Subject Re: Still stuck with problem. Re: Problem decrypting elements

Thanks, Brent.

Your response identified the problem.  I hadn't added the KeyInfo to each
EncryptedData, but only once.  So, as long as there was only one encrypted
element, it worked but threw an exception if there were more.  Works like a
charm now.

Thanks again,
