, CSPs may encrypt data with special hardware devices (such as smart cards. The CryptoAPI allows simple function calls to encrypt data, exchange public keys, hash a message to create a digest, and generate a digital signature. It also provides advanced management operations, such as using a CSP from a group of possible CSPs. In addition, CryptoAPI provides the foundation for many advanced security services,
