Security :: MD5 Hash Dropping Zeros?

Apr 23, 2010

I need to pass some info to a 3rd party (for tracking) and they require I provide a checksum value which is an md5 hashed amalgamation of some of the other values. This is my code :

[Code]....

They keep rejecting my checksum. When I have tested for the following value passed in preConvert - 300265215063.79 I get :

My code gives : ED4463C84DE9D21B54C4E62F2D72CE

An online MD5 hash gives : 0ed40463c84de9d21b54c4e62f2d72ce

Which apart from the case, is exactly the same apart from missing 2 zeroes.

Security :: Finding Or Writing Hash Function - Convert Word To Number

Jan 14, 2010

I am tasked with a project to convert words from strings to numbers . I have to do this while ensuring collision-avoidance. i.e training -> 10232323

We are storing the numbers in a database and when we retrieve the records from the database, we will reverse hash and convert the number back to a string
10232323 -> training

As you might have guessed - this is not an area that I am familiar with. I researched the overridable System.Object.GetHashCode() method, but Microsoft warns that there is little guarantee that the default implementation of GetHashCode() avoids collisions.

So I am left stuck. I would like to create an algorithm, but I have no idea where to start.

Also, the function should accept unicode characters - in the event the company decides to internationalize.

SQL Server :: Dropping Primary Key On A Table?

Mar 29, 2011

I am working on a database with about twenty tables. In one of the tables "Customers" their is a column with

a primary key. Call it "CustomerNumber".

The problem is that we log customers from multiple vendors and so we might have the same customer number, but from different vendors. So really this would be a perfect situation where we could set up the primary key to be a composite key consisting of the Vendor and CustomerNumber combination.

The integrity of the database is not very well maintained because the Primary Key CustomerId is never used as a secondary key in any of the other tables.

So here is my question. Instead of making a primary composite key, can I just drop the primary key all together?

This is one of those questions I really hate to ask, because typically I would never lean tword this drastic of a measure to solve a problem. Because of other situations I can't discuss this might be the best alternative. So would it be okay to drop the primary key constraint all together?

Session Variables Are Dropping Within 2 Minutes

Aug 2, 2012

I am currently working on an ASP.NET v4.0 project using VB Script for the server-side code. I have a number of session variables that I am using across multiple pages. My problem is that although I have set the session timeout to be 20 minutes or longer (programmatically, in Web.Config, and IIS), the Session variables are being dumped after exactly 2 minutes.

Web.config contents:

Code:

Session_Start routine:

Code:
Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
' Fires when the session is started
Session.Timeout = 1200 ' Setting to a very high number to ensure that whatever timeout value is set in IIS *should* stick
Session("VariableNames") = VariableValues ' ... multiple values here
End Sub

After exactly 2 minutes (120 seconds) from the last refresh, all the values retrieved using Session("") are blank. Here are a few screen caps to show the IIS settings.

Additionally because of this problem, I have created a generic dummy handle page called KeepSessionAlive.ashx and the following javascript is called using setInterval(KeepSessionAlive, 10000); (every 10 seconds) and I have confirmed that it is working, but the Session variables are still being dumped.

Code:
function KeepSessionAlive() {
//alert('testing');
$.post("KeepSessionAlive.ashx", null, function () {
$("#result").append("
Session is alive
");
});
}

Am I missing something? Why is it dropping my Session values?

Keep Leading Zeros In A OleDbDataAdapter?

Jan 13, 2011

I have understood there is no way to keep leading zeros in a OleDbDataAdapter?

Im trying to read some data from a text file with:

MyCommand = New System.Data.OleDb.OleDbDataAdapter("SELECT F7, F5, F9, F1 FROM " & System.IO.Path.GetFileName(bonnerfil.PostedFile.FileName), MyConnection)

I have managed to keep leading zeros if I add a Schema.ini file into the directory with column set to Char.

But, when having a Shema.ini the select statement reads from start to end of the file. As you see in my select statement I prefer/must have the coulumn 7 first being read and so on. This do work and I will have get the result I want. But for now it´s either - get the order of columns correct or have leading zeros.

how can I either have a Schema.ini that reads the file in the order I want, or keep leading zeros and not have the order I want.

Code:

C# - Random Number Generator Returning Zeros?

Sep 20, 2010

I have an ASP.NET application that relies on the Random class to generate a pseudo-random string. It uses the following code (this is part of a larger piece of sample code provided by Google for apps SSO):

public static class SamlUtility
{
private static Random random = new Random();
private static char[] charMapping = { 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p' };
public static string CreateId()
{
byte[] bytes = new byte[20]; // 160 bits

[Code]...

This normally works very well, but from time to time it starts generating a string of 'a'. From what I can tell from debugging, Random simply stops returning random numbers and instead fills bytes with the same value over and over. I've patched this by using a GUID instead, but I'm curious what happened in the original code. I'm assuming some form of entropy exhaustion, but I can't find any reference in the docs. Also, each time this has happened, performing iisreset restored the correct behavior.

C# - Data Reader Trimming The Leading Zeros?

Jan 13, 2011

I have a string coming from a stored procedure looks like '001234567'.

sqlCommand = new SqlCommand("csp_Bbp_OBN_GetBasePageList", BBConnection);
sqlCommand.CommandType = System.Data.CommandType.StoredProcedure;
sqlCommand.Connection.Open();
// Run the SQL statement, and then get the returned rows to the DataReader.
accReader = sqlCommand.ExecuteReader();............

In my case, from the stored procedure I am returning the varchar, after executing and reading it I am getting the value to basePage.GrouNum which is a string. So, I don't see where it is trimming the leading zeros.

Example: GroupNumber in the table is : "001234567"
BasePage.GroupNum after reading from DataReader : "1234567"

But, I do not want the leading zeros being trimmed.

Forms Data Controls :: Turn Null Cells In A Gridview Into Zeros?

I have a Gridview with some cells in numbers while in some cell they could be null without numbers. I need to modify it such that the numbers in the Gridview are in these formats:-

(a) If it is 12345.333 becomes 12,345

(b) If it is blank, I wish the cells to display 0

This is the code I am using to achieve (a), but when it comes to blank, it returns error (I believe my code below failed to provide blank cases but I dunno how. So what should be the code to do (b) above ?

For i As
Integer = 1
To N

If is there is no SHA-2 implementation some weaker hash funcion would be sufficient. If there are more options I prefer the most secure one.

provide a use example e.g. provide the code that returns one-way hash for string mySampleString.
