One effective way of securing SSH access to your cloud server is to use a public-private key pair. This means that a public key is placed on the server and a private key is placed on your local workstation. PuTTYgen is an key generator tool for creating SSH keys for PuTTY. It is analogous to the ssh-keygen tool used in some other SSH implementations. The basic function is to create public and private key pairs. PuTTY stores keys in its own format in.ppk files. However, the tool can also convert keys to and from other formats. The.pub file is your public key, and the other file is the corresponding private key. If you don’t have these files (or you don’t even have a.ssh directory), you can create them by running a program called ssh-keygen, which is provided with the SSH package on Linux/macOS systems and comes with Git for Windows. Jun 22, 2012  SSH keys provide a more secure way of logging into a virtual private server with SSH than using a password alone. With SSH keys, users can log into a server without a password. This tutorial explains how to generate, use, and upload an SSH Key Pair. Use the ssh-keygen command to generate SSH public and private key files. By default, these files are created in the /.ssh directory. You can specify a different location, and an optional password (passphrase) to access the private key file. If an SSH key pair with the same name exists in the given location, those files are overwritten. The ssh-keygen utility displays a message indicating that the private key has been saved as filename and the public key has been saved as filename.pub. It also displays information about the key fingerprint and randomart image. Generating an SSH Key Pair on Windows Using the PuTTYgen Program.

SSH keys are a way to identify trusted computers, without involving passwords. The steps below will walk you through generating an SSH key and adding the public key to the server. /app-jwt-nexmo-jwt-generate-privatekey-applicationid-yourappid.html.

Step 1: Check for SSH Keys

First, check for existing SSH keys on your computer. Open Git Bash, Cygwin, or Terminal, etc. and enter:

Check the directory listing to see if you already have a public SSH key. By default, the filenames of the public keys are one of the following:

• id_dsa.pub
• is_ecdsa.pub
• id_ed25519.pub
• id_rsa.pub

If you see an existing public and private key pair listed (for example id_rsa.pub and id_rsa) that you’d like to use, you can skip Step 2 and go straight to Step 3.

Step 2: Generate a new SSH key

With your command line tool still open, enter the text shown below. Make sure you substitute in your email address:

You’ll be asked to enter a passphrase, or simply press Enter to not enter a passphrase:

After you enter a passphrase (or just press Enter twice), review the fingerprint, or ‘id’ of your SSH key:

Step 3: Add your key to the ssh-agent

Ssh Using Public Key

To configure the ssh-agent program to use your SSH key, first ensure ssh-agent is enabled.

If you are using Git Bash, turn on the ssh-agent with command shown below instead:

Then, add your SSH key to the ssh-agent:

Step 4: Add your SSH key to the server

To add your public SSH key to the server, you’ll copy the public SSH key you just created to the server. Substitute “username” with your username on the server, and “server.address.com” with the domain address or IP address of your server:

Ssh Show Public Key

The server will then prompt you for your password:

That’s it! You should now be set up to connect to the server without having to authenticate.
