The getProvider() method of java.security.Signature class is used to return the provider of this signature object.
Syntax:
public final Provider getProvider()
Return Value: This method returns the provider of this signature object
Below are the examples to illustrate the getProvider() method:
Example 1:
// Java program to demonstrate// getProvider() 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 provider // by using method getProvider() Provider provider = sr.getProvider(); // printing the provider name System.out.println("Provider : " + provider); } catch (NoSuchAlgorithmException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
Provider : SUN version 1.8
Example 2:
// Java program to demonstrate// getProvider() 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 provider // by using method getProvider() Provider provider = sr.getProvider(); // printing the provider name System.out.println("Provider : " + provider); } catch (NoSuchAlgorithmException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
Provider : SUN version 1.8
