win2000 ipsec 中使用的加密api

CryptoAPI
In addition to Certificate Services, Windows 2000 PKI relies on Microsoft CryptoAPI version 2 for secure cryptographic operations and private key management. CryptoAPI is a Windows 2000 application programming interface (API) that provides cryptographic services for Windows and Windows applications. It provides a set of functions that allow applications to encrypt or digitally sign data flexibly, while providing protection for private keys. Independent modules known as cryptographic service providers (CSPs) perform the actual cryptographic functions.

Developers can use the CryptoAPI to integrate certificate services with existing databases and third-party directory services. Common uses for CryptoAPI include support for customized processes to protect electronic documents.
