Store An Encrypted Password Into A Database?
Oct 17, 2010
I need to be able to accept a password from a user in a WPF app, encrypt it then store this in a database and be able to decrypt later on. However I'm not sure how to implement this.
This is completely trivial so whether it's safe or not doesn't matter. All I need is for it to get working only I'm unsure exactly how to do it. I've tried playing around with the DESCryptoServiceProvider() but haven't gotten anywhere.
To be clear, how exactly do I go about converting a simple password into something that's been encrypted and storing it in the database (and what fields would I store it in). At this point, I'm happy if there's only one key and that key is being defined in the source code.

I use AES encryption in my vb.net 2008 windows forms apps to ....
1. Store user passwords in sql server express database in encrypted form
2. decrypt the encrypted Sql server express connection string password on the fly when connecting to SQl Server over a vpn or direct to web based sql server database
3. decrypt the encrypted ftp site password on the fly when my application connects to my ftp site to upload client's database backups
The issue I have is that the secret key for the encryption / decryption is hard coded within the encryption/decryption functions. So anybody who decompiled my application would be able to generate the same encryption, as they would have the encryption secret key How can you hide the encryption secret key so that if anybody decompiled my app they could not reproduce the decryption function

I'm a newbie in visual basic. I'm doing a login system. I'm done with the GUI. but for the programming part, I want to know where to store new user's information along with the username and password. I've done research. seems like it has something to do with database. p/s: I'm looking for high security in storing data to prevent hacking.

I am attempting to find some code to use in VB.NET to decrypt a string that has been encrypted using the Java crypto libary.All of the code I have found so far uses an Initialisation Vector and Key to decrypt but the string has been encrypted using the Key only. (Using an Initialisation Vector is apperently an optional step in Java).Does anyone know of code that I can use (preferably in VB.NET but i could convert C#) to decrypt AES 128 Bit encoded string without an Initialisation Vector?

I went for an interview last week, and the interviewer asked me a question that i failed to answer.
He asked me, how did i store the password in the database. Then i answered that i would encrypt it then store it in database.
Then he said after encryption, developer or admin still able to view the encrypted password. But he didn't want developer or admin to be able to view the encrypted password.
I thought of cookies, but if user clear their cookies file, everything will be gone.

As we pass data to a database in a clear cut way, there may be situations, when we might fear data stealing. So can we simply encrypt data at the time of insertion, so that the data privacy will be maintained and the front end can only see the data.

I have the following code which extracts the contactcode from a table in a database;
[Code]...
Code: lblUniqueID.Value() = (RandomPassword.Generate(4, 6)) Now, I want to compare the contactcode values extracted from the database and the value stored in lblUniqueID.Value(). If the random password is similar to one of the contactcode then generate another RandomPassword IF NOT then place the value to another label called lbltransfer.text.
I'll insert that value to the database.. The idea is extract all the contactcodes(these are the random passwords already generated and stored) from the database. Compare with the new generated password if it exists then create another one if not then store it in a label called lbltransfer.text.

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()

I use VB.NET 2010 Express and Windows 7. Access is not installed.The code used to connect database password protected, is:
Public Class Form1
Dim cn As OleDb.OleDbConnection

The code is not working. I get this error: "Could not find installable ISAM".
