How to use SSH on Windows PuTTY?

 2 min

Use of Public and Private Key while logging into SSH provides security and added convenience. These keys can be used in place of a password so that no username or password is required to connect to the server via SSH. You can also generate keys with a different password from your cPanel password if required.

# Following are the Steps to generate a Public/ Private Key Pair

1. Log in to cPanel and click on the SSH/Shell Access icon under the Security category.

2. Now open Manage SSH Keys tool.

3. Click on Generate a New Key and complete the fields that are shown. For maximum security try using RSA key type and a 4096-bit key size.

Note: There is a bug present in cPanel at this time that does not allow you to create a 2048 or 4096-bit DSA key.

4. The location for the newly generated public and private key will be displayed as well as the key fingerprint.

5. Click on Go Back.

6. Click on Manage Authorization present next to the Public key you have generated. Then click on Authorize to activate your public key.

7. Click on Go Back.

8. Click on View/Download located to the right of the Private Key. Click on the Download Key button. Now Save the file to your computer and click on Go back.

Now, you can use the private key saved on your computer to securely log in with SSH to our server. If you are already using PuTTY then refer following steps for the configuration :
