    How to set up SSH key authentication in Linux system
    SSH (SecureShell) is an encrypted network protocol that is widely used to run network services securely on insecure networks. SSH provides encrypted communication and authentication methods, which makes data transmission more secure and reliable. SSH key authentication is a more secure authentication method and is recommended over traditional password authentication. In terms of security, SSH key authentication provides a higher level of protection because it is based on an encryption mechanism of public and private keys, effectively reducing the risk of password cracking. Password authentication is not very secure in many cases, as passwords can be guessed, cracked, or even compromised by man-in-the-middle attacks during transmission. This emphasizes the use of more complex and multi-layered
