Simple Password Encryption Program

Introduction

This article shows you how to make a simple Password encryption Program.

Using the code

The main code used for the conversion is from the Microsoft.VisualBasic class. Below is the code that is used to convert a string to hexadecimal format. We can't direct convert all characters in to hexadecimal format (eg:@#$%^&*()) that's why firstly I take ASCII value of the character, and then convert ASCII value into hexadecimal format.

//For this I made while loop

while (Data.Length > 0)

{

//first I take each character using substring

sValue= Data.Substring(0, 1).ToString()

//then convert character into ascii.

sValue= Strings.Asc(sValue)

//then convert ascii value into Hex Format

sValue = Conversion.Hex(sValue)

//after converting remove the character.

Data = Data.Substring(1, Data.Length - 1);

sHex = sHex + sValue;

}

Ony two functions I used for this application

public string PasswordDecription(ref string Data)

{

string Data1 = "";

string sData = "";

while (Data.Length > 0)

{

Data1 = System.Convert.ToChar(System.Convert.ToUInt32(Data.Substring(0, 2), 16)).ToString();

sData = sData + Data1;

Data = Data.Substring(2, Data.Length - 2);

}

return sData;

}

public string PasswordEncription(ref string Data)

{

string sValue;

string sHex = "";

while (Data.Length > 0)

{

sValue = Conversion.Hex(Strings.Asc(Data.Substring(0, 1).ToString()));

Data = Data.Substring(1, Data.Length - 1);

sHex = sHex + sValue;

}

return sHex;

}
