Last Updated :
01 Feb, 2023
The getProvider() method of java.security.AlgorithmParameterGenerator class is used to return the provider of this algorithm parameter generator object.
Syntax:
public final Provider getProvider()
Return Value: This method returns the provider of this algorithm parameter generator object.
Below are the examples to illustrate the getProvider() method:
Example 1: For Algorithm DSA
Java
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
AlgorithmParameterGenerator
sr
= AlgorithmParameterGenerator
.getInstance( "DSA" );
sr.init( 1024 );
Provider pro = sr.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 DiffieHellman
Java
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
AlgorithmParameterGenerator
sr
= AlgorithmParameterGenerator
.getInstance( "DiffieHellman" );
sr.init( 1024 );
Provider pro = sr.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 : SunJCE version 1.8
