PuTTY doesn't natively support the private key format (.pem) generated by Amazon EC2. You must convert your private key into a.ppk file before you can connect to your instance using PuTTY. You can use the PuTTYgen tool for this conversion. This tool, available for both Windows and Unix operating system, can convert keys. Generate your SSH Key pair by clicking the Generate button. When the progress bar starts loading, move your mouse randomly across the area to load up the bar and generate your key pair. Your public SSH key will be displayed on the screen. This guide describes how to generate and use a private/public key pair to log in to a remote system with SSH using PuTTY. PuTTY is an SSH client that is available for Windows and Linux (although it is more common on Windows systems).

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.

Generate keys

Generate A Key Pair From Putty

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.

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.

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

  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.

As a security precaution, always generate a new CSR and private key when you are renewing a certificate. Clinging to the same private key is a road paved with security vulnerabilities. We provide here detailed instructions on how to create a private key and self-signed certificate valid for 365 days. Follow this article if you need to generate a private key and a self-signed certificate, such as to secure GSX Gizmo access using HTTPS. It should be saved safely on the server you generated it on. Do not send your private key to anyone, as that can compromise the security of your certificate. If you lose your private key, you will be unable to install your SSL certificate and will need to generate a new key pair (CSR + Private Key) and re-issue the certificate. To assign the existing private key to a new certificate, you must use the Microsoft Windows Server 2003 version of Certutil.exe. To do this, follow these steps: Log on to the computer that issued the certificate request by using an account that has administrative permissions. 2020-3-11  If you are using Dynamic DNS, your CN should have a wild-card, for example:.api.com. Otherwise, use the hostname or IP address set in your Gateway Cluster (for example. 192.16.183.131 or dp1.acme.com). Run the following OpenSSL command to generate your private key and public certificate. Answer the questions and enter the Common Name when. Have an installer generate a private key and certificate free.

  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.
