使用数字证书进行PKCS#7数字签名

Making PKCS#7 Digital Signatures with Digital Certificates

越来越多的应用需要使用USB接口数字证书进行PKCS#7数字签名。分别介绍了使用微软CryptoAPI方式和OpenSSL Engine方式进行数字签名。特别提出OpenSSL Engine简化方式,这种方式更为灵活、方便易行。

Making PKCS#7 digital signatures with digital certificates of USB interface is used in more and more applications.This paper introduces two methods of making digital signatures respectively,one uses Microsoft CryptoAPI,the other uses OpenSSL Engine.Especially,this paper presents a third method called simplified OpenSSL Engine method,which is more flexible and feasible compared with the other two methods.
