Create new SSH key for Git/Github

SSHKey.md

To create an SSH key locally:

cd ~/.ssh

# Creates a new pair of SSH keys using elliptic curve called ed25519
# You will have to prompt the path to save the key and a passphrase
ssh-keygen -t ed25519

# Creates a new file called config that will store information about the key and who will access it
# You can use an editor at your choice
nano config

In config file, write the following content:

Host github.com
HostName github.com
User git
IdentityFile $PATH

$PATH is the path where we saved the key.
For instance, $PATH = ~/.ssh/id_github

Close the file. Fetch the content of the generated public key with the following command:

# Fetch the content of public key generated. id_github is the name of the key
cat $KEYNAME.pub

$KEYNAME is the name of the key.
For instance, $KEYNAME = id_github given the path above in IdentityFile attribute of config file.

In the end, add the public key (it is the output of cat command) here.
