Abstract: Methods, systems and computer program products are provided which provide cryptographic services to an application by incorporating in the application an indication of at least one authorized cryptographic function for the application. The indication of at least one authorized cryptographic function for the application is communicated to a cryptographic library that supports a plurality of cryptographic functions. The at least one authorized cryptographic function corresponding to the indication of at least one authorized cryptographic function is then identified as a valid cryptographic function for the application.

Abstract: An enhanced intervention list is used in a data communication network used to route messages from a source or originating user to a destination user in the network. The enhanced intervention list includes an intervention type field which defines how an intercepted distribution is to be processed. For an Associative Redirection intervention type, the message is redirected to a destination user identified in the intervention list. For a Predirecting Intervention type, the message is diverted to an intervening agent or program identified in the intervention list. After the message is processed by the intervening agent, it is routed to a user directory which identifies the destination node serving the destination user. For a Postdirecting Intervention type, the message is sent to the local user directory first and is then checked against the intervention list entries to see if intervention is still warranted.
