I'm trying to exchange encrypted data between my ASP.NET application and another developer's CF app using TripleDES. Here's his CF code (fictitious key and IV of course):
<cfset variables.theKey = "rpaSPvIvVLlrcmtzPU9/c67Gkj7yL1S5">
<cfset variables.theIV = BinaryDecode("password","Base64")>
<cfset variables.theAlgorithm = "DESEDE">

What I am attempting to do is pull an encrpted field from my SQL Server (without decrypting on the SQL Server) and decrypting in the VB.NET code itself For example, I created the following symmetric key (in Triple_DES): {This is on a SQL 2005 Server and using a VB.NET 2008 application}
CREATE SYMMETRIC KEY Password_SymmetricKey WITH ALGORITHM = TRIPLE_DES encryption by password = '$MyCompanyKey'

I'm designing a program to encrypt and decrypt files using TripleDes Encryption algorithms but am having issues decrypting an image file. The file encrypts in the correct manner, but when I go to decrypt the file and open as an image I get an error message. One example is when trying to open the file in paint a message appears stating 'c:New FolderDecrypted.jpg Paint cannot read this file. This is not a valid bitmap file, or its format is not currently supported. My coding for the form is shown below:

i am writing a program that will store some passwords in order to make it more user friendly. Ofcourse i want to encrypt it and so i started to learn how to use the 3Des encryption method.

View 5 RepliesI have set up a method in vb.net and in xcode for encrypting a string using as far as i can tell the same parameters for an AES encryption.I've looked all over the place but cannot find information on whether they use the same encryption algorithm and settings.
this is the vb.net code:
Dim encryptAES As New AesCryptoServiceProvider()
Dim encoding As New UTF8Encoding()
Dim encryptor As ICryptoTransform
encryptAES.Key = encoding.GetBytes("12345678901234567890123456789032")
encryptAES.IV = encoding.GetBytes("1234567890123416")
encryptAES.Mode = CipherMode.CBC

There's my code. Now, i want to add a timer, so that my MouseLeave action will delay the "Panel1.Hide" command I'm going to put under it.That way, i can add the Show/Hide commands the the Panel, and there's a much smoother transition.I need help with the timer, I've been playing around with it for a while, and can't get it to work,
i wanted to know what are all the GUI features available in VB.NET for creating a nice UI. The requirement is that, we have screens which were developed in VC++, and now we wanted develop the same screens from scratch, Is it just the way of Drag & Drop all the controls which were present in VC++ screens or something else is available there ?

Hey, im looking for some extension/referenses that can make nice looking charts.
Looking for some that can make similar results as this:
I am trying to use DrawString to write text as an image and then rotate it 90 degrees. It works fine with both a bitmap or directly on a PictureBox, but the big difference is in the quality. The PictureBox text drawn has great quality and looks nice. When I draw it on an image it looks horrible and blocky. I've made a few changes to try and get it to look nicer, but it doesn't look nearly as nice as it should.
Sample code:Use a Windows Forms project and place 2 picture boxes on it and a button and run it with the following code to see what I mean:Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I am trying to build a nice-looking menu that allows users to select certain items. When they hover over the items, a nice highlight color fades in and then out when they leave the item. Anyways, it looks very nice, but I don't want to have to use a "page" style. (e.g., page 1 contains 6 items, click "Next" to go to the next page of 6 itesm) I'd like to allow the user to scroll through the items. I'll develop my own GUI for the scrollbar, however I have absolutely no idea where to start on actually fitting all of the items into like a 400x200 box, and allowing the user to scroll up and down through the items. The items are actual controls (e.g. each item contains a picturebox, a couple of labels, a couple of buttons collectively).

I have been trying to create an app that will do xor encryption. I have tried a few different functions but none of them seem to give me what I want. I need it to put the coded text into a 7 bit ascii string. For example if the key was a - 1100001 and the text to be encrypted was s - 1110011 then it would return 0010010 as the encryption. One of the pieces of code I tried to use
Public Function XOREncryption(ByVal CodeKey As String, ByVal DataIn As String) As String
Dim lonDataPtr As Long
Dim strDataOut As String
Dim temp As Integer

This returns a hex digit though which will not work for what I want.

View 3 RepliesI am attempting to create a program that can do raw RSA encryption (performing the encryption without using 'Encrypt' and 'Decrypt') of a user's message that can contain a-z, A-Z, 0-9, and [,.;:'"()]. I've attached a screen shot of the application form.
Basically, the user will pick from a list of prime numbers from the first box and input them into p and q. They will type their message in the designated textbox and then hit <encrypt> which will encrypt using p and q and then show the encrypted message below. I'll leave out the Key box since that deals with the math behind the encryption.
The part I am stuck on right now is assigning a number to each one of the characters so that it can be encrypted. These numbers need to remain the same so that the message can be decrypted as well.

I'm looking to use RSA Asymmetric encryption to encrypt some data. I've read this article on the forums with a similar title, but it did not answer my question. What I would like to do is use the private key of an RSA key combination to encrypt (sign?) the data and use the public key to decrypt (verify?), as per this wikipedia article . I would like to use this method because I want people to be able to read the data, but not create it themselves. I've copied the code from Peter Bromberg's article RSA Encryption in .NET Demystified , but always get an exception with the "Bad Key" message. If I use the public key for decryption, it works fine (the opposite of what I want). use the public key for encryption.
