The getProvider() method of java.security.KeyPairGenerator class is used to return the provider of this key pair generator object.
Syntax:
public final Provider getProvider()
Return Value: This method returns the provider of this key pair generator object.
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 the object of KeyPairGenerator KeyPairGenerator sr = KeyPairGenerator .getInstance("RSA"); // getting the Provider of the KeyPairGenerator 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("Exception thrown : " + e); } }} |
Output:
Provider name : SunRsaSign
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 KeyPairGenerator KeyPairGenerator sr = KeyPairGenerator .getInstance("DiffieHellman"); // getting the Provider of the KeyPairGenerator 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("Exception thrown : " + e); } }} |
Output:
Provider name : SunJCE
