The Computer Security Division's (CSD) Security Technology Group (STG) is involved in the development, maintenance, and promotion of a number of standards and guidance that cover a wide range of cryptographic technology. As it develops new standards, recommendations, and guidance, STG is aiming to develop a comprehensive Cryptographic Toolkit that will enable U.S. Government agencies and others to select cryptographic security components and functionality for protecting their data, communications, and operations. The toolkit currently includes a wide variety of cryptographic algorithms and techniques, and more will be added in the future.
