May 05, 2019  This tutorial explains how to generate SSH keys on Windows with PuTTYgen. We will also show you how to set up an SSH key-based authentication and connect to your remote Linux servers without entering a password. The path to your private key is listed in your site's virtual host file. Navigate to the server block for your site (by default, it's located in the /var/www directory). Open the configuration file for your site and search for sslcertificatekey which will show the path to your private key. Generate a CSR from Windows Server using the certificate MMC Certificate MMC access. Run the MMC either from the start menu or via the run tool accessible fom the WIN+R shortcut. To change the passphrase, click on Load to load an existing key, then enter a new passphrase, and click Save private key to save the private key with the new passphrase. Be sure to properly destroy and wipe the old key file.

  1. How can I find the private key for my SSL certificate. If you just got an issued SSL certificate and are having a hard time finding the corresponding private key, this article can help you to find that one and only key for your certificate.
  2. 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.

Every federation server in an Active Directory Federation Services (AD FS) farm must have access to the private key of the server authentication certificate. If you are implementing a server farm of federation servers or Web servers, you must have a single authentication certificate. This certificate must be issued by an enterprise certification authority (CA), and it must have an exportable private key. The private key of the server authentication certificate must be exportable so that it can be made available to all the servers in the farm.

This same concept is true of federation server proxy farms in the sense that all federation server proxies in a farm must share the private key portion of the same server authentication certificate.

Note Games for windows live product key generator.

The AD FS Management snap-in refers to server authentication certificates for federation servers as service communication certificates.

Depending on which role this computer will play, use this procedure on the federation server computer or federation server proxy computer where you installed the server authentication certificate with the private key. When you finish the procedure, you can then import this certificate on the Default Web Site of each server in the farm. For more information, see Import a Server Authentication Certificate to the Default Web Site.

Membership in Administrators, or equivalent, on the local computer is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups.

To export the private key portion of a server authentication certificate

  1. On the Start screen, typeInternet Information Services (IIS) Manager, and then press ENTER.

  2. In the console tree, click ComputerName.

  3. In the center pane, double-click Server Certificates.

  4. In the center pane, right-click the certificate that you want to export, and then click Export.

  5. In the Export Certificate dialog box, click the button.

  6. In File name, type C:NameofCertificate, and then click Open.

  7. Type a password for the certificate, confirm it, and then click OK.

  8. Validate the success of your export by confirming that the file you specified is created at the specified location.

    Important

    So that this certificate can be imported to the local certificate store on the new server, you must transfer the file to physical media and protect its security during transport to the new server. It is extremely important to guard the security of the private key. If this key is compromised, the security of your entire AD FS deployment (including resources within your organization and in resource partner organizations) is compromised.

  9. Import the exported server authentication certificate into the certificate store on the new server before you install the Federation Service. For information about how to import the certificate, see Import a Server Certificate (http://go.microsoft.com/fwlink/?LinkId=108283).

Several tools exist to generate SSH public/private key pairs. The following sections show how to generate an SSH key pair on UNIX, UNIX-like and Windows platforms.

Windows Server 2008 Generate Private Key

Generating an SSH Key Pair on UNIX and UNIX-Like Platforms Using the ssh-keygen Utility

UNIX and UNIX-like platforms (including Solaris and Linux) include the ssh-keygen utility to generate SSH key pairs.

To generate an SSH key pair on UNIX and UNIX-like platforms using the ssh-keygen utility:
  1. Navigate to your home directory:
  2. Run the ssh-keygen utility, providing as filename your choice of file name for the private key:

    The ssh-keygen utility prompts you for a passphrase for the private key.

  3. Enter a passphrase for the private key, or press Enter to create a private key without a passphrase:

    Note:

    While a passphrase is not required, you should specify one as a security measure to protect the private key from unauthorized use. When you specify a passphrase, a user must enter the passphrase every time the private key is used.

    The ssh-keygen utility prompts you to enter the passphrase again.

  4. Enter the passphrase again, or press Enter again to continue creating a private key without a passphrase:
  5. The ssh-keygen utility displays a message indicating that the private key has been saved as filename and the public key has been saved as filename.pub. It also displays information about the key fingerprint and randomart image.

Generating an SSH Key Pair on Windows Using the PuTTYgen Program

The PuTTYgen program is part of PuTTY, an open source networking client for the Windows platform.

To generate an SSH key pair on Windows using the PuTTYgen program:

Find Windows Server Product Key

  1. Download and install PuTTY or PuTTYgen.

    To download PuTTY or PuTTYgen, go to http://www.putty.org/ and click the You can download PuTTY here link.

  2. Run the PuTTYgen program.
  3. Set the Type of key to generate option to SSH-2 RSA.
  4. In the Number of bits in a generated key box, enter 2048.
  5. Click Generate to generate a public/private key pair.

    As the key is being generated, move the mouse around the blank area as directed.

  6. (Optional) Enter a passphrase for the private key in the Key passphrase box and reenter it in the Confirm passphrase box.

    Note:

    While a passphrase is not required, you should specify one as a security measure to protect the private key from unauthorized use. When you specify a passphrase, a user must enter the passphrase every time the private key is used.

  7. Click Save private key to save the private key to a file. To adhere to file-naming conventions, you should give the private key file an extension of .ppk (PuTTY private key).

    Note:

    The .ppk file extension indicates that the private key is in PuTTY's proprietary format. You must use a key of this format when using PuTTY as your SSH client. It cannot be used with other SSH client tools. Refer to the PuTTY documentation to convert a private key in this format to a different format.
  8. Select all of the characters in the Public key for pasting into OpenSSH authorized_keys file box.

    Make sure you select all the characters, not just the ones you can see in the narrow window. If a scroll bar is next to the characters, you aren't seeing all the characters.

  9. Right-click somewhere in the selected text and select Copy from the menu.
  10. Open a text editor and paste the characters, just as you copied them. Start at the first character in the text editor, and do not insert any line breaks.
  11. Save the text file in the same folder where you saved the private key, using the .pub extension to indicate that the file contains a public key.
  12. If you or others are going to use an SSH client that requires the OpenSSH format for private keys (such as the ssh utility on Linux), export the private key:
    1. On the Conversions menu, choose Export OpenSSH key.
    2. Save the private key in OpenSSH format in the same folder where you saved the private key in .ppk format, using an extension such as .openssh to indicate the file's content.
