What is SSH?

Secure Shell (SSH) is a cryptographic network protocol that enables secure communication between two entities over an unsecured network. In simpler terms, it allows you to securely connect to a remote server and perform various tasks, such as transferring files, executing commands, or even accessing graphical interfaces. SSH provides a secure alternative to traditional methods, such as Telnet or FTP, by encrypting all the data that passes between the client (your Macintosh) and the server. This means that even if someone intercepts the communication, they wonโ€™t be able to decipher or tamper with the data. ๐Ÿ›ก๏ธ

How Does SSH for Macintosh Work?

SSH for Macintosh works by establishing a secure connection between your device and the remote server using a pair of cryptographic keys. These keys are generated on both the client and server, and they ensure that only authorized parties can access the server. When you initiate an SSH session from your Macintosh, the client sends its public key to the server, which checks if it matches any of the authorized keys. If a match is found, the server encrypts a random message using the clientโ€™s public key and sends it back. The client then decrypts the message using its private key, proving its identity to the server. Once the identity is verified, the client and server can exchange encrypted data throughout the session. ๐Ÿ”‘
