I'm creating an application that uses SQLite (using the SQLite.Net adapter) as its database engine. Since some of the data stored in the database is sensitive I've encrypted the database using the SQLite.NET built-in encryption, and then to open the database I've to do something like this:
vbnet
SQLiteconnection.ConnectionString = "Data Source=" & DataBaseLocation & ";" 'Set the connection string

View 2 RepliesI'm using an MS Access database which has password (database password, not a workgroup or smth). I'm using 13 characters - with no special signs- only letters. When I try to open the DB from access it works fine, but when I try to run my Windows Form application from Visual Studio Connection String, I get a message that "Not a valid password".

I have a chat server / client system running, but I want users to authenticate with my vBulletin forum database.I don't want the client to do it, because it is possible to fake the 'successful login' and connect with a fake username. I want to send the username and password details to the server, and make the server check it with the local vBulletin MySQL database for the username and password.Is there a way to do this? To my knowledge vBulletin has a username and a password entries in the database which is salted, and the salt varies from user to user.
View 7 RepliesI have a document management system, and I am building a Web-Service interfaces to the database.Everything works so far, just that right now, it's totally unsecured, everybody can access it.How can I incorporate password or private-public key authentication?
I can only find 'best practises' and using 'windows user' or passport authentication.But I need authentication from a user and password stored in the database, or better for an RSA private-key stored for each web-service user in the database...
Edit:I have to use the .NET Framework 2.0 in an ASP.NET environment
I am aware of the many cryptography providers that are available in the .NET framework along with the basics of how to use them. This is simple enough.
But my concern is this.Lets say I want to use these libraries to encrypt XML serialized objects to prevent tampering and the ability of anyone to come along and view the contents of these files.
The problem that I am always left with is that the key to decrypt this data would need to be stored as a constant somewhere in my application. Essentially rendering the entire exercise pointless.
So, how does one store a key for an encryption algorithm securely inside of a disassemblable application?
EDIT: So If I am understanding both answers below correctly. What this means is that essentially any implementation (to be secure) requires it to be readonly or writeonly but never both? Is this correct?
In this project, I will develop a dotnet based application which can match and identify the fingerprints and implement the authentication process across ATM usage
