Make Applications More Secure?
Feb 23, 2011
I don't want my programs to be cracked. I have this simple authorization system that prompts my users to enter their forum credentials (I have a forum and the users must be registered members to use the programs).So I made a php script that will take in 3 strings sent in by my applications and it will check against the database if that user exists and is of the proper group and it will display a message on the page and my application then looks for the response in the page source which says if this particular user is allowed to use the program or not.

WinFormsApp Login passes information to .php (server based) Login (provided credentials are correct) to DB to retrieve Decryption Key. WinFormsApp then uses Decryption key on Hardcoded encrypted connection string and renders application usable.This would then eliminate the necessity to encrypt/decrypt a connection string at runtime, virtually rendering any unauthorized person with a useless software.

I have a VB.Net exe application that has a function in it that contains my encryption method that is used through out my application. This function is used to generate all my encrypted passwords and files etc. therefore for obvious reasons I do not want this to be visible to end users. In my application this is fine as it is compiled as a .exe. However I want to now create a ASP.Net web based version of my application.
Now here comes the question, if I was to create a web version of my application then this function would be visible to the end users along with a large number of other functions that if edited could bypass security and license control.I would like to know what is the best way to keep my ASP.Net webbased version secure from tampering, or is ASP.Net not the best for this?

I use several different applications for analysis of pupil data. Each of these applications require similar or identical data but because they don't draw their information from the same sources there is often a need to enter this data more than once which obviously is a waste of time. Some of the data is accessed through the intranet via IE, other applications are standard Windows apps. I would like to create some sort of bridging application to allow data to be automatically shifted from one location to another but have no idea how to use one application to control another
With regard to getting data from the intranet, I have managed to write an application that can retrieve some (but not all) data off a particular page of HTML. It does this by searching the source HTML but some of the data that appears on the page isn't present in the source file. This is very frustrating because I can see it in the browser but can't seem to access it through my application.

I have two web applications that have been migrated over many version of visual studio dating back to 2002 ( I think ).. I'm currently trying to get these applications to act the same in Visual Studio 2010 Premium.App1 - Has designer.vb attached to the pages, and I can see them in the IDE. When I publish the site, it does not want to automatically delete all of the existing files on the target webserver. When I right click -> Properties, a window opens up with lots of web site specific options.. such as Application, Compile, References, Web, Package/Publish Web, Package/Publish SQL, Silverlight Applications.. etc. There is also the option in the right click menu to "Convert to Web Application", which doesn't seem to do anything after the prompt.. and the option for Convert never goes away.
App2 - Does not have designer.vb pages visible in the IDE. When I publish the site, it wants to delete all existing files first.. I'm guessing this is some kind of pre-compile option. When I right click the project -> Properties.. all I see is the smallproperty window, and I don't see any website options like Silverlight or any that App1 gets. There is no 'Convert to Web Application' option.I can not get these two apps to 'act' the same.. and I don't even know which is acting as it should? Both apps work, and publish fine.. they are justing annoying in the IDE that they are so different. What can I do

What is best practice for securing DLL's for projects you are working on? Certain DLL's I am interested in developing will have data access layer (DAL) and business logic layer (BLL) functionality. There may be several apps that can eventually hit these DLL's to perform business specific functions. What is the best way to secure these DLL's so they can only be used by only creator's applications?Security for both blocking unauthorized use of the DLL's and security against possible decompilation are both desirable.

What would be the best way to secure the web service? how do I know if the application requesting the information is who it says it is, and it's not another application that is using another's user name and password?

I'm developing a VB.Net and SQL Server 2005 Express application.Q: How to encrypt string values in the database to secure them from the one using my software and from DBAs (people who have access to the DB Server)? Here is what I tried:First, I used a Symmetric Encryption provided by the .Net Framework. But I noticed that I could not make partial searches (LIKE keyword). So, this is not working.
Then, I used a logic similar to the ROT13 to hide text. Although this logic works fine from VB.Net, once data has been stored in the database, the logic fails to decrypt data correctly. After some tries, I thought that the reason the logic failed was the Collation of the database (I do not know much about Collation topic).So, the first way doesn't allow partial searches, and the second way is not secure and also does not work because of the Collation or maybe another reason.I want to encrypt data. I've successfully hidden the schema by giving meaningless names to tables and columns.

I am interested in making a simple budget program that retrieves current transactions from my bank account and categorizes them appropriately. Is the proper way to do this:
1)Automatically log into the website
2)Read and parse the data
3)Place in correct category?
Is there anything special I would need to do when handling the login/password or should I just do this manually?I'm assuming that is how popular prgrams like Quicken do it.
