The getProvider() method of java.security.KeyFactory class is used to get the name of the Provider‘s object used by this KeyFactory instance.
Syntax:
public final Provider getProvider()
Parameters: This method does not takes any parameters.
Return Value: This method returns the name of the Provider‘s object used by this KeyFactory instance.
Below are the examples to illustrate the getProvider() method:
Example 1:
// Java program to demonstrate// getProvider() method import java.security.*;import java.util.*; public class GFG1 { public static void main(String[] argv) { try { // creating object of keyfactory KeyFactory keyFactory = KeyFactory.getInstance("DSA"); // getting the Provider // of the KeyFactory keyfactory // by using method getProvider() Provider provider = keyFactory.getProvider(); // printing the provider name System.out.println( "Provider name: " + provider.getName()); } catch (NoSuchAlgorithmException e) { System.out.println(e); } }} |
Output:
Provider name: SUN
Example 2:
// Java program to demonstrate// getProvider() method import java.security.*;import java.util.*; public class GFG1 { public static void main(String[] argv) { try { // creating the object of KeyFactory KeyFactory sr = KeyFactory .getInstance("DiffieHellman"); // getting the Provider of the KeyFactory sr // by using method getProvider() Provider provider = sr.getProvider(); // printing the provider name System.out.println( "Provider name: " + provider.getName()); } catch (NoSuchAlgorithmException e) { System.out.println(e); } }} |
Output:
Provider name: SunJCE
