KeyPairGenerator getProvider() method in Java with Examples

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
