**SSH Key Gen**
After a fresh install we want to generate an SSH key pair (public and private)
we can then use this key to ssh onto hosts without having to share passwords.

On the new host

```
ssh-keygen -t ecdsa
```

you could add a -C for comment and then add your emaiul address but... meh


Example 

```
~$ ssh-keygen -t ecdsa
Generating public/private ecdsa key pair.
Enter file in which to save the key (/home/luddie/.ssh/id_ecdsa):
Created directory '/home/luddie/.ssh'.
Enter passphrase for "/home/luddie/.ssh/id_ecdsa" (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/luddie/.ssh/id_ecdsa
Your public key has been saved in /home/luddie/.ssh/id_ecdsa.pub
The key fingerprint is:
SHA256:gA+5oVKPdtlG7JQC5pL3NQ+OokUK7WoosTevWBCd1E0 luddie@debian-base
The key's randomart image is:
+---[ECDSA 256]---+
|  +. oE          |
| B o.+..         |
|= 1 * X          |
|.O = / =         |
|B = B * S        |
