SSH
SSH, which stands for Secure Shell, is a cryptographic network protocol used for secure communication over an unsecured network. It is commonly used to access and manage remote systems securely.
SSH provides a secure channel over an insecure network by using strong encryption to protect the communication between a client and a server, preventing eavesdropping, connection hijacking, and other attacks.
SSH key
An SSH key is a pair of cryptographic keys used for secure communication between a client and a server using the SSH (Secure Shell) protocol. The two components of an SSH key pair are the private key and the public key.
Using SSH keys for authentication is considered more secure than traditional password-based authentication. The private key acts as a form of digital signature, and even if someone gains access to the public key, they cannot easily derive the corresponding private key.

Solution
Check your OS
This step is just to make sure you have Linux Mint or a Ubuntu-based Linux distribution.
cat /etc/os-release
lsb_release -a
uname -a
hostnamectl
Output
List all SSH keys
ls ~/.ssh/
Generate the SSH key
ssh-keygen -t ed25519 -C "Pro Bug Hunter Mint SSH Key" -f ~/.ssh/pbh_mint_ssh_key
Output
Brief explanation
-t ed25519: The-tflag stands for type. It specifies the type of key to create, in this case, Ed25519.-C "Pro Bug Hunter Mint SSH Key":-Cstands for comment. It adds a comment to the key. Make sure to include the comment in double quotes.-f ~/.ssh/ebh_fedora_ssh_key:-fstands for filename. It specifies the filename of the key.
Enter your passphrase
Leave empty if you prefer.
Visualize your key
List your keys
ls ~/.ssh/
Output
Done
Celebrate
Well-done. You did a great job!
