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
