I'm trying to make a database of MD5 hashes (just for myself). I save the MD5 + Passwords in a .text file. But how can I if the two MD5' are the same, load the password out the .txt file? To read the .txt file I had something like this :

Okay, that's not a big deal... I'll implement FileStreams and read bytes performing operations on them. The problem is that if I do this, the program will hang until the hashes have all been calculated. I want the program to show the hashes calculated so far and a progress bar. I know I need to implement this using threads and interrupts, but how, P.S. Any example code, simply for showing the progress of any operation, and involving a thread,
View 1 Replies`I want to encode my string using .net and pass it to a java program. I am using the same program for encryption and decryption on both the sides. But the java program and .net programs are returning different MD5 hash codes.Here are the codes for both my programs :
VB.net
md5Provider = New MD5CryptoServiceProvider()
input = UTF8Encoding.UTF8.GetBytes(sSecurityKey)
oHash = oMd5CryptoServiceProvider.ComputeHash(input)[code]....
The problem is that m.digest() from java and oHash from vb.net are different. So i cant go further with DES encryption.
I am currently trying to pass an array of objects as a result to VBA but Excel is complaining the following:
'Function or interface marked as restricted, or the function uses an automation type not supported in Visual Basic.'
I have looked around on the internet and have seen similar issues but not to one I am trying to do.
My function is declared as follows:
<ComClass(Class1.ClassId, Class1.InterfaceId, Class1.EventsId)> _
Public Class Class1
#Region "COM GUIDs"

VBA is complaining about the System.Objects my question is how the heck are you supposed to pass and return arrays from .NET to VBA. Also the data that will be in the ArrayRes() is mixed type, its not just strings etc, its an array of arrays that can contain strings, integers doubles etc.
I chose VB .NET because I assumed it would be possible to map to VBA easier.
One last thing, if System.Object and Arrays in VB .NET is not the way, ie maybe theres another way via collections or lists, then Im open to that. I just need to get this data into VBA. Also I could move over to C# if needs be.
I need VB code to compare an input MD5 hash string against a generated string. The generated string is a salted text string plus an integer 1-1000

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.
