View 2 Repliesi need to implement a standard encryption decryption logic across an entire project platform which has different clients implemented using different platforms as follows:
iphone app (objectiv c)
website (classic asp)
webservice (asp.net)
samsung bada app (c++)
the iphone app as well as the website need to send info to webservice using encrypted query strings
the web service then decrypts this and processes the info further
wanted to know the simplest way to achieve this. is there some free and ready to use binary available with an easy to use api to achieve this?
encryption needs to be as secure as possible
edited: currently we use AES on the website and webservice front

View 1 RepliesThis is meant to be easy ...so ive been told, but still cant get it to work!I have a sql database hosted on a shared server which requires the use of sql authentication.As a result I require to encrypt my sensitive data in the config (connection strings etc).I understand that you can do this using aspnet_regiis etc, but ive been told that as I have no direct acccess to the server, I may need to program the encryption.
I have seen a few examples, but as a novice I have been banging away at this, looking at an errors screen most of the time!
We are designing a .net web application that has an external and internal site.
Both sites need to encrypt data only the internal site needs to decrypt data.
We are wondering what are the best practices for:
Which encryption method to choose?
Where to store the encryption / decryption key?
I used the following command to encrypt my connection string but an error ocurred,
"The connection name'DatabaseConnectionString1' was not found in the applications configuration or the connection string is empty" How can I encrypt it while keeping the application working? What if I move the encrypted application to another computer? Will it work?
I have a Triple DES Key generated by java code from a third party vendor. It is a 3 part key.
We need to use this key in our VB.NET application. When I try to combine this key and use it in my app
'Dim desTransform As ICryptoTransform = desCrypto.CreateEncryptor(EncryptKey(Key), EncryptIV(IV))' gives me an error ' Specified key is not a valid size for this algorithm)
I am new to cryptography and do not understand the algorithms well. How can I use the java generated key in our app for encrypt/decrypt.
I want the encryption and decryption codes in C# for RSA, MD5 and HMAC-SHA1 for generated key.

View 4 RepliesFor our website, we have decided we would like to maintain our user passwords as encrypted binary data in our database. We are using ASP.NET 3.5 to host our site and SQL Server Express 2008 for the database, both running on the same server. When a user logs in and submits a username and password, there will need to be some sort of encryption or decryption in order to verify the credentials. To me, it would appear that there are 3 ways to do this:
1)[C# Encyrption] On User creation, perform encryption in the Web App and submit the encrypted password to the database. To verify credentials at Login, perform the same encryption on the submitted password and ensure that it matches the value stored in the database.
2)[SQL Encryption] On User creation, submit the plain-text password to the database and have it perform one of the SQL encryption variants during INSERT. To verify credentials at Login, have the database perform decryption on the password during the SELECT statement, and compare the plain-text submitted password to the one in the database.
3)[Mix] On User creation, submit the plain-text password to the database, and have it perform one of the SQL encryption variants during INSERT. To verify credentials at Login, perform the same encryption algorithm used by SQL on the submitted password ( is this possible? ), and ensure that it matches the value stored in the database.
Does anybody have an opinion as to which of these options is best? Number 1) is the most familiar to me, and would be the easiest to use with LINQ to SQL ( which is our current data model ), so I am leaning towards that. But if there are better options I would love to know about them.
Not sure if I'm posting the question in the right category.
1) I'm working in a project where encryption of data is high priority. Could some one suggest what would be the best encryption method to protect data from being cracked.
I'm using TCP/IP protocol.
2) Is HTTPS totally secured. If I'm using HTTPS, does that mean that there is no encryption of data required in the coding?
When you need to store sensitive data such as CCs or SSNs, do you:1) Build your own encryption routine within the application, define a secret key somewhere in a config file, and then manually encrypt/decrypt data going to the database.2) Push all the problem to the database, using the built in DB capabilities (I think most vendors call it Transparent Database Encryption).What trade-offs have you find for your solution? Does writing your own routine perform poorly when compared to TDE? Is code maintainability, or conversely DB vendor lock-in an issue?

Someone developed nice HTML pages for a new site. My assignment is to add the code to make the site working with SQLServer.

I have a problem with listview and I can't find any useful solution.
Here is my situation:
I have a listview with insert row and i need to do some calculations as user types in. Some fields are not filled by user but computed by javascript function (they are not inserted into db, they are shown for informational purposes only). These fields are just textboxes - computed ones are disabled. So i want to add some javascript functions to handle the computation, but i need this functions to have proper IDs. So i add them dynamically on listview.itemcreated with attributes.add. And that's where the problem begins.
If I use textbox.attributes.add("onblur", "some code"), suddenly all row commands of insert row stop working. They seem to cause a postback (all filled fields are blank after) but they are not firing any event. ItemCommand, ItemInserted, ItemInserting... Nothing. I have a masterpage and updatepanel in my website but i don't think that is the source of all problems. If I clear all javascript events from all textboxes and dropdownlists, row commands are working again. But I really need some client side computation and validation and I don't know how to make it work and still can insert rows.
Is it possible to declare custom commands within a listview control? For example, if I want to have a "Pay Now" link for each item in the listview, how would I do that?
View 2 RepliesI plan on having multiple Gridviews on one page populated completely in code behind. The only difference between them will be the Stored Procedure. In an effort to save having to write the following for each gridview, can I reuse the commands for each of them. Below is a sample of one of the commands that I would like to use, as well as the bind sub that I am using.
I realize that it will not be at all difficult to cut and paste each of these lines, and making the minor edits for each one. I just would like to keep my code behind file thin, as well as only limiting the chance for mistakes by using multiple commands.

How do i run a shell command in asp.net ?

I've been trying to use the same SqlConnection and SqlCommand objects to execute to different commands.
the first one checks for duplicate and the second one inserts the data if the data the user entered is not a duplicate.
Here's a sample of my code:
using (SqlConnection conn = new SqlConnection(ConnStr))
{
string Command = "SELECT CountryName FROM [Countries] WHERE CountryName = @Name";
using (SqlCommand comm = new SqlCommand(Command, conn))
{
comm.Parameters.Add("@Name", System.Data.SqlDbType.NVarChar, 20);
comm.Parameters["@Name"].Value = Name;
comm.Parameters.Add("@IsVisible", System.Data.SqlDbType.Bit);
comm.Parameters["@IsVisible"].Value = IsVisible;
conn.Open();
if (comm.ExecuteScalar() == null)
{
Command = "INSERT INTO [Countries] (CountryName, IsVisible) VALUES (@Name, @IsVisible);";
comm.ExecuteNonQuery();
}
}
I was trying to save a trip to the database by using one connection.
The Problem is:
The first command runs okay but the second command which inserts into the database won't work (it doesn't add any records to the db) and when I tried to display the rows affected it gave me -1 !!
The Question is:
Is this is the ideal way to check for a duplicate records to constraint a unique country ? and why the second command is not executing ?
