Hi, This is my first tutorial so I hope no one flames me :[
I'll be showing you guys how to add an MD5 Encryption into your project so for those people who use this as a password :
if textbox1.text = "password" then
bla bla

people can easily get your password :P

So to start out you put this at the top most of your form ( any )

Code: Select all

Imports System.Security.Cryptography
Imports System.IO

Then put this right under your Public Class Form

Code: Select all

Public oFile As System.IO.File
    Public password As String = [color=#FF0000]MD5 HASH HERE[/color]  'md5 hash of your password
    Public enteredpassword As String
    Public s As Stream

Now add this function, right under the above code

Code: Select all

Function getMD5Hash(ByVal strToHash As String) As String
        Dim md5Obj As New Security.Cryptography.MD5CryptoServiceProvider
        Dim bytesToHash() As Byte = System.Text.Encoding.ASCII.GetBytes(strToHash)

        bytesToHash = md5Obj.ComputeHash(bytesToHash)

        Dim strResult As String = ""

        For Each b As Byte In bytesToHash
            strResult += b.ToString("x2")
        Next

        Return strResult
    End Function

Now you need to go on google and search for an MD5 encryptor
get the hash and replace the red with your MD5

So here's how you use it

let's say you have a Textbox and a button
the button check to see if the password is correct in textbox1
this is what you would do

enteredpassword = getMD5Hash(Textbox1.Text)
If enteredpassword = password Then
something happens if the password is correct
Else
Something happen when the password is wrong
End If

Thanks for coming :]

You're welcome!
Just remember one thing though, do not give out which site you use to encrypt your MD5 because they can go on it and decrypt it!

unless you make your own MD5 Encryptor

Well ive learnt something new ;)

Good job NoWayIn cooll;

[Nery]

Yes... I didn't know about MD5 Encryption System. Thanks pingpong

[NoWayIn]

Really? I thought you guys would think that this is just some nooby stuffs :P

Actually I've never heard about such thing.
