Ssh Generate Key For User
This section of Getting Started assumes that:
- You have recently installed Bitvise SSH Server.
- You have configured the SSH Server for access using SFTP, for Git access, or another purpose.
- You have installed Bitvise SSH Client on the computer from which you wish to connect.
- You wish to configure public key authentication between the SSH Server and Client.
Before you configure public key authentication, it is important to understand:
- Public keys, in the way they are commonly used in SSH, are not X.509 certificates.
- Client authentication keys are separate from server authentication keys (host keys).
- A keypair consists of a private key and a public key, which are separate.
- A private key should never be sent to another party. It is private.
If this is the first time you are using public keys, we recommend the page Public keys in SSH.

← ServerPilot Docs. How to Use SSH Public Key Authentication Overview. Public key authentication is a way of logging into an SSH/SFTP account using a cryptographic key rather than a password. If you use very strong SSH/SFTP passwords, your accounts are already safe from brute force attacks.
To use public key authentication, the client from which you are connecting needs to have a public/private keypair. To generate a keypair using Bitvise SSH Client, run the graphical SSH Client, and open the Client key manager:
Press the Generate button to generate a new keypair:
$ ssh-keygen -b 4096 Generate 4098 Bit Key Generate 4096 Bit DSA KeyRSA is very old and popular asymmetric encryption algorithm. We can not generate 4096 bit DSA keys because it algorithm do not supports. It is used most of the systems by default. Generate 2048 Bit KeyThe default key size for the ssh-keygen is 2048 bit. Generate 256 bit encryption key. There are some alternatives to RSA like DSA.
- Update and verify the new user account credentials. After you retrieve the public key, use the command shell session that is running under the context of the new user account to confirm that you have permission to add the public key to the.ssh/authorizedkeys file for this account: 1. Run the Linux cat command in append mode.
- Jul 29, 2019 On your client system – the one you’re using to connect to the server – you need to create a pair of key codes. To generate a pair of SSH key codes, enter the commands: mkdir –p $HOME/.ssh chmod 0700 $HOME/.ssh ssh-keygen. This will create a hidden directory to store your SSH keys, and modify the permissions for that directory.
- How to Generate SSH Public/Private Keys on Windows By Alexandru Andrei – Posted on Sep 17, 2019 Sep 17, 2019 in Windows If you ever managed a Linux server from Windows, you probably used PuTTY or at least heard about it.
- Attention: SSH Authorized User Key names should not identify an associated trading partner. Select a naming convention where trading partners remain anonymous. Anyone with access to the dashboard My Account interface can see a list of all SSH Authorized User Key names in the system, not just their own.
- If you don't already have an SSH key, you must generate a new SSH key.If you're unsure whether you already have an SSH key, check for existing keys. If you don't want to reenter your passphrase every time you use your SSH key, you can add your key to the SSH agent, which manages your SSH keys and remembers your passphrase.

Guidelines:
Unless required for compatibility reasons, do not generate a DSA keypair. Only 1024-bit DSA keys are interoperable in SSH, and this key size is no longer considered adequate when using the DSA algorithm. Generate either an ECDSA keypair, or an RSA keypair of size 2048 bits or larger.
If you have saved a named SSH Client profile, the keypair generation interface will offer to store the keypair either in the profile, or globally.
When the keypair is stored globally, it is stored in the Windows registry for the current user, under HKCUSoftwareBitviseKeypairs.
It may be useful to store the keypair in a profile if the profile is going to be used on other computers, or by a job that runs as a different Windows account on the same computer. In SSH Client versions 7.xx and higher, the setting Sensitive information accessibility on the Login tab controls whether a keypair stored in the profile can be read by another Windows user, or on another computer.
You can choose a passphrase with which to protect the keypair. If you enter a passphrase, you will need to provide it every time the keypair is used for authentication.
Before you can use public key authentication, the public key for the keypair you have generated must be configured in the SSH Server. If you are able to connect to the SSH Server using password authentication, you can connect to the server and upload the public key using the Client key manager:
If the SSH Server does not allow you to connect using password authentication, or does not allow you to upload the key, you will need to send the public key to the server administrator using an alternate method of communication. To do this, export the public key using the Client key manager:
For help with importing the public key into Bitvise SSH Server, check the Public Key Authentication section of our SSH Server Usage FAQ.
Once the public key has been uploaded or imported for your account in the SSH Server, configure the SSH Client to enable public key authentication on the Login tab:
You should now be able to connect to the SSH Server using your public key:
Save the profile to preserve this configuration.
How to generate an SSH key in Windows 10
To generate an SSH key in Windows 10:
- Ensure the Windows 10 OpenSSH client is installed.
- Run “ssh-keygen” in Command Prompt and follow the instructions to generate your key.
Applies to Windows 10 1803, and up
Generating SSH keys in a Windows environment used to be a convoluted process which required the installation of third-party tools. Since the Windows 10 April 2018 update, Windows has shipped with a preinstalled OpenSSH client, which means you can use ssh-keygen to generate SSH keys. Read on as we walk you through the entire process.
First, you’ll need to make sure OpenSSH is installed on your machine – if you upgraded from an earlier version of Windows 10, you may need to manually enable it. Launch the Settings app and click the “Apps” category. Next, click the “Manage optional features” link. If you don’t see “OpenSSH Client” in the list which appears, click the “Add a feature” button and install it. You might need to reboot your PC after the installation.
Once OpenSSH is installed, you’re ready to proceed. Open Command Prompt from the Start menu. Type “ssh-keygen” (without the quotes) into the terminal window and press enter. You’ll be prompted to confirm the save location. We recommend pressing enter to use the default location in your user directory. Otherwise, type a path to save the key in and then press enter.

You can now choose to add a passphrase (password) to the key. If you add one, you’ll need to supply it whenever you use the key. Either type a passphrase and press enter or press enter immediately to proceed without one.
Windows will now generate your RSA public/private key pair. The public key will be stored as “id_rsa.pub” in the directory you specified. Upload this key to any machines you need to SSH into. You can then open a connection using Windows’ built-in SSH client – type “ssh [email protected]” to connect and authenticate using your generated credentials.
