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
