The getProvider() method of java.security.AlgorithmParameters class is used to return the provider of this algorithm parameter object.
Syntax:
public final Provider getProvider()
Return Value: This method returns the provider of this algorithm parameter object.
Below are the examples to illustrate the getProvider() method:
Example 1: For Algorithm DSA
Java
// 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
// AlgorithmParameters
// and getting instance
// using getInstance() method
AlgorithmParameters
sr
= AlgorithmParameters
.getInstance( "DSA" );
// generating the Parameters
// using getProvider() method
Provider pro = sr.getProvider();
// printing the string algo
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 DiffieHellman
Java
// 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
// AlgorithmParameters
// and getting instance
// using getInstance() method
AlgorithmParameters
sr
= AlgorithmParameters
.getInstance( "DiffieHellman" );
// generating the Parameters
// using getProvider() method
Provider pro = sr.getProvider();
// printing the string algo
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: SunJCE version 1.8
