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
