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

To set the auto authentication in ssh please follow the steps described below: bash-3.00$ ssh-keygen -t rsa Generating public/private. From the Public key for pasting into OpenSSH authorizedkeys file field at the top of the window, copy all the text (starting with ssh-rsa) to your clipboard by pressing Ctrl-C. You need this key available on your clipboard to paste either into the public key tool in the Control Panel or directly into the authorized keys on your cloud server. I'm trying to set-up SSH connections without password to many servers, using RSA key. It works well for most of them but one is giving me some trouble. The most common issue I've found in the past is permissions problems on.ssh or authorizedkeys on the remote host.

The purpose of ssh-copy-id is to make setting up public key authentication easier. The process is as follows. Generate an SSH Key. With OpenSSH, an SSH key is created using ssh-keygen. In the simplest form, just run ssh-keygen and answer the questions. The following example illustates this. # ssh-keygen Generating public/private rsa key pair. Now generate public and private keys using ssh-keygen on other server. Enter file in which to save the key (//.ssh/idrsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in //.ssh/idrsa. Your public key has been saved in //.ssh/idrsa.pub. I know that you can use ssh-keygen to generate a public/private key pair. Then you can install the public key on a remote server. SSH login without password. Ask Question Asked 8 years, 6 months ago. Browse other questions tagged ssh solaris public-key rsa or ask your own question. Blog Podcast: Don’t Miss Your Stop. Generate an SSH Key Pair on Oracle Solaris. Complete these steps to generate an SSH key pair on UNIX and UNIX-like systems. Run the ssh-keygen command. You can use the -t option to specify the type of key to create. For example, to create an RSA key, type: # ssh-keygen -t rsa. You can also use the -b option to specify the length (bit size) of the key.

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

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.

Generate Ssh Rsa Key Solaris Download

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.

How to Generate a Public/Private Key Pair for Use With Secure Shell

Users must generate a public/private key pair when their site implements host-based authentication or user public-key authentication. For additional options, see the ssh-keygen(1) man page.

Before You Begin

Ask your system administrator whether host-based authentication is configured.

Ssh Rsa Key

1. Start the key generation program.

   where –t is the type of algorithm, either rsa, dsa, or rsa1.

2. Specify the path to the file that will hold the key.

   By default, the file name id_rsa, which represents an RSA v2 key, appears in parentheses. You can select this file by pressing the Return key or provide an alternative file name.

   Parallels 11 key generator download. The file name of the public key is created automatically by appending the string .pub to the name of the private key file.

3. Type a passphrase for using your key.

   This passphrase is used for encrypting your private key. A null entry is strongly discouraged. Note that the passphrase is not displayed when you type it in.

4. Retype the passphrase to confirm it.
5. Check that the path to the key file is correct.

   At this point, you have created a public/private key pair.

6. Log in to the remote host.

   Choose one of the following login steps based on your site's authentication method.

   • For host-based authentication, copy the local host's public key to the remote host.
     1. Type the following command on one line with no backslash.
     2. When you are prompted, supply your login password.

        You can now log in to the remote host. For details, see How to Log In to a Remote Host With Secure Shell.

   • For user authentication with public keys, populate your authorized_keys file on the remote host.
     1. Copy your public key to the remote host.

        Type the following command on one line with no backslash.

     2. When you are prompted, supply your login password.
7. (Optional)Avoid future prompting for passphrases.
