Apr 19, 2019 In order to properly configure a Windows client for authenticating via SSH keys, the public key (.PUB) file must be transferred to the client device's.ssh directory and stored in the authorized. 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. If you have Windows 10 with the OpenSSH client you may be able to generate the key, but you will have trouble copying it to the target Linux box as the ssh-copy-id command is not part of the client toolset. How to generate an SSH key in Windows 10. Windows will now generate your RSA public/private key pair. The public key will be stored as “idrsa.pub” in. But its authentication mechanism, where a private local key is paired with a public remote key, is used to secure all kinds of online services, from GitHub and Launchpad to Linux running on Microsoft’s Azure cloud. Generating these keys from Linux is easy, and thanks to Ubuntu on Windows, you can follow.

2 Generate a private and public key pair: Go to the Windows Start menu - All Programs - PuTTY and open PuTTYgen; Click the 'Generate' button and PuTTYgen will ask you to make some random movement with your mouse until it has enough random data to generate a secure key for you; Click the 'Save private key' button and save the resulting file.

Most authentication in Windows environments is done with a username-password pair.This works well for systems that share a common domain.When working across domains, such as between on-premise and cloud-hosted systems, it becomes more difficult.

By comparison, Linux environments commonly use public-key/private-key pairs to drive authentication.OpenSSH includes tools to help support this, specifically:

  • ssh-keygen for generating secure keys
  • ssh-agent and ssh-add for securely storing private keys
  • scp and sftp to securely copy public key files during initial use of a server

This document provides an overview of how to use these tools on Windows to begin using key authentication with SSH.If you are unfamiliar with SSH key management, we strongly recommend you review NIST document IR 7966 titled 'Security of Interactive and Automated Access Management Using Secure Shell (SSH).'

About key pairs

Key pairs refer to the public and private key files that are used by certain authentication protocols.

SSH public-key authentication uses asymmetric cryptographic algorithms to generate two key files – one 'private' and the other 'public'. The private key files are the equivalent of a password, and should protected under all circumstances. If someone acquires your private key, they can log in as you to any SSH server you have access to. The public key is what is placed on the SSH server, and may be shared without compromising the private key.

When using key authentication with an SSH server, the SSH server and client compare the public key for username provided against the private key. If the public key cannot be validated against the client-side private key, authentication fails.

Multi-factor authentication may be implemented with key pairs by requiring that a passphrase be supplied when the key pair is generated (see key generation below).During authentication the user is prompted for the passphrase, which is used along with the presence of the private key on the SSH client to authenticate the user.

Host key generation

Public keys have specific ACL requirements that, on Windows, equate to only allowing access to administrators and System.To make this easier,

  • The OpenSSHUtils PowerShell module has been created to set the key ACLs properly, and should be installed on the server
  • On first use of sshd, the key pair for the host will be automatically generated. If ssh-agent is running, the keys will be automatically added to the local store.

To make key authentication easy with an SSH server, run the following commands from an elevated PowerShell prompt:

Since there is no user associated with the sshd service, the host keys are stored under ProgramDatassh.

User key generation

To use key-based authentication, you first need to generate some public/private key pairs for your client.From PowerShell or cmd, use ssh-keygen to generate some key files.

This should display something like the following (where 'username' is replaced by your user name)

Stopzilla activation key. You can hit Enter to accept the default, or specify a path where you'd like your keys to be generated.At this point, you'll be prompted to use a passphrase to encrypt your private key files.The passphrase works with the key file to provide 2-factor authentication.For this example, we are leaving the passphrase empty.

Now you have a public/private ED25519 key pair(the .pub files are public keys and the rest are private keys):

Remember that private key files are the equivalent of a password should be protected the same way you protect your password.To help with that, use ssh-agent to securely store the private keys within a Windows security context, associated with your Windows login.To do that, start the ssh-agent service as Administrator and use ssh-add to store the private key.

After completing these steps, whenever a private key is needed for authentication from this client, ssh-agent will automatically retrieve the local private key and pass it to your SSH client.

Note

Mar 19, 2019  To enable the machine key works with the form authentication successfully, you may need to keep all the server use the same encryption and decryption key. You may also need to use generate keys button in action panel to generate the key manually, then you need to copy the key to all the server manually. May 13, 2009  IIS 7 Tip # 10 You can generate machine keys from the IIS manager The machineKey element of the ASP.NET web.config specifies the algorithm and keys that ASP.NET will use for encryption. By default the validationKey and the decryptionKey keys are set to AutoGenerate which means the runtime will generate a random key for use. Jul 31, 2012  @Arun – there is no such feature in IIS 6.0 but as that is.NET specific configuration, you can use the same machineKeys created in newer versions of IIS. Simply just create the keys in an IIS 7.x or onwards, then copy the related section to your application's config file, which runs on IIS. Iis machine key validation key generator.

Generate Ssh Key Windows 10 Command Line

It is strongly recommended that you back up your private key to a secure location,then delete it from the local system, after adding it to ssh-agent.The private key cannot be retrieved from the agent.If you lose access to the private key, you would have to create a new key pairand update the public key on all systems you interact with.

Deploying the public key

To use the user key that was created above, the public key needs to be placed on the server into a text file called authorized_keys under usersusername.ssh.The OpenSSH tools include scp, which is a secure file-transfer utility, to help with this.

This example uses the Repair-AuthorizedKeyPermissions function in the OpenSSHUtils module which was previously installed on the host in the instructions above.

These steps complete the configuration required to use key-based authentication with SSH on Windows.After this, the user can connect to the sshd host from any client that has the private key.
