elastic Compute Cloud (Amazon EC2) Windows instance. How can I replace or change the key pair on an EC2 Windows instance?
Resolution
Generate New Ssl Key Ec2 Access
To change the key pair, create an AMI of the existing instance, and then launch a new instance. You can then select a new key pair by following the instance launch wizard. Follow these steps:
Create a new key pair and save the private key file. You can create a key pair using the console, AWS Command Line Interface (AWS CLI), or AWS Tools for Windows PowerShell. For more information, see Creating a Key Pair Using Amazon EC2. Note: To give the new key pair the same name as the lost key pair, you must first delete the lost key pair.
From the Amazon EC2 console, choose Instances from the navigation pane.
Select your instance. From the Description tab, take note of the Instance type, VPC ID, Subnet ID, Security groups, and IAM role for the instance.
Warning: If this instance has an instance store volume, any data on it is lost when the instance is stopped. If the instance shutdown behavior is set to Terminate, the instance terminates when it is stopped. Stop your instance.
Select your instance. For Actions, choose Image, Create Image. For Image name, enter a name. (Optional) For Image description, enter a description.
Choose Create Image, and then choose Close.
Choose AMIs from the navigation pane. If the Status is pending, the AMI is still being created. When the Status is available, continue to the next step.
Select the AMI, and then choose Launch.
Complete the wizard. Be sure to select the same Instance type, VPC ID, Subnet ID, Security groups, and IAM role as the instance that you are replacing. For Select a key pair, choose the new key pair.
(Optional) If the original instance has an associated Elastic IP address, reassociate the Elastic IP address to the new instance.
(Optional) If any EBS volumes aren't captured during the AMI creation, detach the volume, and then attach the volume to the new instance. Note: When you detach the volume, you can skip the step to unmount the volume, because the original instance is already in stopped state.
