SSH keys are one of the most secure SSH authentication options. It is definitely more secure than the usual SSH password authentication. Therefore, it is highly recommended to use SSH Key authentication method for connections to your servers.
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. Mar 30, 2019 Setup SSH key to connect to Github with Putty. Generate SSH key. This procedure generates two files:.ssh/idrsa and.ssh/idrsa.pub. Add public key to Github. Setup SSH agent. Use puttygen to convert the private key (idrsa) to ppk (idrsa.ppk). You can generate an SSH key on Windows using the PuTTY SSH client. You can download PuTTY for free from this URL. To generate a key with PuTTY, you should: Download and start the puttygen.exe generator. In the 'Parameters' section choose SSH2 DSA and press Generate. Move your mouse randomly in the small screen in order to generate the key pairs.
- Generate a ssh key using puttygen.exe (ssh2-rsa, 4096, comment=GitLab, and set a passphrase) Add key to pageant.exe and the public key to your GitLab profile Ensure you start a new command shell so that git recognizes the GITSSH value Try these two commands to check connection first.
- I've generated key pairs using PuTTYgen and been logging in using Pageant, so that I have to enter my pass-phrase only once when my system boots. How do I achieve this in Linux? I've heard of key.

With password authentication, you can connect to your server from any location, you only need to fill in your password. However, if your password gets leaked, it is a major risk as anyone who knows your password will be able to get into the server.
SSH Key authentication only allows connections from clients whose key matches the one on the server. Basically, you generate a key pair (private key and public key). The private key is placed on your local machine and the public key is uploaded to the server. When connecting to the server, a validation of these two keys is made and if the key pair passes the validation you are allowed to connect. Of course, you can upload keys of multiple users so that you or other authorized users would be able to connect to the server from different computers.
As you can see this is a much safer connection method. In this tutorial, we will focus on Windows users who use PuTTY for connections to the server and show how to generate PuTTYSSH Keys. If you want to generate SSH Keys on Linux or Mac, see this tutorial.
What you’ll need
Before you begin this guide you’ll need the following:
- Access to your Linux server / VPS
- PuTTY and PuTTYgen installed on your computer (Download here)
Step 1 — Downloading PuTTYgen
Most of you have PuTTY installed on your computers already, however, to generate SSH Keys you also will need PuTTYgen.
- Download PuTTYgenhere
- You should be able to see this file downloaded:
Add Ssh Key To Putty
No installation is required for PuTTYgen, it will run when you execute the file.
Step 2 — Generating your SSH Key pair
- Open up PuTTYgen by double clicking on the puttygen.exe file you have downloaded in Step 1.
- You should be able to see a window like this:
- Before generating your SSH Key pair, you can edit some settings, for example, key length, however, in most cases the default options will work just fine.
- 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:
- For additional security it is highly recommended to think of a passphrase for your SSH key (However, you can also leave it empty):
- Save your private key to any desired location on your computer and name it anything you like.
- Save your public key to the same location on your computer and name it anything you like.
And that is it, you have generated your SSH Key pair. The private key will stay on your computer (do not provide it to anyone) while your public key needs to be uploaded to the server you wish to connect to.
Step 3 — Setting up your private key on PuTTY
In order for the server to recognize your computer when connecting from PuTTY, you need to attach the private key to PuTTY.
- Open up PuTTY.
- Navigate to Connection -> SSH -> Auth in the left sidebar.
- Browse for your private key file in the field Private key for authentication
- Select the private key file with .ppk ending and click Open.
Step 4 – Adding public key to server
Lastly, you need to upload your public key to the server:
- On your local computer, open public key file (id_rsa.pub) you generated in Step 2 with any text editor and copy its contents (public key).
- Connect to your VPS using Putty. See this guide for detailed steps.
- If .ssh folder does not exist, create it together with authorized_keys file with the following command:
mkdir ~/.ssh | touch ~/.ssh/authorized_keys
- Secure SSH Key file by changing permissions:
chmod 0700 ~/.ssh; chmod 0644 ~/.ssh/authorized_keys
- Open authorized_keys file with vim text editor:
vim ~/.ssh/authorized_keys
- Press i key on your keyboard and right mouse button to paste the public key.
- Press Esc button and type in
:x
, hit Enter button. This command will save changes made to the file.
That is it, you can now use SSH keys instead of SSH password authentication to connect to your VPS.
Conclusion
You have learned how to generate PuTTY SSH Keys using PuTTYgen. This will make your connection to the server a lot more secure and convenient as you will not need to fill in the password each time. We recommend using this way of SSH authentication at all times and disable password authentication for good to completely secure your server. To find out how to completely disable SSH Password authentication on your server and use SSH Key authentication instead, follow this tutorial: How to disable SSH Password authentication on VPS.

