KeyPairGenerator getProvider() method in Java
The provider of the key pair object can be obtained using the getProvider() method in the class java.security.KeyPairGenerator. This method requires no parameters and it returns the provider of the key pair object.A program that demonstrates this is given as follows −Exampleimport java.security.*; import java.util.*; public class Demo { public static void main(String[] argv) { try { KeyPairGenerator kpGenerator = KeyPairGenerator.getInstance("DSA"); Provider p = kpGenerator.getProvider(); System.out.println("The Provider is: " + p.getName()); } catch (NoSuchAlgorithmException e) { ...
