This structure of the RSA private key is recommended by the PKCS#1 v1.5 as an alternative ( second) representation. PKCS#1 v2.0 standard excludes e and d exponents from the alternative representation altogether. PKCS#1 v2.1 and v2.2 propose further changes to the alternative representation. After this operation is completed, your key can be found in /.ssh and will be sent in any SSH connections that you make by default. The idrsa file is your private key and should be kept in a safe place. The idrsa.pub file is your public key and can be given to the SingleComm ops team to be installed on any server that you require access to. Sep 26, 2019  Generating an SSH key. To generate an SSH key with PuTTYgen, follow these steps: Open the PuTTYgen program. For Type of key to generate, select SSH-2 RSA. Click the Generate button. Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair. Type a passphrase in the Key passphrase field. As you can see, it’s very easy to generate SSH keys on Windows these days. Basically, the ssh-keygen command does all the work. If you find it difficult to understand how to add the public key to the server, look up your provider’s documentation. They always have a page that describes, in detail, how to do this.

How do I generate ssh RSA keys under Linux operating systems?
You need to use the ssh-keygen command as follows to generate RSA keys (open terminal and type the following command):
ssh-keygen -t rsa
OR
ssh-keygen
Sample outputs:

Ssh Rsa Generate Public Key For Windows

The -t type option specifies the type of key to create. The possible values “rsa” or “dsa” for protocol version 2. The $HOME/.ssh stores the following two files:

• $HOME/.ssh/id_rsa – Your private RSA key
• $HOME/.ssh/id_rsa.pub – Your public RSA key

Please do not share keys file with anyone else. You can upload keys to remote server as follows:
ssh-copy-id userName@server2.nixcraft.net.in
Finally, you can login to remote server as follows:
ssh userName@server2.nixcraft.net.in
scp file.txt userName@server2.nixcraft.net.in:~/data2/

How to Generate a Public/Private KeyPair for Use With Solaris Secure Shell

Users must generate a public/private key pair when their site implementshost-based authentication or user public-key authentication. For additionaloptions, see the ssh-keygen(1) manpage.

Before You Begin

Determine from your system administrator if host-based authenticationis configured.

1. Start the key generation program.

   where -t is the type of algorithm, one of rsa, dsa, or rsa1.

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

   Bydefault, the file name id_rsa, which represents an RSAv2 key, appears in parentheses. You can select this file by pressing the Return key. Or, you can type an alternative file name.

   The file name of the public key is created automatically by appendingthe string .pub to the name of the private key file.

3. Type a passphrase for using your key.

   This passphraseis used for encrypting your private key. A null entry is stronglydiscouraged. Note that the passphrase is not displayed when youtype it in.

4. Retype the passphrase to confirm it.

5. Check the results.

   Check that the path to the keyfile is correct.

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

6. Choose the appropriate option:

   • If your administrator has configuredhost-based authentication, you might need to copy the local host's publickey to the remote host. Generate key file with the keygen.

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

     1. Type the command on one line with no backslash.

     2. When you are prompted, supply your login password.

   • If your site uses user authentication with public keys, populateyour authorized_keys file on the remote host.

     1. Copy your public key to the remote host.

        Type thecommand on one line with no backslash.

     2. When you are prompted, supply your login password.

        Whenthe file is copied, the message “Key copied” is displayed.

7. (Optional) Reduce the prompting for passphrases.

   For a procedure, see How to Reduce Password Prompts in Solaris Secure Shell. For more information, see the ssh-agent(1) and ssh-add(1) man pages.

Example 19–2 Establishing a v1 RSA Key for a User

Ssh Rsa Generate Public Key From Pem

In the following example, the user cancontact hosts that run v1 of the Solaris Secure Shell protocol. To be authenticated by v1hosts, the user creates a v1 key, then copies the public key portion to theremote host.
