All settings on this page only affect Quick Encryption and Quick Decryption, not the normal wizards. Here you can select what you want to encrypt - the whole document, a selection or a document fragment identified by an XPath expression. The encryption type is fixed to Enveloping at the moment. Select the algorithms to use and provide a keystore containing a key which match those algorithms. Chose the encryption id carefully. Quick Decryption searches for this id, so it should be unique.
