VS 2008 Decrypting Vbulletin MD5?
Apr 5, 2009
I am trying to setup so a user can subscribe to my forums. When he/she does so, it puts them in the nec. group on the forum. This is all easy. Note: I am the owner of the site and the mysql db. So this isnt to decrypt them on other sites.
In short, all of my software will require a login / password to use the programs.
Now, on the mysql, the db encrypts the passwords. How would I go about decrypting it? I read somewhere that its a one way encryption. If this is the case, how does the site know if the password is right or wrong if it cant decrypt it?

i'm making instead of having the game save as regular text i wanted to mix it up a little. So, i took a bunch of special characters and assigned letters - A-Z and numbers 0-9 - some special characters per character. Anyway, when i 'encrypt'(not really encrypt) the text it works fine. But when i go to change it back.. that's where nothing happens.[code]The code for when i change the regular text into special characters is the same thing except backwards.I would rather not post the project since it's part of an even bigger project.

I have a chat server / client system running, but I want users to authenticate with my vBulletin forum database.I don't want the client to do it, because it is possible to fake the 'successful login' and connect with a fake username. I want to send the username and password details to the server, and make the server check it with the local vBulletin MySQL database for the username and password.Is there a way to do this? To my knowledge vBulletin has a username and a password entries in the database which is salted, and the salt varies from user to user.

I am encrypting a file with this code.
[Code]....
Error #1 Encrypt works but decrypt does not. This is b/c the file extensions in TextBox1.Text is .txt and it is looking for .enc Error #2 If I enter in the file.enc the file will be decrypted but it will have the file extensions .dec. How can I copy the extensions (.txt) and replace the .dec after it was decrypted.

I have a vbulletin forum and want my program users to be able to use their same usernames and passwords they do to login my vbulletin forum. My program is done except for the user authentication. I have searched and googled for weeks now, here is what I know:
� vbulletin 3.8.4 uses, md5(md5($password) . $salt)
� I know how to get the Salt and stored hash from the mysql "user" table.
� I know how to connect to my database without any issues.
I used this code I found here and just modified 3 lines so I could try to get it to work. The code works fine for md5 + salt but as you know I need it to do this: md5(md5($password) . $salt)
Imports System
Imports System.Security.Cryptography
Imports System.Text
Public Class Form1

After I can do this I will be able to code my program to retrieve the users salt and compare the hash to the one stored in my mysql database.

I'm trying to make an authentication before my visual basic 2008 project, a login window. You have to login using your vBulletin username & password. The username and password from my community, which is a vBulletin forum. So, I'd like a form that ask you to login using your username and password from my vBulletin forum, so you'd have to register before...

I've been wondering, how would you make a vBulletin system that checks what users are online and displays them?
I already know how to make a login system, but can't figure this out.

Let's say a create a new project consisting of form1, sized at 400x400.I add a datagridview box of say 350x350 in size.Now that looks fine when the program is run. Except if the user increases the size of the window - or even worse maximises the window on a high res screen. Now my lovely 350x350 datagridview box looks silly on the huge empty background.Is there a way to set the datagridview box to increase in size automatically as the window grows?

I downloaded AxCrypt and encrypted a pdf file. It creates an executable that self decrypts the file if the correct password is entered. This is what I need except that I have to email this self decrypting file - and we all know that exe files get blocked. Are there any self decrypting methods out there that do not use an executable file?

[Code] Here _data is a string containing the encrypted value. m_transformDec is the Decryptor created previously. Usually this works. Occasionally, I get a "bad data" error. I print out the value of _data, and it is always the same. The code is multi-threaded, which I suspect is the reason for both the problem, and it being hard to reproduce. The decryptor is created in the creation of the class, and the decryption is done in a Shared function, but I don't see anything there which is not thread-safe. Any ideas?

I've been messing around with cryptography lately and wanted to figure a way to encrypt an exe so it's not runnable then decrypt it back to it's original state. I found a tutorial online that teaches how to do this with a text file so I figured I'd just tinker with that and try converting it for use with executables. For some reason though after I decrypt the encrypted version it doesn't run and gives me the error:^I'm running 64 bit windows but I'm pretty sure this wouldn't work on an x86 system either.

I have encrypted a user inputted value and successfully stored it in the Windows Registry. Now I am having problems Decrypting that RegistryKey when my Form starts up and making sure it is the same key that was originally stored. My decrypting code has been working but if I go inside the Registry and add an extra character on to that keys value, my program is still running.. It is not supposed to run if that RegistryKey is not the one that was originally user inputted..[code]And I also have tried A LOT of other examples, but I am not going too post them all. So is there anyway I can check if a RegistryKey exists and Decrypt it to make sure that it has not been changed on my programs startup?

Trying to decrypt a textfile is giving me an error: The input is not a valid Base 64-string as it contains a non-Base 64 character, more then two padding characters, or a non-white space character among the padding characters.Besides that I also get an exception while debugging: A first chance exception of type 'System.FormatException' occurred in Fenix.exe When I start the app it opens the file and tries to decrypt it. After decryption the string is send to a label, so I can read it. The codes I used:
vb.net
' encrypt the file Private Function Encrypt(ByVal strText As String, ByVal strEncrKey As String) As String Dim IV() As Byte = {&H12, &H34, &H56, &H78, &H90, &HAB, &HCD, &HEF} Try Dim bykey() As Byte = System.Text.Encoding.UTF8.GetBytes(strEncrKey) Dim InputByteArray() As Byte = System.Text.Encoding.UTF8.GetBytes(strText)

In the UI of my winForm I ask the user for a user name and password. I store this password as text in the Settings (the .settings file) of my project. The app is a visual Studio Add-in How can I encrypt and decrypt the password before and after I enter it into the Settings file? I don't really need anything fancy. It's just a little in-house app. But I'd like to know all my options

I'm calling the following method from a button click event to export a datatable to excel. After the export is completed, the excel application object is quit, released and assigned to nothing. But in reality it's not getting released and stays active unless the entire application is closed. So every time the button is clicked for export, a new excel application object keeps on running. The problem doesn't occur if two of the lines from the method below are not used. But I can't omit them as they are really needed. Check the * marked lines.
Code:
''' <summary>
''' Exports data from a datatable to excel.

i'm running Visual Basic 2008 Express Edition (latest service pack ... 9.0.30729.1 SP) on XP Pro SP3 with .Net Framework version 3.5 SP1 I have a rather large project I've imported from Visual Studio 2003 (Standard).The project compiles and runs just fine ... my compiled program itself never crashes.
But while I actually have the code up in the IDE, and simply adding/deleting code the whole IDE will randomly crash (usually without warning) and I loose my changes since last save.If/when I do get some hint of why it crashed, I get a window about illegal whitespace or something.... but that's rare ... usually it just crashes without warning and the whole IDE completely shuts down instantly. just deleting/adding a character is enough to trigger it maybe once every 30 minutes.
This is on a computer that is otherwise very rock solid .... no other program ever crashes, etc.
