The getAlgorithm() method of java.security.Signature class is used to return the name of the algorithm for this signature object.
Syntax:
public final String getAlgorithm()
Return Value: This method returns the name of the algorithm for this signature object.
Below are the examples to illustrate the getAlgorithm() method:
Example 1:
Java
// Java program to demonstrate// getAlgorithm() methodimport java.security.*;import java.util.*;public class GFG1 { public static void main(String[] argv) { try { // creating the object of Signature Signature sr = Signature.getInstance("SHA1withDSA"); // 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: SHA1withDSA
Example 2:
Java
// Java program to demonstrate// getAlgorithm() methodimport java.security.*;import java.util.*;public class GFG1 { public static void main(String[] argv) { try { // creating the object of Signature Signature sr = Signature.getInstance("NONEwithDSA"); // 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: NONEwithDSA
