Generating Key Pairs For Ssh Login

SiteGround uses key-based authentication for SSH. This has proven more secure over standard username/password authentication. More information on SSH keys can be found here. You can generate an SSH key pair directly in cPanel, or you can generate the keys yourself and just upload the public one in cPanel to use with your hosting account. Ssh-keygen is a tool for creating new authentication key pairs for SSH. Such key pairs are used for automating logins, single sign-on, and for authenticating hosts. The simplest way to generate a key pair is to run ssh-keygen without arguments. In this case, it will prompt for the file in which to store keys. Here's an example: klar (11:39. Using a key pair makes it impossible for someone to log in by using just a password, as long as you set up SSH to deny password-based authentication. This article provides steps for generating RSA keys by using PuTTYgen on Windows for secure SSH authentication with OpenSSH. Generate keys. In Windows, use PuTTYgen to generate your public. Jun 22, 2012  SSH keys provide a more secure way of logging into a server with SSH than using a password alone. While a password can eventually be cracked with a brute force attack, SSH keys are nearly impossible to decipher by brute force alone. Generating a key pair provides you with two long string of characters: a public and a private key. Step ssh login generates a new SSH key pair and send a request to step certificates to sign a user certificate. This certificate will be automatically added to the SSH agent. With a certificate servers may trust only the CA key and verify its signature on a certificate rather than trusting many user keys. POSITIONAL ARGUMENTS identity. 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. Generating a new SSH key.

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.

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:

Generating Key Pairs For Ssh Login In Windows 10

  1. Navigate to your home directory:
  2. Run the ssh-keygen utility, where filename is 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.

  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).
  8. Select all of the characters in the Public key for pasting into OpenSSH authorized_keys file box.

  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.
