Oct 24, 2006  First, you will need to generate the local RSA key: # ssh-keygen -t rsa. Next, connect to the remote host through SSH, with the username you used in. Jul 30, 2015 Different SSH programs generate public keys in different ways, but they all generate public keys in a similar format: ssh-rsa or ssh-dss @host Key-Based SSH Logins. Key-based authentication is the most secure of several modes of authentication usable with OpenSSH, such as plain password. You’re looking for a pair of files named something like iddsa or idrsa and a matching file with a.pub extension. 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. When generating SSH authentication keys on a Unix/Linux system with ssh-keygen, you're given the choice of creating a RSA or DSA key pair (using -t type). What is the difference between RSA and DS. Besides allowing the permitted hosts to SSH to the ASA, you need to define RSA keys for the secure connection. In the CLI: crypto key generate rsa. For these key to work, you should have a hostname/domain-name configured on the ASA as well (unless you configure a dedicated RSA keys).

Using a Public/Private key to authenticate when logging into SSH can provide added convenience or added security. The Public/Private key can be used in place of a password so that no username/password is required to connect to the server via SSH. Instead the unique public and private key provide the secure authentication. It is advised that the key uses a different password from your cPanel password.

Generating the Key

1. Login to your Bluehost Control Panel
2. Choose SSH / Shell Access, in the Security section.
3. Click Manage SSH Keys
4. Choose to Generate a new Key
5. Enter a new Key password.
6. Choose DSA or RSA for the type.
   <=' span='> It is recommend that you choose RSA.
7. Choose a Key size, it is recommend to use 2048 or higher.
8. Click Generate Key
9. Click the Go Back button.

Authorize the Key

Authorizing the key will add the public key to the authorized_keys file.

1. Click Manage Authorization
2. Click the Authorize button for your newly created key.
3. Click Go Back to return to the main page.

Private Key

Generating Ssh_host_rsa_key.. No User Exists For Uid

The private key needs to be stored on your local computer.

Generate An Ssh Key

1. To the right of your private key, click View/Download.
2. Click the Download Key button to download the private key.
• If on Linux or Mac OS copy the id_dsa file to your ~/.ssh folder.
• On Windows you will want to move it some place safe.

Using your new key

Windows

For Windows please see Using SSH on Windows (PuTTY)

Linux or Mac OS

1. Open your Terminal
2. Enter the following command

ssh username@IP

3. If you created a passphrase you might see something like the following
Enter passphrase for key '~/.ssh/id_dsa':

After entering the passphrase you will be connected to the server.

How do I create a host key file to use with my applications as I can not use system defined /etc/ssh/ssh_host_rsa_key for non-root account under Linux / Unix / Apple OS X / *BSD operating systems?
You need to use a command called ssh-keygen. This command generates, manages and converts authentication keys for ssh. It can create RSA keys for use by SSH protocol version 1 and RSA or DSA keys for use by SSH protocol version 2. he type of key to be generated is specified with the -t option. If invoked without any arguments, ssh-keygen will generate an RSA key for use in SSH protocol 2 connections. The -f option specifies the filename of the key file.

Generate /etc/ssh/ssh_host_rsa_key

Why create a new host key files?

You may need a new key file:

Ssh Key Rsa Format

1. Your system is compromised.
2. Your keys are stolen.
3. You forgotten the passphrase.
4. Your application need a new host key.
5. You can not read the default system key files stored in /etc/ssh/ directory but your non-root application needs key.
6. You got an error message which read as “Could not load host key: /etc/ssh/ssh_host_key*”.

ssh-keygen Syntax

Generate strong name key file. The syntax is:

Example

Create a host key file in your $HOME/.ssh/myapp as follows. First, create a directory to store your host key file, enter:
$ mkdir -p $HOME/.ssh/myapp
To create a host RSAv2 key file, run:
$ ssh-keygen -t rsa -f $HOME/.ssh/myapp/rsa_key_file
Sample outputs:

Type the following commands to verify the keys:
$ ls -l $HOME/.ssh/myapp/
Sample outputs:

You can now use keys with your app:
$ mycool-app -key $HOME/.ssh/myapp/rsa_key_file -d
