Create Keypair For Github Access

Create a Key for github access

In order to push to github now you have to use a more secure method.

Generate keypair

ssh-keygen -t ed25519 -C "shaunandersonaz@gmail.com"
Generating public/private ed25519 key pair.
Enter file in which to save the key (/home/sanderson/.ssh/id_ed25519): /home/sanderson/.ssh/pc102022
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/sanderson/.ssh/pc102022
Your public key has been saved in /home/sanderson/.ssh/pc102022.pub
The key fingerprint is:
SHA256:<key fingerprint> shaunandersonaz@gmail.com
The key's randomart image is:
+--[ED25519 256]--+
|  Random Art     |
+----[SHA256]-----+

Since we use a passphrase to keep things simple but secure we’ll add this to the ssh-agent.

eval $(ssh-agent -s)
Agent pid 26288

Next add the key to the agent

ssh-add ~/.ssh/pc10202
Enter passphrase for /home/sanderson/.ssh/pc102022: 
Identity added: /home/sanderson/.ssh/pc102022 (shaunandersonaz@gmail.com)

Now we need to add the public key to github. Login to your account and follow the directions here:

You can test your new key by attempting to ssh.

ssh -T git@github.com

Looking for this:

Warning: Permanently added 'github.com' (ED25519) to the list of known hosts.
Hi ShaunAndersonAZ! You've successfully authenticated, but GitHub does not provide shell access.

Need to switch the remote URL. Verify current setting:

git remote -v
origin	https://github.com/ShaunAndersonAZ/ShaunAndersonAZ.github.io.git (fetch)
origin	https://github.com/ShaunAndersonAZ/ShaunAndersonAZ.github.io.git (push)

Change to SSH:

git remote set-url origin git@github.com:ShaunAndersonAZ/ShaunAndersonAZ.github.io.git

Verify change:

git remote -v
origin	git@github.com:ShaunAndersonAZ/ShaunAndersonAZ.github.io.git (fetch)
origin	git@github.com:ShaunAndersonAZ/ShaunAndersonAZ.github.io.git (push)

Now attempt to push:
