By hiding the target hostname from eavesdroppers, ESNI proxy ensures a more confidential and secure communication process.

The Concept of ESNI Proxy

ESNI proxy, a vital advancement in privacy technology, expands on the standard SNI (Server Name Indication) by encrypting the server name. This encryption safeguards the identity of the website the user is visiting, preventing ISPs and malicious actors from tracking or intercepting the request.

  • Traditional SNI: Sends the server name in plain text, accessible to anyone monitoring the connection.
  • ESNI: Encrypts the server name, making it inaccessible to third parties.

  1. Client: Sends encrypted server name requests.
  2. ESNI Proxy Server: Processes the request, decrypts the server name, and forwards it to the intended server.
  3. Intended Server: Responds to the client’s request.

How the ESNI Proxy Works

  1. Client sends an encrypted server name request to the ESNI proxy.
  2. ESNI proxy decrypts the request and forwards it to the intended server.
  3. The server responds to the client via the ESNI proxy.
  4. The client receives the requested information.

Benefits of the ESNI Proxy

  • Enhanced Privacy: Encrypts the server name, keeping it confidential.
