Java Signature toString() method with Examples

The toString() method of java.security.Signature class is used to return a string representation of thesignature object, providing information that includes the state of the object and the name of the algorithm used.

Syntax:

public String toString()

Return Value: This method returns a string representation of this signature object.

Below are the examples to illustrate the toString() method:

Example 1:

// Java program to demonstrate
// toString() 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 String representation
            // by using method toString()
            String status = sr.toString();

            // printing the provider name
            System.out.println("Status : " + status);
        }

        catch (NoSuchAlgorithmException e) {

            System.out.println("Exception thrown : " + e);
        }
    }
}

Output:

Status : Signature object: SHA1withDSA

Example 2:

// Java program to demonstrate
// toString() 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 String representation
            // by using method toString()
            String status = sr.toString();

            // printing the provider name
            System.out.println("Status : " + status);
        }

        catch (NoSuchAlgorithmException e) {

            System.out.println("Exception thrown : " + e);
        }
    }
}

Output:

Status : Signature object: NONEwithDSA
