The method getProvider() of java.security.MessageDigest class is used to get the provider of this message digest.
Syntax:
public final Provider getProvider()
Return Value: This method returns the provider of this MessageDigest.
Below are the examples to illustrate the getProvider() method:
Example 1: For AlgorithmMD5
Java
// Java program to demonstrate// getProvider() methodimport java.security.*;import java.util.*;public class GFG1 { public static void main(String[] argv) { try { // creating object of MessageDigest MessageDigest msd = MessageDigest.getInstance("MD5"); // getting provider used in object msd // using getProvider() method Provider pro = msd.getProvider(); // display the provider System.out.println("Provider : " + pro); } catch (NoSuchAlgorithmException e) { System.out.println("Exception thrown : " + e); } catch (ProviderException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
Provider : SUN version 1.8
Example 2: For Algorithm SHA-256
Java
// Java program to demonstrate// getProvider() methodimport java.security.*;import java.util.*;public class GFG1 { public static void main(String[] argv) { try { // creating object of MessageDigest MessageDigest msd = MessageDigest.getInstance("SHA-256"); // getting provider used in object msd // using getProvider() method Provider pro = msd.getProvider(); // display the provider System.out.println("Provider : " + pro); } catch (NoSuchAlgorithmException e) { System.out.println("Exception thrown : " + e); } catch (ProviderException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
Provider : SUN version 1.8
