View 2 RepliesWhat would be the best way of storing data securely away from users. What I have is a stack of files that get downloaded by the program, at the moment they COME encrypted, and stored in a temp location. Now where would be the be place to store them, and how would I store them? The program reads normal unencrypted files but in order for me to open them at the moment I nee to decrypt them in the temp folder and open them from there.This is bad because anyone could find the temp folder and simply copy out all the unencrypted files.Opening the files and then decrypting the bytearray is out of the question because the program only takes a filename as a option.
View 2 RepliesWhat 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.

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 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.
View 4 RepliesI 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?

View 2 RepliesI recently made a small app for a friend and then made it a public app, in doing so I forgot that it connects to my MS SQL DB and checks for values. Someone used Red Gate .Net Reflector to get my password and destroy it all. I've contacted their ISP and they are looking into it, apparently this person has a static ip with them.So this is a lesson learned at a heavy price for me. How can I prevent this from happening again? How can I get away from the unsafe connection string they were able to use?

View 1 RepliesWhat is the best and most secure way to license software? Is there an existing program for doing so? I want to sell a script of mine, but I want to make sure that users cannot redistribute or sell it themselves (of course, if they deactivate the registration on their own computer and choose to resell, that is their choice).
The software language is VB.net.
Since I am not sure whether or not I could host a registration database of any sort, is there any way to keep licensing self-contained securely? I would like the user to be able to download the demo and be able to upgrade to the full version somehow.
I need a bit of advice. I would like to store secure connection strings somewhere safe in vb.net. How can I build the secure connection strings in what situation and what would be the best?

View 2 RepliesI am programming a service for a company that will log valuable performance data on machines that they lease out to other companies. It is critical for them that this information is as safe as possible and that it can only be read by us (a program created by us that is). I already made a trippledes encryptor that works fine but i still have the issue that a person can delete or move or corrupt the file if he somehow manages to get out of the operation software and gain acces to it.So my question is: Can i lockdown a file and make it as good as impossible to change the file or delete it other then by being the admin or the program that is generating them?
View 1 RepliesI am trying to find some source code that is reputable such as code created by Microsoft or a similar entity that has released the source code for AES 128 encryption in the latest VB .net framework. My understanding of encryption methods is sufficient though, I am not an expert on the subject. The following source code [URL] on the MSDN network works very well in VB though with the advent of more secure AES encryption, I would like to be more prudent by using a more secure method. Unless someone can prove or explain that this source code is at a level of a "bank standard encryption" or better I would like to be pointed in the right direction of more secure code or advice from experts.
