基于微软CryptoAPI的数字签名和数字信封的实现

Realization of Digital Signature and Digital Envelope based on Microsoft CryptoAPI

针对网络信息安全需求的特点,结合数字签名技术,论文介绍了在Visual C++开发环境下使用微软加密应用程序接口CryptoAPI实现数字签名和验证过程以及数字信封的打包和拆解过程,实际运行表明能够满足网络环境下的保密需求。

In the light of security demand for network information and in combination of digital signature technology, this paper describes the realization of digital signature and its authentication by using Microsoft＇s Encryption Application Program Interface-Crypto API in Visual C＋＋, including the pack and removing of digital envelope. The practical implementation indicates that it can satisfy the security requirement of network environment.
