Making PKCS#7 digital signatures
with digital certificates of USB interface
【Abstract】Making PKCS#7 signatures with digital certificates of USB interface is used in more and more applications. This
paper introduces two methods of making 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.
【Key words】digital certificates，PKCS#7 digital signatures
