A method and system for processing enveloped data objects in a data processing system. The enveloped data object may be formatted as defined by PKCS (Public Key Cryptography Standard) standards. An enveloped data object utility allows a user to view and edit the contents of data objects embedded within an enveloped data object via a graphical user interface. Graphical objects represent the data objects embedded within an enveloped data object. A user may drag and drop objects onto other objects within the enveloped data object, and the enveloped data object utility automatically performs the necessary encrypting operations. Logical associations between data objects contained within the enveloped data object are determined or created, and the logical associations are displayed using visual indicators. As data objects are added or deleted through user actions on the graphical objects, the visual indicators are updated.
