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
