3DES File Encryption (C#)

Image
In cryptography, Triple DES (3DES or TDES) is a symmetric-key block cipher, which applies the DES cipher algorithm three times to each data block.   https://en.wikipedia.org/w/index.php?title=Triple_DES&oldid=995820064  To use 3DES functionality first off all we need to include “System.Security.Cryptography”. using System.Security.Cryptography;   Then we should create and adjust an object which will do encryption: var tdese = TripleDES.Create(); tdese.Mode = CipherMode.ECB; tdese.Padding = PaddingMode.PKCS7; tdese.Key = ConvertHexStringToByteArray( "AABBCCDDEE11223344556677889900FF" ); var encryptor = tdese.CreateEncryptor();  “ConvertHexStringToByteArray” function to convert hex string to byte array: public static byte [] ConvertHexStringToByteArray ( string hexString ) { if (hexString.Length % 2 != 0 ) { throw new ArgumentException(String.Format(CultureInfo.InvariantCulture, "The binary key cannot have an odd number

Arduino Wifi Setup

Image
A IoT device programmed with Arduino need connect to WiFi at start of device to use internet for data transfer etc. First of all we need to include header file “WiFiClient” to our sketch. # include <WiFiClient.h> With code below we will let user enter WiFi credentials over serial communication. we should add this code to our setup() part of our Arduino sketch. Serial . write ( "Please enter name of your wifi network\n" ); while ( Serial . available () == 0 ){}; String Uid= Serial . readStringUntil ( '\n' ); Serial . write ( "Please enter password of your wifi network\n" ); while ( Serial . available () == 0 ){}; String pass= Serial . readStringUntil ( '\n' ); If you want give user a tool to setup WiFi over serial you can download a free serial communication tool “Vengito Serial Tool”. With this tool user can connect IoT device easily and enter WiFi credentials. Download "Vengito Serial Tool"   For more software tools   Af

Monitor Temperature, Humidity, Fire and Smoke of Room

Image
  RoomLog measures ambient temperature and humdity.According to setted min and max values RoomLog sends email (if enabled) and activates 3.3V digital outputs. RoomLog also checks fire and smoke.If RoomLog detects fire or smoke, it sends email and activates 3.3V digital outputs. Monitor ambient temperature and humidity Check fire and smoke around 3.3V Alarm Output for Temp., Humidity, Fire and Smoke Sends Alarm Emails Linux OS Buy Software with Source Code   Buy Software and Device

10 Volt Sensor and Ambient Measurement with 3.3 Volt Alarm Outputs

Image
After calibrating and setting maximum and minimum limits this device gives 3.3V output if limit exceeded. It has 4 sensor connections available and accordingly has four 3.3V digital output connections. Raw sensor value will be multiplied with a constant value and an other constant value will be added to have calibrated value. This calibrated sensor value will be compared with setted limits for decision of 3.3V outputs. • Four ±10V Sensor Input • Four 3.3V Alarm Output • Monitor ambient temperature and humidity • Linux OS Get Software and Source Code   Get Software and Device
