Java Signature getProvider() method with Examples

Last Updated : 4 Dec, 2018
The getProvider() method of java.security.Signature class is used to return the provider of this signature object. Syntax: 
public final Provider getProvider()
Return Value: This method returns the provider of this signature object Below are the examples to illustrate the getProvider() method: Example 1: Java 
// 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 Signature
            Signature sr = Signature.getInstance("NONEwithDSA");

            // getting the provider
            // by using method getProvider()
            Provider provider = sr.getProvider();

            // printing the provider name
            System.out.println("Provider : " + provider);
        }

        catch (NoSuchAlgorithmException e) {

            System.out.println("Exception thrown : " + e);
        }
    }
}
Output: 
Provider : SUN version 1.8
Example 2: Java 
// 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 Signature
            Signature sr = Signature.getInstance("SHA1withDSA");

            // getting the provider
            // by using method getProvider()
            Provider provider = sr.getProvider();

            // printing the provider name
            System.out.println("Provider : " + provider);
        }

        catch (NoSuchAlgorithmException e) {

            System.out.println("Exception thrown : " + e);
        }
    }
}
Output: 
Provider : SUN version 1.8
