Java Signature getProvider Method with Examples

The provider for the signature object can be obtained using the method getProvider() in the class java.security.Signature.

Let us now see an example −

Example

import java.security.*;
import java.util.*;
public class Main {
   public static void main(String[] argv) {
      try {
         Signature signature = Signature.getInstance("SHA256withRSA");
         Provider provider = signature.getProvider();
         System.out.println("The Provider is: " + provider);
      } catch (NoSuchAlgorithmException e) {
         System.out.println("Error!!! NoSuchAlgorithmException");
      }
   }
}

Output

The Provider is: SunRsaSign version 11

Example

Let us now see another example −

import java.security.*;
import java.util.*;
public class Main {
   public static void main(String[] argv) {
      try {
         Signature signature = Signature.getInstance("SHA1withDSA");
         Provider provider = signature.getProvider();
         System.out.println("The Provider is: " + provider);
      } catch (NoSuchAlgorithmException e) {
         System.out.println("Error!!! NoSuchAlgorithmException");
      }
   }
}

Output

The Provider is: SUN version 11
