Method of performing cryptographic functions in a computer application, used in electronic signatures, time stamping etc, uses a cryptographic toolbox which can be used by non-experts in cryptography

摘要

The application (2) is provided with a cryptographic toolbox having a modular architecture (10) consisting of a unit (14) for handling data formats that are used in performing cryptographic functions, with a unit (13) for executing algorithms involved in cryptographic operations, a unit (12) for accessing cryptographic resources and a functional unit (11) which monitors the units used to handle data formats, execute algorithms and access cryptographic resources, the functional unit comprising a functional interface (17) with the rest of the application (16).
