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
