【Abstract】 This paper introduces the digital signature and message verification machine based on java, discusses the safe characteristic to the application of java API, because the API can define and gather the usage legal power ,encrypt, safety management and strategy management of the particular resources, and provides some species to manage the public key/private key and notarize the certificate. At the same time, system administrators, developer and user can use the implement that API provides to manage the key storeroom, and use Java to realize the Digital Signature and the flow of verification process.更多还原
