SSH or Secure Shell is a network communication protocol that enables two computers to communicate (c.f http or hypertext transfer protocol, which is the protocol used to transfer hypertext such as web pages) and share data.
SSH (Secure Shell) is a network protocol that enables secure remote connections between two systems. System admins use SSH utilities to manage machines, copy, or move files between systems. Because SSH transmits data over encrypted channels, security is at a high level.
The key difference between SSH vs SSL is that SSH is used for creating a secure tunnel to another computer from which you can issue commands, transfer data, etc. On the other end, SSL is used for securely transferring data between two parties – it does not let you issue commands as you can with SSH.
In Linux, ssh is a protocol, which stands for Secure Shell or Secure Socket Shell. The secure shell is useful for security while connecting to a remote server. The ssh command uses a ssh protocol, which is a secure protocol, as the data transfer between the client and the host takes place in encrypted form.
RDP and SSH are both protocols used for authenticating remote server access. Increasingly, these servers are cloud-based Infrastructure-as-a-Service (IaaS). But both protocols can be used to access servers stored on-prem.
SSH is for securely executing commands on a server. SSL is used for securely communicating personal information. SSH uses a username/password authentication system to establish a secure connection. SSL normally uses X. 509 digital certificates for server and client authentication.
Git used SSH protocol to securely transfer repository data over the internet. Uses public key encryption to secure data. Git with HTTPS uses public-key encryption-based authentication for doing every action like git push, git clone, git fetch and git pull, etc.
So, which one should you use? While SSH is usually considered more secure, for basic usage of Github, HTTPS authentication with a password is acceptable enough. In fact, Github themselves defaults to and recommends most people use HTTPS.
A remote in Git is a common repository that all team members use to exchange their changes. In most cases, such a remote repository is stored on a code hosting service like GitHub or on an internal server. In contrast to a local repository, a remote typically does not provide a file tree of the project's current state.
If you have two-factor authentication enabled, you will have to use a personal access token instead of your regular password. HTTPS works practically everywhere, even in places which block SSH and plain-Git protocols. In some cases, it can even be a little faster than SSH, especially over high-latency connections.
Generate an SSH Key Pair
Upload Your Public Key

The process for creating an SSH key is the same between them.
Steps to copy SSH public key to remote server using ssh-copy-id:
Generating an SSH key
You can start an SSH session in your command prompt by executing ssh user@machine and you will be prompted to enter your password. You can create a Windows Terminal profile that does this on startup by adding the commandline setting to a profile in your settings.
To generate an SSH private/public key pair for your use, you can use the ssh-keygen command-line utility. You can run the ssh-keygen command from the command line to generate an SSH private/public key pair. If you are using Windows, by default you may not have access to the ssh-keygen command.
SSH uses private/public key pairs to protect your communication with the server. SSH passphrases protect your private key from being used by someone who doesn't know the passphrase. Without a passphrase, anyone who gains access to your computer has the potential to copy your private key.
