KeyFactory getAlgorithm() method in Java with Examples

Last Updated : 24 Jun, 2021

The getAlgorithm() method of java.security.KeyFactory class is used to gets the name of the algorithm associated with this KeyFactory.
Syntax:

public final String getAlgorithm()

Return Value: This method returns the name of the algorithm associated with this KeyFactory.
Below are the examples to illustrate the getAlgorithm() method.
Example 1:

Java

// Java program to demonstrate
// getAlgorithm()  method
 
import java.security.*;
import java.util.*;
import java.security.spec.*;
 
public class GFG1 {
    public static void main(String[] argv) throws Exception
    {
        try {
 
            // creating object of keyfactory
            KeyFactory keyFactory = KeyFactory.getInstance("DSA");
 
            // getting the algorithm of KeyFactory
            // using getAlgorithm() method
            String algo = keyFactory.getAlgorithm();
 
            // printing the algorithm
            System.out.println("Algorithm : " + algo);
        }
 
        catch (NoSuchAlgorithmException e) {
 
            System.out.println("Exception thrown : " + e);
        }
        catch (ProviderException e) {
 
            System.out.println("Exception thrown : " + e);
        }
    }
}

Output

Algorithm : DSA

Example 2:

Java

// Java program to demonstrate
// getAlgorithm()  method
 
import java.security.*;
import java.util.*;
import java.security.spec.*;
 
public class GFG1 {
    public static void main(String[] argv) throws Exception
    {
        try {
 
            // creating object of keyfactory
            KeyFactory keyFactory = KeyFactory
                                        .getInstance("DiffieHellman");
 
            // getting the algorithm of KeyFactory
            // using getAlgorithm() method
            String algo = keyFactory.getAlgorithm();
 
            // printing the algorithm
            System.out.println("Algorithm : " + algo);
        }
 
        catch (NoSuchAlgorithmException e) {
 
            System.out.println("Exception thrown : " + e);
        }
        catch (ProviderException e) {
 
            System.out.println("Exception thrown : " + e);
        }
    }
}

Output

Algorithm : DiffieHellman
