ABSTRACT:
A cryptographic services facility uses object-oriented techniques to allow a user to interface with the facility in an algorithm-independent manner. The facility stores algorithm objects which specify algorithm attributes, and context type objects which specify user context attributes such as intended algorithm, intended use, key size and default key. In response to a "create context" request from a user, the context type objects are searched to find a context type that meets the user's requirements, and this is used to create a new context instance. In response to "create context type" requests from the system administrator, a context type factory object searches for an algorithm object that provides a required level of protection and uses this to create a new context type which is then available to users.
