Hello, I have setup a form using VS 2010, hosted Windows Server 2008/IIS7, ASP.NET v4. It works perfectly. I have encrypted the web.config file using RSA. When I submit the form I get the error: Parser Error Message: Failed to decrypt using provider 'RsaProtectedConfigurationProvider'. Error message from the provider: Bad Data. Source Error: Line 15: <mailSettings> Line 16: <smtp configProtectionProvider="RsaProtectedConfigurationProvider"> Line 17: <EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element" Line 18: xmlns="http://www.w3.org/2001/04/xmlenc#"> Line 19: <EncryptionMethod Algorithm="http://www.w3.org/ For whatever reason, it does not like line 17. I posted on the ASP.net website as well. I have followed the KB article from DASP on exporting the RSA keys and had them install on the web server. I need help please! Thank you in advance. Jim
