1. A cryptographic system with at least one server and any number of clients, including none, the cryptographic system further comprising:

  • at least one application on one of the at least one server, each capable of engaging in a context-free multi-part communication session with any of the clients;

    a key repository process on one of the at least one server, the key repository process configured to validate and record authorizations of specific programs to access one or more than one set of symmetric keys, wherein each of the at least one application is configured to query the key repository process for one or more than one set of symmetric keys, and the key repository process further configured, in response to the query from a particular instance of the at least one application, to provide the requested one or more than one set of symmetric keys to the particular instance of the at least one application but only if the key repository process authenticates the particular instance of the at least one application as being pre-authorized to receive the requested one or more than one set of symmetric keys;

    wherein, the particular instance of the at least one application can utilize the one or more than one set of symmetric keys for securely off-loading sensitive information in any intermediate part of the context-free multi-part communication session.
