SSH Secure Shell 3.2.9

SSH stands for Secure Shell. It is a protocol for securely logging into and accessing a remote server or network device over an unsecured network.

SSH Communications Security is a company that develops and markets the SSH protocol implementation known as SSH Secure Shell.

SSH provides secure remote access to servers and network devices. SSH encrypts all data transmitted between the client and server, making it difficult for third parties to intercept or steal sensitive information. SSH supports various authentication methods, including password-based authentication and public key authentication.

SSH is widely supported on various platforms, including Windows, Linux, macOS, and mobile devices.

Public key authentication is a method of authenticating a user to a server using a pair of cryptographic keys. The user stores their private key locally and shares their public key with the server. When the user connects to the server, the server uses the public key to verify the user's identity.

A passphrase is a string of characters used to encrypt and decrypt a user's private key. It acts as an extra layer of protection against unauthorized access to the user's private key.

Port forwarding is a feature of SSH that allows a user to forward network traffic from one port on a local machine to another port on a remote machine. This can be useful for accessing services behind firewalls or NAT devices.

SSH tunneling is a method of creating secure, encrypted connections between two machines over an unsecured network. It can be used for accessing remote services securely or for encrypting other network traffic.

SSH Communications Security offers both free and commercial versions of SSH Secure Shell. The free version has limited features and is intended for personal use.
