## What is EchidnaTermApp?

This tool is created based on SwiftTermApp to learn cyber security, attack techniques and penetration test.
In addition to the features of SwiftTermApp, the following features from Echidna have been additionally implemented to facilitate learning cyber attack and penetration test techniques.

Some of the features:
Echidna has the following features to assist beginners or teams in conducting penetration testing.
- Target Tree: Echidna extracts command input and outputs and automatically reflects them in the Target Tree.
- Command Suggestion: Suggest candidate commands based on the selected target tree node or current situation and execute them upon clicking.
- Target Graph: Echidna visualizes the target tree in Graph format
- Chat and AI Analysis: Echidna analyzes the terminal outputs with OpenAI in the background and notify a user if Echidna finds some attack path through the Chat component.
- Target Tree Analysis: Analyze Target Tree and highlight it if some critical vulnerabilities are found and display the Machine having the same vulnerability in the Hack The Box.

Unlike Echidna, which is implemented using http as a server-client system, EchidnaTermApp is implemented using ssh and only requires a client.
Because it is client-only, unlike Echidna, it cannot support multiple people working together, but it is lightweight and easy to use.
Unlike Echidna, no setup work is required on Kali Linux; you can use it just by installing EchidnaTermApp on your iPad (Just only starting the ssh service by `sudo systemctl start ssh`).

Since it can be run on an iPad, my goal is to make it possible to casually learn about hacking even when relaxing in the living room or on the sofa, even for students or children.
