After selecting signer certificate and (optional) correct password application will display the document to the user. Google for Developers Codelabs provide a guided, tutorial, hands-on coding experience. With properly selected security provider driver and (optional) keystore password user will get a list of available signer certificates In case a driver file is found, application will ask the user to confirm it is correct one and offer him to choose another driver file manually. It will search for drivers in common directories per running operating system. Because of that application might ask the user to confirm usage of suchĮxternal sources, for example Bouncy Castle cryptography library: External sources warning Signer certificate selectionĪpplication will try to find appropriate security provider driver on startup. Thus the application has to be signed with a trusted digital certificate.Īpplication use external libraries and dependencies signed by another vendor. Java (by default) does not allow execution of applications from untrusted sources. When running the application, JRE has to download all required sources from the Internet before starting the application. JNLP stands for "Java Network Launch Protocol". If automatic execution fails, user can start Internet browser will download JNLP file to the local workstation and try to execute automatically. Java application is started from the web browser, by choosing "client" signature option at Signing provider section. Them application requires appropriate drivers installed in the target operating system. Private key and digital certificate that are used for the digital signature are read from USB device. Oracle JRE 8 can be downloadedįrom official Java SE Downloads page. In order to run Java application user must have JRE (Java Runtime Environment) installed on his workstation. Private key holder is an USB device holding multiple private keys and digital certificates that can be used for digital signature. Client software is Java-based application that is downloaded and started on user's demand.
