Encrypting Connection Strings in web. Introduction. ASP. NET stores all the configuration information in plain text files called web. We store all vital information including database connection strings, user names, passwords for the databases. Thus you end up storing all sensitive information in vulnerable plain text files which is nothing but security compromise. Taking a clue, Microsoft has provided the capability to encrypt sensitive information in configuration files. ASP. NET 2. 0. With this new capability you can easily encrypt sections of configuration files which makes your application secure. ASP. NET is a technology for developing, deploying, and running Web applications and it is a part of the Microsoft. NET Framework. You can use this script to do Insert a binary or text file to a field of a SQL table using binary hex conversion. Convert a file to a Hex String base16, RFC3548. Im trying to set up a connecting string in my web. Visual Studio 2008ASP. NET 3. 5 to a local server SQL server 2008. In my web. config, how and where. Note. You can save part of a connection string in a configuration file and use the DbConnectionStringBuilder class to complete it at run time. This is useful in. This new capability brings it with performance overhead. So use it sparingly. That means be judgmental and judicious when you decide to encrypt data. Connection String Text File Asp' title='Connection String Text File Asp' />ASP. NET 2. 0 introduced Protected Configuration model that allows you to encrypt data using. Protected Configuration Providers. They are RSAProtected. Configuration. Provider This is the default provider and uses.

Add new form to your existing project and add the below method Encrypt. Conn. String. to code behind of the form. We will use RSAProtected. Configuration. Provider model to encrypt the connection strings. We will try to analyze this magic piece of code. Lets start with namespaces. The System. configuration namespace contains classes which deal with the configuration information. ASP. NET applications. The System. Web. Configuration. Web. Configuration. Manager class is the preferred way to provide programmatic access. ASP. NET web applications. You can use one of open methods provided by Web. Configuration. Manager that return configuration object. The Get. Section method of configuration object returns the connection. Strings section object for the web. System. Web. Configuration. System. Web. Security. System. Configuration. Encrypt. Conn.
