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() method import 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); } } } |
Algorithm: SHA1withDSA
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 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); } } } |
Algorithm: NONEwithDSA
