Generate RSA keys with SSH by using PuTTYgen

Oct 02, 2015 SSH Config and crypto key generate RSA command. Use this command to generate RSA key pairs for your Cisco device (such as a router). Keys are generated in pairs–one public RSA key and one private RSA key. If your router already has RSA keys when you issue this command, you will be warned and prompted to replace the existing keys with new keys. I tried to use the CLI interface to enable public key authentication, but it would not accept the format for my private RSA key. Once I get that working, I’ll update this post with the CLI commands that will accomplish what we will do through the GUI for now. First, click on Security, then SSH Server and finally SSH User Authentication. Nov 17, 2016 Generate the rsa key. In this tutorial we will use a key which we will generate in a Linux box shortly rather than this one (router key), so why to generate this key in the router? It’s because to enable the ssh in Cisco router a local rsa key is mandatory, without the key you cannot enable ssh. Let’s generate the key. Click the Add button and you’ll get the Add SSH User window pop up. Make sure the Key Type is set to RSA and then go ahead and open your public SSH key file that you saved earlier using a program like Notepad. Copy the entire contents and paste it into the Public Key window.

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

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.

/finale-key-generator-version-25.html. 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.

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.
