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.

Why create a new host key files?

Generate /etc/ssh/ssh_host_dsa_key

Is it possible to create a relativistic space probe going at least 0.1c with present day technology? Should Word Replacement work on button text? Interview stalled for weeks - how big of a red flag? Can you withdraw the license on an open source project so that even those who already have it. So this more about logging of unnecessary messages in the default configuration. By default, only RSA keys are created and no particular keys are set in sshdconfig so that sshd tries use all 3 types - dsa,rsa, ecdsa - regardless of their existence. 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.

Sep 21, 2011  Generating an SSH keypair. Now you should generate an SSH keypair for each computer that should connect to the server. If that computer runs on Linux, BSD or Mac OS X you can do that directly from that computer. SSH keys are always generated in pairs with one known as the private key and the other as the public key. The private key is known only to you and it should be safely guarded. By contrast, the public key can be shared freely with any SSH server to which you wish to connect.

Generate Ssh_host_dsa_key File

You may need a new key file:

  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

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
