+Summary: SMS gateway using an Android phone
+Home-page: UNKNOWN

+License: UNKNOWN
+Description: # Termux Sms Gateway
+        SMS and notification gateway using Android smartphone
+        
+        #### Goal:
+        
+        Make any laptop with an Internet connection a SMS gateway
+        Send SMS from his desktop using a web interface or other.
+        Receive SMS on his desk in order to use the content.
+        
+        #### Method used
+        
+        - SMS sending
+        
+        - SMS are created on one machine (1 or more) on the network.
+            - They are then published to a public or private MQTT server
+            - The messages are received on an MQTT client installed on the laptop (1 or more).
+            - The messages are then sent to the recipients.
+        
+        #### SMS reception
+        
+        - The SMS are received on the smartphone and published to the MQTT server
+        - The messages are received on a MQTT client installed on the subscribed machine (1 or more)
+        
+        #### Non-exhaustive use
+        
+        - Email message usage
+        - Receive and process alert messages (IOT or other)
+        - etc ...
+        
+        #### Conditions for receiving or sending
+        - Take a public or private MQTT server to relay messages
+        - Subscribe MQTT customers to the same topics
+        
+        > You can install your own mosquitto server
+        >> https://mosquitto.org/download/
+        >
+        > More information on MQTT: https://fr.wikipedia.org/wiki/MQTT
+        
+        - Security of data transmitted
+        > We may need to encrypt the content for security reasons.
+        >> Use encryption with public key / private key on clients
+        
+        ### Smartphone installation
+        
+        https://github.com/termux/termux-app
+        
+        #### Installation of termux
+        - Termux application obtained by F-Droid:
+            - https://www.f-droid.org/fr/
+        
+        - Or by google store:
+            - https://play.google.com/
+        
+        > IMPORTANT: We will choose either one or the other.
+        
+        - Install
+            - Termux
+            - Termux: API
+            - Termux: Widget
+        
+        
+        #### Installing the mqtt client:
+        
+        The following python packages will be installed:
+        
+        - termux-sms-gateway
+        - paho-mqtt
+        - supervisor
+        	- supervisor is a process control system
+        	- because Android do not support hard links, it will be necessary to patch  http.py from library
+        - rsa >> https://stuvel.eu/python-rsa-doc/
+        
+        ### Installation procedure
+        
+        After installing termux on the smartphone, launch Termux
+        
+        - Copy and paste the following command in the terminal
+        
+                export PACKAGE="TermuxSmsGateway"&&
+        		export VERSION="1.0"&&
+        		mkdir -p $HOME/.termux/tasks&&
+                apt install python git termux-api -y&&
