Enterprise Library exception: The configuration section securityCryptographyConfiguration is not defined in the current configuration for the AppDomain.

[Jess Chadwick]

I am attempting to use the Enterprise Library (Jan 2006) Cryptography block
to encrypt a credit card number in my ASP.NET 2.0 Commerce Server
application. Everything is configured correctly, as evidenced by the fact
that it is running on a production box using the same web.config (but not
the same parent web.config). When I call the EncryptSymmetric() method, I
get this error:

Server Error in '/Store' Application.
--------------------------------------------------------------------------------

The configuration section securityCryptographyConfiguration is not defined
in the current configuration for the AppDomain.
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code.

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