An SSH Key allows you to log into your server without needing a password. SSH Keys can be automatically added to servers during the installation process.
Creating an SSH key on Windows
The simplest way to create SSH key on Windows is to use PuTTYgen.
Apr 12, 2018 In this tutorial we'll learn how to set up SSH-key-based authentication on a CentOS 7 installation. This will happen the first time you connect to a new host. Create a key pair for the new user account. Create a key pair, or use an existing one. Create a.ssh directory in the newuser home directory: $ mkdir.ssh. For Amazon Linux, Amazon Linux 2, RHEL, and CentOS: Use the usermod command to add the user to the wheel group. $ sudo usermod -aG wheel newuser. Apr 02, 2019 SSH keys offer a highly secure manner of logging into a server with SSH as against mere dependence on a password. https://soihnla.weebly.com/blog/windows-7-product-key-online-generator. While a password stands the risk of being finally cracked, SSH keys are rather impossible to decipher using brute force.
Adding your SSH key to the ssh-agent. Before adding a new SSH key to the ssh-agent to manage your keys, you should have checked for existing SSH keys and generated a new SSH key. https://soihnla.weebly.com/blog/autocad-2007-activation-key-generator-free-download. When adding your SSH key to the agent, use the default macOS ssh-add command, and not an application installed by macports, homebrew, or some other external source.
- Download and run PuTTYgen.
- Click the 'Generate' button.
- For additional security, you can enter a key passphrase. This will be required to use the SSH key, and will prevent someone with access to your key file from using the key.
- Once the key has been generated, click 'Save Private Key'. Make sure you save this somewhere safe, as it is not possible to recover this file if it gets lost
- Select all of the text in the 'Public key for pasting into OpenSSH
authorized_keys
file'. This is what you would need to enter into the control panel to use the SSH key.
Creating an SSH key on Linux
The tools to create and use SSH are standard, and should be present on most Linux distributions. With the following commands, you can generate ssh key. Vb.net public private key generator online.
- Run:
ssh-keygen -t rsa
. For a more secure 4096-bit key, run:ssh-keygen -t rsa -b 4096
- Press enter when asked where you want to save the key (this will use the default location).
- Enter a passphrase for your key.
- Run
cat ~/.ssh/id_rsa.pub
- this will give you the key in the proper format to paste into the control panel. - Make sure you backup the
~/.ssh/id_rsa
file. This cannot be recovered if it is lost.
Adding an SSH key to your control panel
Centos Generate New Ssh Host Key Fingerprint
- Once you're logged in, go to https://my.vultr.com/sshkeys.
- Click 'Add SSH Key'.
- Enter a descriptive name for the key.
- Paste in your SSH public key. This is a long string beginning with 'ssh-rsa'. You should have saved this from when you generated your key.
- Click 'Add SSH Key'.
- Now, when you're deploying servers you will be able to select which SSH keys you want to add to the newly deployed server. Remember to select the keys before the initial server deployment, otherwise you will need to log into the newly created server and add the SSH keys manually.
Limitations
- SSH keys are only available for Linux and FreeBSD. They are not supported for Windows, custom ISOs, nor snapshot restores.
- SSH keys can only be managed from the control panel during deployment. You cannot use the control panel to manage them on an already-installed instance.
Connecting to a server using an SSH key from a Windows client
- Download and run the PuTTY SSH client.
- Type the IP address or Username + IP address (
[email protected]
) of the destination server under the 'Host Name' field on the 'Session' category. - Navigate to the 'Connection -> SSH -> Auth' category (left-hand side).
- Click 'Browse..' near 'Private key file for authentication'. Choose the private key file (ending in
.ppk
) that you generated earlier with PuTTYgen. - Click 'Open' to initiate the connection.
- When finished, end your session by pressing
Ctrl+d
.

Connecting to a server using an SSH key from a Linux client
Centos Generate New Ssh Host Key Verification
- Check that your Linux operating system has an SSH client installed (
which ssh
). If a client is not installed, you will need to install one. - Initiate a connection:
ssh -i /path/to/id_rsa [email protected]
- When finished, end your session by pressing
Ctrl+d
