When I clone an OS image to a new, identical hardware PC I of course need to change the host name in a couple of places on the new machine. I suspect it is also good practice to generate new ssh keys for use by openssh server. I found an article here http://www.softec.lu/site/DevelopersCor ... rateNewSsh which outlines the process.
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. Employing my usual monkey see monkey copy/paste/tweak approach I tried the commandThe seems to have worked. It generated keypair files, a fingerprint and a randomart image. The -N and -t parameters seem to be correct according to the man page.
Can anyone confirm that I have supplied all of the necessary inputs to create a valid ed2519 key? Or a way I can test the key for validity?![Centos 7 generate ssh key Centos 7 generate ssh key](/uploads/1/2/6/0/126071029/939461627.png)

How to Generate SSH Keys on PuTTY. SSH keys are one of the most secure SSH authentication options. It is definitely more secure than the usual SSH password authentication. Therefore, it is highly recommended to use SSH Key authentication method for connections to your servers. To create a new key pair, select the type of key to generate from the bottom of the screen (using SSH-2 RSA with 2048 bit key size is good for most people; another good well-known alternative is ECDSA). Then click Generate, and start moving the mouse within the Window. Putty uses mouse movements to.
