本中文文档详细说明CryptoAPI（一个应用程序编程接口）（带目录方便查询），目的就是提供开发者在Windows 下使用PKI 的编

程接口。CryptoAPI 提供了很多函数，包括编码、解码、加密、解密、哈希、数字证书、

证书管理和证书存储等功能。对于加密和解密，CryptoAPI 同时提供基于会话密钥和公

钥/私钥对的方法。-The Chinese document details CryptoAPI (an application programming interface) (with a convenient directory inquiries), the purpose is to provide developers use PKI in Windows programming interface. CryptoAPI provides many functions, including encoding, decoding, encryption, decryption, hashing, digital certificates, certificate management and certificate storage and other functions. For encryption and decryption, CryptoAPI also provides session-based key and public/private key pair method.
