What is SSH Tunnel?

SSH tunneling is a method used to transport various types of networking data securely over an encrypted SSH (Secure Shell) connection. This method offers several functionalities:

• Legacy Application Encryption: It enables the addition of encryption to older or legacy applications that may not inherently support secure data transmission.
• VPN Implementation: SSH tunneling can be utilized to create Virtual Private Networks (VPNs), allowing secure access to intranet services even across firewalls.
• Secure Remote Logins and File Transfers: SSH follows a standard protocol for secure remote logins and file transfers over potentially untrusted networks.
• Port Forwarding: SSH facilitates port forwarding, allowing the secure tunneling of TCP/IP ports to ensure the secure transmission of data traffic for any application.

By employing SSH tunneling, the security of data transmitted over the internet is enhanced. Acting as an intermediary between your computer and internet connections, SSH ensures encryption of all transmitted and received data. This encrypted data is then forwarded to another server, enhancing confidentiality and integrity.

It's important to note that while using SSH accounts for tunneling internet connections doesn't guarantee an increase in internet speed, it does offer benefits such as the usage of a static IP address and enhanced privacy.

What is SSH Over SSL/TLS (STunnel)?

SSH Over SSL/TLS (STunnel) encrypts entire connections in SSH over SSL or TLS (Secure Sockets Layer/Transport Layer Security). This method relies on the OpenSSL library to implement the underlying TLS or SSL protocol and is compatible with various operating systems, including most Unix-like operating systems and Windows.
