computing hash codes in C# hash codes in C#
Introduction
Here Pawan Kumar will explain how to All in all, computing hash codes in C# is useful across a number of scenarios.
Description
In previous post I have explained Display TextBox when CheckBox is checked in ASP.Net using C#, Get multiple selected (checked) CheckBox values as Comma Separated String using jQuery, How to display values only upto 2 decimal places, Simple way to convert datarow array to datatable, Sending Message Telegram through ASP.NET C#, Open new tab on LinkButton Click using C# and VB.Net in ASP.Net, and many more articles.
Now I will explain How to All in all, computing hash codes in C# is useful across a number of scenarios.
So follow the steps to learn All in all, computing hash codes in C# is useful across a number of scenarios.
Note:- You have to include below two namespace in webform
- using System.Security.Cryptography;
- using System.Text;
Step 1 - Create a asp.net website using Visual Studio 2019 or any other version of visual studio as you have installed on your system.
Step 2 - Add a new Webform C# into the website created in step 1
Step 3 - Drag and drop 2 lables, 1 textbox and 1 button on the webform.
Step 4 - cs.aspx codes are below for Computing hash values in C#
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="cs.aspx.cs" Inherits="examples_2_cs" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<h2>Computing hash values in C# - MD5 with source codes</h2>
<asp:Label ID="Label1" runat="server" Text="Enter text to convert"></asp:Label>
<asp:TextBox ID="tbPlainText" runat="server"></asp:TextBox>
<br />
<asp:Label ID="lblChangedText" runat="server" Text=""></asp:Label>
<br />
<asp:Button ID="btnSubmit" runat="server" Text="Convert to MD5" OnClick="btnSubmit_Click" />
</div>
</form>
</body>
</html>
Step 5: Write the below codes in code behind file of cs.aspx.cs
using System;
using System.Security.Cryptography;
using System.Text;
public partial class examples_2_cs : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
private string MD5(string input)
{
MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
byte[] originalBytes = ASCIIEncoding.Default.GetBytes(input);
byte[] encodedBytes = md5.ComputeHash(originalBytes);
return BitConverter.ToString(encodedBytes).Replace("-", "");
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
lblChangedText.Text= MD5(tbPlainText.Text.Trim());
}
}
Step 6: Now run the project by pressing F5. All in all, computing hash codes in C# is useful across a number of scenarios.
Conclusion:
So, In this tutorial we have learned, All in all, computing hash codes in C# is useful across a number of scenarios.
