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.
Apr 11, 2011 In Debian Security Advisory 1571 (New openssl packages fix predictable random number generator), the Debian Security Team disclosed a vulnerability in the openssl package that makes many cryptographic keys that are used for authentication (e.g. Through SSH) or signing (e.g. Web server certificates) potentially vulnerable. Key Rollover. In Debian Security Advisory 1571, the Debian Security Team disclosed a weakness in the random number generator used by OpenSSL on Debian and its derivatives. As a result of this weakness, certain encryption keys are much more common than they should be, such that an attacker could guess the key through a brute-force attack given minimal knowledge of the syst.

Why create a new host key files?
You may need a new key file:
- Your system is compromised.
- Your keys are stolen.
- You forgotten the passphrase.
- Your application need a new host key.
- You can not read the default system key files stored in /etc/ssh/ directory but your non-root application needs key.
- You got an error message which read as “Could not load host key: /etc/ssh/ssh_host_key*”.
ssh-keygen Syntax
The syntax is: /generate-ssh-key-mac-digitalocean.html.
Debian Ssh Host Key Generation Update
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
