How To Configure SSH Keys Authentication With PuTTY And Linux Server In 5 Quick Steps. This tutorial explains how you can replace password-based SSH authentication with key-based authentication which is more secure because only the people that own the key can log in. May 01, 2015 This video shows how to use Putty Gen to create a Key Pair, upload Public Key into AWS Cloud, use that Public Key to launch an instance, and use the private key to access the VM instance. Generate SSH Key using PuTTYgen. With PuTTYgen you can generate SSH key pairs (public and private key) that are used by PuTTY to connect to your server from a Windows client. The private key will be stored on your local machine, while the public key has to be uploaded in your dashboard.

To use an open SSH connection from your development machine to the server VM in your Azure Stack Hub instance that hosts your web app, you might need to create a Secure Shell (SSH) public and private key pair.
In this article, you create your keys and then use them to connect to your server. You can use an SSH client to get a bash prompt on the Linux server or use a Secure FTP (SFTP) client to move files to and from the server.
Create an SSH public key on Windows
In this section, you use PuTTY Key Generator to create a public SSH key and private key pair to use when you create a secure connection to Linux machines in your Azure Stack Hub instance. PuTTY is a free terminal emulator that can allow you to connect to a server via SSH and Telnet.
- Open PuTTY Key Generator.
- Under Parameters, select RSA.
- In the Number of bits in a generated key box, enter 2048.
- Select Generate.
- In the Key area, generate some random characters by moving the cursor over the blank area.
- Enter a Key passphrase and confirm it in the Confirm passphrase box. Note your passphrase for later use.
- Select Save public key, and save it to a location where you can access it.
- Select Save private key, and save it to a location where you can access it. Remember that it belongs with the public key.
Your public key is stored in the text file you saved. The text looks like the following:
When an application requests the key, you copy and paste the entire contents of the text file.

Connect with SSH by using PuTTY
When you install PuTTY, you have both PuTTY Key Generator and an SSH client. In this section, you open the SSH client, PuTTY, and configure your connection values and SSH key. If you're on the same network as your Azure Stack Hub instance, you connect to your VM.
Before you connect, you will need:
- PuTTY
- The IP address and username for the Linux machine in your Azure Stack Hub instance that uses an SSH public key as the Authentication type.
- Port 22 to be open for the machine.
- The public SSH key that you used when you created the machine.
- The client machine that runs PuTTY to be on the same network as your Azure Stack Hub instance.
- Open PuTTY.
- In the Host Name (or IP address) box, enter the username and public IP address of the machine (for example, [email protected]).
- Validate that the Port is 22 and the Connection type is SSH.
- In the Category tree, expand SSH and Auth.
- Next to the Private key file for authentication box, select Browse, and then search for the private key file (<filename>.ppk) of your public and private key pair.
- In the Category tree, select Session.
- Under Saved Sessions, enter a name for the session, and then select Save.Gta v cd key generator download free version.

- In the Saved Sessions list, select the name of your session, and then select Load.
- Select Open. The SSH session opens.
Connect with SFTP with FileZilla
To move files to and from your Linux machine, you can use FileZilla, an FTP client that supports Secure FTP (SFTP). FileZilla runs on Windows 10, Linux, and macOS. The FileZilla client supports FTP, FTP over TLS (FTPS), and SFTP. It is open-source software that's distributed free of charge under the terms of the GNU General Public License.
Set your connection
- Download and install FileZilla.
- Open FileZilla.
- Select File > Site Manager.
- In the Protocol drop-down list, select SFTP - SSH File Transfer Protocol.
- In the Host box, enter the public IP address for your machine.
- In the Logon Type box, select Normal.
- Enter your username and password.
- Select OK.
- Select Edit > Settings.
- In the Select page tree, expand Connection, and then select SFTP.
- Select Add key file, and then enter your private key file (for example, <filename>.ppk).
- Select OK.
Open your connection

With PuTTYgen you can generate SSH key pairs (public and private key) that are used by PuTTY to connect to your server from a Windows client. The private key will be stored on your local machine, while the public key has to be uploaded in your dashboard. When connecting with PuTTY, your session loaded with your private key will generate a signature which will be authenticated by the server using the matching public key.
Step 1: Download PuTTYgen
Simply download and save the PuTTYgen executable (.exe) file from this link. Since it’s a standalone application, you will not need to perform any installation steps for it.
Step 2: Generate SSH Key
- Open PuTTYgen.
- Select these parameters:
- Jelastic requires an SSH-2 RSA (recommended) or SSH-2 DSA key
- The number of bits can be either 2048 or 4096 (recommended). This defines the strength of the key and its resistance to brute-force attacks.
- Click the Generate button.
- Move your mouse randomly within the empty area to generate your key until the progress bar fills up.
- In the next screen you can see the following:
Your Public Key
You can copy and paste this key directly to your Jelastic dashboard. To see how to add your public key to Jelastic, please see: How to connect to Jelastic using PuTTY
Your Key Fingerprint
In this field you should enter something to help you remember what you will use this key for. For example if you are going to use this key pair to connect to your Jelastic environments, you could enter ‘Jelastic’ here.
Key passphrase
Here you can set a password you can use to encrypt your Private Key. While this is not mandatory, it is strongly recommended to ensure that nobody from your workstation will be able to connect to your server without knowing the passphrase.
If you are using SSH for scripts, you will need to leave the Key passphrase field empty.
Step 3: Save your SSH key
You can either copy and paste your public key into the Jelastic dashboard, or you can click the ‘Save public key’ button to save the file on your computer. You can open it with a simple text editor, like Notepad.
You should save the private key on your computer as a .ppk (PuTTY Private Key) file.
Step 4: Load a previous SSH key
If you would like to change the comment or passphrase for an existing SSH key, or you would simply like to view the fingerprint or maybe save another copy of the public key, you can always load your SSH key in PuTTYgen.
May 13, 2013 With an OTP token, the key is hardware protected If the OTP is received on your phone, the key always stays at the server Those few characteristics make the OTP a strong authentication protocol. The weakness in an authentication is usually the human factor. The YubiKey OTP generation is made up of the following fields, encrypted with a unique AES-128 bit key. The result is the 32 character modhex string included after the 12 character public ID. Jan 25, 2017 The following code explains how to generate such Passwords and OTP within no time and what code we can use if in case we need to do so. Method 1: Java program explaining the generation of. Otp generation of the key. Bottom line, a smaller generator effectively results in, not a true OTP, but a much smaller 'key' (generator) that can be broken/discovered. Bottom line: gain the advantage of 'unlimited key sizes' without the need to generate a perfectly random byte array, and without the vulnerability associated with key reuse.
