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

Sshhostrsakey.pub — SSHプロトコルのバージョン2のsshdで使用する RSA公開鍵。ユーザー固有のSSH設定情報は、ユーザーのホームディレクトリ内の /.ssh/ ディレクトリに格納されます：.
And then I deleted the sshhostrsakey.pub. That didn't work. I rebuilt the host keys, undid the configuration change, left my generated public key in the home directory, and moved the generated private key to the client. The connection works great, and the fingerprint OS X (my client) prompts me with matches the sshhostrsakey.pub.
If you look in the /etc/ssh/ directory of most (or all) linux/bsd ssh servers you see 3 public keys: sshhostdsakey.pub sshhostkey.pub sshhostrsakey.pub I know that the dsa and rsa are for. But I don't understand what sshhostkey.pub is for. Obviously it's the public key for the private key sshhostkey.

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.

Dec 15, 2018 ssh-keygen-t ed25519-f / etc / ssh / sshhosted25519key-N ' Remove Small Diffie-Hellman Moduli If you use the RSA method, we want to make sure it doesn’t do a DH handshake with a weak key, so remove any weak keys. Dec 23, 2019 You’ll find a file named sshhostrsakey-cert.pub in your current directory, which you should copy back to the server. Because sshd(8) doesn’t look for host certificates by default, you shold edit /etc/ssh/sshdconfig to instruct it to do so. Add this line to the file to let it work. The basic format of the command to sign user's public key to create a user certificate is as follows: ssh-keygen -s causerkey -I certificateID idrsa.pub Where -s indicates the private key used to sign the certificate, -I indicates an identity string, the certificateID, which can be any alpha numeric value.It is stored as a zero terminated string in the certificate.

Before You Begin

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

Start the key generation program.
where –t is the type of algorithm, either rsa, dsa, or rsa1.
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.
The file name of the public key is created automatically by appending the string .pub to the name of the private key file.
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.
Retype the passphrase to confirm it.
Check that the path to the key file is correct.
At this point, you have created a public/private key pair.
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.
(Optional)Avoid future prompting for passphrases.
