The service that can describe the implementation of a Provider in regards to any algorithm is obtained using the method getService() in the class java.security.Provider. This method requires two parameters i.e. the service type required and the algorithm name of the required service.A program that demonstrates this is given as follows −Example Live Demoimport java.security.*; import java.util.*; public class Demo {    public static void main(String[] argv) throws Exception {       try {          Signature sign = Signature.getInstance("SHA256withDSA");          Provider p = sign.getProvider();          Provider.Service s = p.getService("Signature", sign.getAlgorithm());   ...

A specific key can be used to search for the required property in the property list using the method getProperty() in the class java.security.Provider. This method requires a single parameter i.e. the key required to search for the property. It returns the property value for the key or returns null if the property value is not available.A program that demonstrates this is given as follows −Example Live Demoimport java.security.*; import java.util.*; public class Demo {    public static void main(String[] argv) throws Exception {       try {          KeyPairGenerator kpGenerator = KeyPairGenerator.getInstance("DSA");         ...
