Setup Github SSH Connection

When pushing or pulling your stuff to and from github it’s prety anoying to have to enter your password. Rescue comes from SSH - the Secure SHell. SSH can use cyptographic keys instead of username+password to authenticate requests. This is how:

Create Key-Pair

$ ssh-keygen -t ed25519 -b 4096 -f ~/.ssh/ed25519_cwa_github -C "CWACoderWithAttitude@gmail.com"
Generating public/private ed25519 key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/pi/.ssh/ed25519_cwa_github
Your public key has been saved in /home/pi/.ssh/ed25519_cwa_github.pub
The key fingerprint is:
SHA256:TjJGkJXK/5ffpmal84Z/ZGx/R6/mICaBzF4Bw7Gtn1c CWACoderWithAttitude@gmail.com
The key's randomart image is:
+--[ED25519 256]--+
|    .+=o         |
|    ..o=         |
|   . .o o        |
|    o+ o .       |
|     .O S   E  . |
|     o.B o .  . *|
|      ..= +..+ =o|
|        .+o.*o+ *|
|         . +oX*oo|
+----[SHA256]-----+

Adding a new SSH key to your GitHub account Copy the contents of your public key file to clipboard a) Either with pbcopy - if available
```
$> pbcopy < ~/.ssh/ed25519_cwa_github.pub
```
or b) open the public key in a text editor like nano or (n)vim or c) cat file to console and copy from there
```
$> $ cat ~/.ssh/ed25519_cwa_github.pub
