Explanation
You encrypt and decrypt the contents of a Web.config file by using System.Configuration . DPAPIProtectedConfigurationProvider, which uses the Windows Data Protection API (DPAPI) to encrypt and decrypt data, or System.Configuration. RSAProtectedConfigurationProvider, which uses the RSA encryption algorithm to encrypt and decrypt data. When you use the same encrypted configuration file on many computers in a Web farm, only System.Configuration.RSAProtectedConfigurationProvider enables you to export the encryption keys that encrypt the data and import them on another server.