Overview
OSG Connect requires SSH-key-based logins. You need to followa two-step process to set up the SSH key to your account.
- Generate a SSH key pair.
- Add your public key to the submit host by uploading it toyour OSG Connect user profile (via the OSG Connect website).
After completing the process, you can log in from a local computer(your laptop or desktop) to the OSG Connect login node assignedusing either ssh or an ssh program like Putty -- see below formore details on logging in.
NOTE: Please do not edit the authorized keys file on the login node.
Step 1: Generate SSH Keys
We will discuss how to generate a SSH key pair for two cases: Where is the battery key on zagg ipad 4th generation case.
- 'Unix' systems (Linux, Mac) and certain, latest versions of Windows
- Older Windows systems
Please note: The key pair consist of a private key and a public key. You will upload thepublic key to OSG Connect, but you also need to keep a copy of the private key to log in!
You should keep the private key on machines that you havedirect access to, i.e. your local computer (your laptop or desktop).

When everything has successfully completed, the output should resemble thefollowing:
The part you want to upload is the content of the
.pub
file (~/.ssh/id_rsa.pub)Windows, using Putty to log in
If you can connect using the
ssh
command within the Command Prompt (Windows 10 build version 1803 and later), please follow the Mac/Linux directions above. If not,continue with the directions below.- Open the
PuTTYgen
program. You can downloadPuttyGen
here: PuttyGen Download Page,scroll down until you see theputtygen.exe
file. - For Type of key to generate, select RSA or SSH-2 RSA.
- Click the 'Generate' button.
- Move your mouse in the area below the progress bar.When the progress bar is full, PuTTYgen generates your key pair.
- Type a passphrase in the 'Key passphrase' field. Type the same passphrase in the 'Confirm passphrase' field. Youcan use a key without a passphrase, but this is not recommended.
- Click the 'Save private key' button to save the private key. You must save the private key. You will need it to connect to your machine.
- Right-click in the text field labeled 'Public key for pasting into OpenSSH authorized_keys file' and choose Select All.
- Right-click again in the same text field and choose Copy.
Step 2: Add the public SSH key to login node
To add your public key to the OSG Connect log in node:
Generate Ssh Key Aix
- Go to www.osgconnect.net and sign in with the institutional identity you used when requesting an OSG Connect account.
- Click 'Profile' in the top right corner.
- Click the 'Edit Profile' button located after the user information in the left hand box.
- Copy/paste the public key which is found in the
.pub
file into the 'SSH Public Key' text box.The expected key is a single line, with three fields looking something likessh-rsa ASSFFSAF.. user@host
. If you used the first set of key-generatinginstructions it is the content of~/.ssh/id_rsa.pub
and for the second (usingPuTTYgen), it is the content from step 7 above. - Click 'Update Profile'
The key is now added to your profile in the OSG Connect website. This will automaticallybe added to the login nodes within a couple hours.
Logging In
After following the steps above to upload your key and it's been a few hours, you shouldbe able to log in to OSG Connect.
Determine which login node to use
Before you can connect, you will need to know which login node your account is assigned to. You can findthis information on your profile from the OSG Connect website.
- Go to www.osgconnect.net and sign in with your CILogin.
- Click 'Profile' in the top right corner.
- The assigned login nodes are listed in the left side box. Make note of the address ofyour assigned login node as you will use this to connect to OSG Connect.
For Mac, Linux, or newer versions of Windows
Open a terminal and type in:
It will ask for the passphrase for your ssh key (if you set one) and then youshould be logged in.
For older versions of Windows
On older versions of Windows, you can use the Putty program to log in.
- Open the
PutTTY
program. If necessary, you can download PuTTY from the website here PuTTY download page. - Type the address of your assigned login node as the hostname (see 'Determine which login node to use' above).
- In the left hand menu, click the '+' next to 'SSH' to expand the menu.
- Click 'Auth' in the 'SSH' menu.
- Click 'Browse' and specify the private key file you saved in step 5 above.
- Click 'Open' and provide your passphrase when prompted to do so.
