KeyFactory getAlgorithm() method in Java with Examples

Last Updated : 04 Dec, 2018

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 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 algortihm of KeyFactory 
            // using getAlgorithm() method 
            String algo = keyFactory.getAlgorithm(); 
  
            // printing the algorithm 
            System.out.println("Algortihm : " + algo); 
        } 
  
        catch (NoSuchAlgorithmException e) { 
  
            System.out.println("Exception thrown : " + e); 
        } 
        catch (ProviderException e) { 
  
            System.out.println("Exception thrown : " + e); 
        } 
    } 
} 

Output:

Algortihm : DSA

Example 2:

// 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 algortihm of KeyFactory 
            // using getAlgorithm() method 
            String algo = keyFactory.getAlgorithm(); 
  
            // printing the algorithm 
            System.out.println("Algortihm : " + algo); 
        } 
  
        catch (NoSuchAlgorithmException e) { 
  
            System.out.println("Exception thrown : " + e); 
        } 
        catch (ProviderException e) { 
  
            System.out.println("Exception thrown : " + e); 
        } 
    } 
} 

Output:

Algortihm : DiffieHellman
