What are the functions of the ssh framework?

The Secure Shell (SSH) framework is primarily used for secure data communication and remote operation between remote computers. Its main features include:

  1. Remote login: SSH allows secure access to remote computers through encryption and authentication.
  2. Remote command execution: SSH allows users to execute commands on a remote computer and receive the results of the execution.
  3. File transfer: SSH supports securely transferring files between a local computer and a remote computer.
  4. Port forwarding: SSH enables users to access services on a remote computer from their local computer through a secure tunnel.
  5. SSH can securely display graphical interface applications from a remote computer to a local computer through X11 forwarding.
  6. Public key authentication: SSH supports using public and private key pairs for identity authentication, allowing for a more secure way to log into remote computers.
  7. Session persistence: SSH can automatically restore a session after a network connection is lost to prevent data loss.
  8. Secure Encryption: SSH utilizes both symmetric and asymmetric encryption algorithms to safeguard the confidentiality and integrity of data transmission.
  9. Client-server authentication: SSH supports the authentication between clients and servers to ensure the legitimacy of both parties involved in communication.

Generally speaking, the SSH framework offers a secure and reliable way for remote computer control and data transfer, which can be used for remote management and maintenance of computer systems, as well as securely accessing remote resources.
