their core, SSH websockets rely on the principles of the SSH protocol, which ensures secure communication over insecure networks. The process of establishing an SSH websocket connection involves several key steps:
Key Exchange and Encryption
When an SSH websocket connection is initiated, the client and server exchange cryptographic keys using a key exchange algorithm. This process ensures that all subsequent communication is encrypted, protecting it from eavesdropping and man-in-the-middle attacks. Commonly used key exchange algorithms include Diffie-Hellman and Elliptic Curve Diffie-Hellman.Once
the keys are exchanged, the connection is secured using encryption algorithms such as AES, 3DES, or Blowfish. These algorithms ensure that data transmitted over the connection remains confidential and cannot be decrypted by unauthorized parties.
Websockets for Real-Time Communication
Websockets are a bidirectional communication protocol that enables real-time data exchange between a client and a server. They allow for continuous, full-duplex communication, making them ideal for applications that require interactive or streaming data transfer.In the context of SSH websockets, the websocket connection is established over the secure SSH tunnel, allowing for real-time communication between the client and server.
This enables applications to send and receive data continuously, facilitating interactive sessions, remote control, and other real-time interactions.
SSH Websocket Security
SSH websockets provide secure communication over websockets, inheriting the security features of SSH and enhancing them with modern web technologies. SSH websockets utilize encryption algorithms, authentication mechanisms, and secure protocols to safeguard data in transit.
