Generate A Pair Of Keys

32

To generate the public/private key pair, enter this in the Command Prompt: ssh-keygen At the first prompt, “Enter file in which to save the key,” press Enter to save it in the default location. Generate a key pair with a third-party tool of your choice. Save the public key to a local file. For example, /.ssh/my-key-pair.pub (Linux) or C:keysmy-key-pair.pub. Save the private key to a different local file that has the.pem extension. Jul 29, 2019  This will create a hidden directory to store your SSH keys, and modify the permissions for that directory. The ssh-keygen command creates a 2048-bit RSA key pair. For extra security, use RSA4096: ssh –keygen –t rsa 4096. If you’ve already generated a key pair, this will prompt to overwrite them, and those old keys will not work anymore.

Generate RSA keys with SSH by using PuTTYgen

One effective way of securing SSH access to your cloud server is to usea public-private key pair. This means that a public key is placed onthe server and a private key is placed on your local workstation.Using a key pair makes it impossible for someone to log in by using justa password, as long as you set up SSH to deny password-basedauthentication.

This article provides steps for generating RSA keys by using PuTTYgen onWindows for secure SSH authentication with OpenSSH.

Access keys are long-term credentials for an IAM user or the AWS account root user. You can use access keys to sign programmatic requests to the AWS CLI or AWS API (directly or using the AWS SDK). Sep 26, 2019  Generating an SSH key. An SSH key consists of a pair of files. One is the private key, which should never be shared with anyone. The other is the public key. The other file is a public key which allows you to log into the containers and VMs you provision. SiteGround uses key-based authentication for SSH. This has proven more secure over standard username/password authentication. More information on SSH keys can be found here. You can generate an SSH key pair directly in cPanel, or you can generate the keys yourself and just upload the public one in cPanel to use with your hosting account.

Generate keys

In Windows, use PuTTYgen to generate your public and private keys.

  1. If needed, download PuTTYgen from the PuTTY download page.(PuTTYgen might have been installed previously with PuTTY or WinSCP.)
  2. Launch the program, and then click the Generate button.The program generates the keys for you.
  3. Enter a unique key passphrase in the Key passphrase andConfirm passphrase fields.For additional information about using passphrases,see Log in with a SSH Private Key on Windows.
  4. Save the public and private keys by clicking the Save public keyand Save private key buttons.
  5. From the Public key for pasting into OpenSSH authorized_keys filefield at the top of the window, copy all the text (starting with ssh-rsa)to your clipboard by pressing Ctrl-C.You need this key available on your clipboard to paste eitherinto the public key tool in the Control Panel or directly into theauthorized keys on your cloud server.

Use the key pair

You can use the RSA key pair in the following ways.

Specify your SSH key when creating a new cloud server

When you create a cloud server, you can assign a public key from the list of keys.If your key is not already in the list, you may add it, and then assign it.

Keys

Add a new public key to the list

  1. Under Advanced Options on the Create Server page, click Manage SSHKeys.
  2. Select public key for the cloud server from the SSH Keys listand click Add Public Key.
  3. Enter the key name, select the region, and paste the entire publickey into the Public Key field. Then click Add Public Key.
  4. Go back to the Create Server page, and confirm that your key is listedin the SSH Key list.

Assign a public key

Generate A Ssh Key Pair

  1. Under Advanced Options on the Create Server page, select the publickey you want to use from the SSH key drop-down menu.
  2. When you are done specifying the all the other details for the server,click Create Server.

Assign your SSH Key to an existing cloud server

To make use of your newly generated RSA key pair, you must tell PuTTY touse it when connecting to your cloud server.

  1. To edit the file (or create it), run the following command on the cloud server:

  2. Paste the text onto its own line in the file.

    You must have the key available in your clipboard to paste it. The key and itsassociated text (the ssh-rsa identified at the start and the comment at the end)must be on one line in the file. If the text is word-wrapped onto multiple linesan error might occur when connecting.

  3. If you created the authorized_keys file, change its permissionsafter you’re done editing it by running the following command:

  4. Open PuTTY, and go to the SSH > Auth section.

  5. Browse to the location of the key file, and load the private key.

  6. Go to the Session page, and save the session. This saves the configurationso that PuTTY uses the key every time that you connect to your cloudserver.

After you save your session, your key is loaded automatically when youconnect to your server.
