Sql Connection String In Web Config File

Windows. Dev. Center. Wei Meng Lee. One of the best practices in ASP. NET is to save your database connection strings in the Web. This allows you to change database servers easily, without needing to modify your code. As an additional protection, it is always better to use integrated Windows security to access your database, rather than using SQL Server authentication, and thus including your SQL server credentials in the connection string. Either way, its not such a good idea to save your connection strings as plain text in Web. In ASP. NET 2. 0, Microsoft has taken this further by allowing you to encrypt the connection strings in Web. Using the Data. Protection. Configuration. Provider and RSAProtected. Configuration. Provider for Encryption. To see how you can encrypt the connection strings stored in the Web. Grid. View control to bind to an Sql. Data. Source control. The connection string used by the Sql. Data. Source control is saved in the Web. You then encrypt the connection strings, using the two Protection Configuration Providers available in. NET 2. 0. 1. Launch Visual Studio 2. Website project. Name the project as C Encrypt. Config. 2.

In particular, ensure that the connection string to the database is stored in Web. Figure 1 Configuring the Grid. View control. The Source View of the Grid. View and Sql. Data.

Section method, unlike Protect. Section, does not require a provider name. When a section is encrypted, information regarding the provider that performed the encryption is stored in the Web. Un. Protect. Section will use that information to determine which provider to use to decrypt the data. There are two protection configuration providers available for your use Data. Protection. Configuration. Provider and RSAProtected. Configuration. Provider. The Data. Protection. Configuration. Provider uses the Windows DPAPI to perform encryption. The RSAProtected. Configuration. Provider uses the public key algorithm available in the. NET Frameworks RSACrypto. Service. Provider class to perform encryption. To test the Encrypt. Conn. Str method, call it in the FormLoad event you should only call the Encypt method once with the indicated Protection Configuration Provider. Protected Sub PageLoadBy. Val sender As Object,. By.
