SecureRandom getAlgorithm() method in Java with Examples

  • Last Updated : 06 Jun, 2021

The getAlgorithm() method of java.security.SecureRandom class is used to return the name of the algorithm implemented by this SecureRandom object.
Syntax: 
 

public String getAlgorithm()

Return Value: This method returns the name of the algorithm or unknown if the algorithm name cannot be determined.
Below are the examples to illustrate the getAlgorithm() method:
Example 1: 
 

Java




// Java program to demonstrate
// getAlgorithm() method
 
import java.security.*;
import java.util.*;
 
public class GFG1 {
    public static void main(String[] argv)
    {
        try {
 
            // creating the object of SecureRandom
            SecureRandom sr = SecureRandom.getInstance("SHA1PRNG");
 
            // getting the Algorithm
            // by using method getAlgorithm()
            String algo = sr.getAlgorithm();
 
            // printing the string algo
            System.out.println("Algorithm: " + algo);
        }
 
        catch (NoSuchAlgorithmException e) {
 
            System.out.println("Exception thrown : " + e);
        }
    }
}
Output: 
Algorithm: SHA1PRNG

 

Example 2: 
 

Java




// Java program to demonstrate
// getAlgorithm() method
 
import java.security.*;
import java.util.*;
 
public class GFG1 {
    public static void main(String[] argv)
    {
        try {
 
            // creating the object of SecureRandom
            SecureRandom sr = SecureRandom.getInstance("TAJMAHAL");
 
            // getting the Algorithm
            // by using method getAlgorithm()
            String algo = sr.getAlgorithm();
 
            // printing the string algo
            System.out.println(algo);
        }
 
        catch (NoSuchAlgorithmException e) {
 
            System.out.println("Exception thrown : " + e);
        }
    }
}
Output: 
Exception thrown : java.security.NoSuchAlgorithmException: TAJMAHAL SecureRandom not available
