Last Updated :
19 Jan, 2023
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
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
MessageDigest msd
= MessageDigest.getInstance("MD5");
Provider pro = msd.getProvider();
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
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
MessageDigest msd
= MessageDigest.getInstance("SHA- 256 ");
Provider pro = msd.getProvider();
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
