SSH (Secure Shell)

SSH (Secure Shell) is a cryptographic network protocol used to secure communications over an unsecured network. It provides a secure channel over an otherwise insecure network by employing encryption and authentication techniques. SSH is commonly used for securely accessing remote servers, managing network infrastructure, and executing commands. It ensures that data transmitted between the client and server is encrypted, making it resistant to eavesdropping, tampering, and forgery. SSH can also facilitate secure file transfers and is essential for maintaining the confidentiality and integrity of data exchanges. By leveraging public-key cryptography, SSH offers robust security features, including strong encryption and user authentication.
