I used the 'ssh-keygen -t rsa' command to generate keys and copied conte. Stack Exchange Network. Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. In this guide, we’ll focus on setting up SSH keys for a CentOS 8 server. SSH keys provide a straightforward, secure method of logging into your server and are recommended for all users. Step 1 — Creating the RSA Key Pair. The first step is to create a key pair on the client machine (usually your local computer): ssh-keygen. I can generate new dsa, ecdsa and rsa keys using the commands in the article. However, I also find an ed25519 key in /etc/ssh. It was dated the same as the other keys - the data I installed the original OS.
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?
How to generate private key. 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:
Ssh Keygen Centos
Example
Make a dichotomous key generator. Create a host key file in your $HOME/.ssh/myapp as follows. First, create a directory to store your host key file, enter:
To create a host RSAv2 key file, run:
Sample outputs:
$ 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:
Kaspersky internet security activation key. Type the following commands to verify the keys:
Sample outputs:
$ 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
