[VB.Net]MD5 Encrypter

[-DefaulT]

Very simple, it just runs a timer with an interval of 10ms and auto updates as you type, anything typed into the first text box shows up in the second textbox in md5 encryption.

This is very basic but i use it when adding user accounts to a database so i dont have to go on a web based one where they load it into a database.

Screen shot:

Source:
Form1.vb

Imports System.Security.Cryptography
Imports System.Text

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        TextBox2.Text = MD5(TextBox1.Text)
        Timer1.Interval = "10"
        Timer1.Start()
    End Sub

    Public Function MD5(ByVal Source) As String
        Dim Bytes() As Byte = ASCIIEncoding.ASCII.GetBytes(Source)
        Dim MD5H As New MD5CryptoServiceProvider
        Dim Byt() As Byte = MD5H.ComputeHash(Bytes)
        Dim i As Integer = (Byt.Length * 2 + (Byt.Length / 8))
        Dim StrBuild As StringBuilder = New StringBuilder(i)
        Dim i2 As Integer
        For i2 = 0 To Byt.Length - 1
            StrBuild.Append(BitConverter.ToString(Byt, i2, 1))
        Next i2
        Return StrBuild.ToString().TrimEnd(New Char() {" "c}).ToLower
    End Function

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        TextBox2.Text = MD5(TextBox1.Text)
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Clipboard.SetDataObject(Me.TextBox2.SelectedText)
        Me.TextBox2.SelectAll()
        Me.TextBox2.Copy()
    End Sub
End Class

Woot! Hope you could've done decryptor also

md5 is a one way, you know that right?

[Carrino]

until someone finds out how to decrypt it.

Or you could make a new php file and type in

<?php

echo md5(your words);

?>

saves all the downloading and shit...

[-DefaulT]

yeah but then u have to edit the php file every time u want to encrypt a new word

[s-p-n]

yeah but then u have to edit the php file every time u want to encrypt a new word

<?php
if(isset($_GET['text']))
{
    $md5 = md5($_GET['text']);
    $_GET['text'] = htmlspecialchars($_GET['text']);
    echo $_GET['text'] . ' ~>MD5~> ' . $md5;
} else {
    $_GET['text'] = 'String to convert to MD5';
}
echo '<form action="" method="get">
<input type="text" name="text" value="'.$_GET['text'].'" />
<input type="submit" name="convert" value="Convert to MD5" />
</form>';

myfile.php?text=Hello, World

Good job on the project, but it's pretty pointless.

[-DefaulT]

well its not pointless for me :]

Thanks for the comments though, criticism is always welcome :]

Fine.. I'll just leave this here to show how stupid this is....

HOLY SHIT, ITS MD5!!!

[-DefaulT]

again, at least i dont have to open the website, this sits on my desktop, you can call it pointless all you want but it works for me.

You seem to be afraid of tabbed browsing. It's convenient yo.

And there's no reason you should be calculating MD5s by hand. You're doing something wrong.

nah, i am working on a server emulator, and rather then make a php scirpt to create new accounts for my testers i just add them to the db manually, so i need the md5 for there passwords, this is just easier for me.

See, you're doing it wrong.

Both MySQL (MySQL :: MySQL 5.5 Reference Manual :: 11.13 Encryption and Compression Functions) and MSSQL (HASHBYTES (Transact-SQL)) can calculate MD5s for you.

Stop being noob, thx.
