Short Description

If you have the private SSH key you can re-generate the public key component simply by running the following ssh-keygen command: ssh-keygen -i -f /path/to/private-key /path/to/public-key That much is the simple part. The AWS console and API does not support pushing 2 keypairs when starting an EC2 instance. 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.

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.

This should not be abbreviated and should include suffixes such as Inc, Corp, or LLC.Google Inc.Organizational UnitThe division of your organization handling the certificate.Information TechnologyIT DepartmentCity/LocalityThe city where your organization is located.Mountain ViewState/County/RegionThe state/region where your organization is located. So if you lose the private key, the certificate will no longer work. What is contained in a CSR? NameExplanationExamplesCommon NameThe fully qualified domain name (FQDN) of your server.
