基于PKI的数字签名和数字信封的实现

Realization of digital signature and digital envelop based on PKI

针对网络信息安全需求的特点,利用PKI(Public Key Infrastructure公钥基础设施)技术,以Windows2000为平台,在Visual Basic 6.0开发环境下,使用加密应用程序接口CrytoAPI和CAPICOM,实现对信息传输过程中数据的数字签名和数字信封工作,详细介绍了数字签名的签名和认证过程,以及数字信封的打包和拆解过程,实际运行表明可以满足网络环境下的保密要求。

By using PKI (Public Key Infrastructure), the encryption Application Program Interface-CrytoAPI and CAPICOM are applied to realize the digital signature and the digital envelop for information transmission. The signature and authentication of digital signature and the pack and removing of digital envelop are discussed. The practice indicates that it can meet the requirements of network environment.
