Hi,
       I have Created a CRUFL function in C# .This function gets the encrypted item and decrypt it  by using Microsoft Enterprise library algo "RijndaelManaged" its working fine if I have called web.config file by hard coded path using the below code (I am using Crystal Report ver 11.5 and  C# 2.0)

FileConfigurationSource fileSource = new FileConfigurationSource("Web.config file hard coded path");

SymmetricCryptoProviderFactory factory =
                        new SymmetricCryptoProviderFactory(fileSource);

 ISymmetricCryptoProvider provider =
                        factory.Create("RijndaelManaged");

 byte[] encryptedByteArray2 =
                           Convert.FromBase64String(EncryptedText;
 
byte[] unencryptedByteArray2 =
                         provider.Decrypt(encryptedByteArray2);

 string unencryptedText = Encoding.Unicode.
                       GetString(unencryptedByteArray2);

But its unable to find  securityCryptographyConfiguration from web.config file when I'm trying to use (I already have defined that securityCryptographyConfiguration  block in web.config and it's working when I was trying to access web.config file by using hard coded path )

Cryptographer.DecryptSymmetric("RijndaelManaged", EncryptedText)

It gives me the following error (it seems to be that its not able to access web.config in CRUFL function)


System.Configuration.ConfigurationErrorsException: The configuration section securityCryptographyConfiguration is not defined in the current configuration for the AppDomain.
