The getProvider() method of java.security.Signature class is used to return the provider of this signature object.
Syntax:
public final Provider getProvider()
Return Value: This method returns the provider of this signature object
Below are the examples to illustrate the getProvider() method:
Example 1:
// 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 Signature
Signature sr = Signature.getInstance( "NONEwithDSA" );
// getting the provider
// by using method getProvider()
Provider provider = sr.getProvider();
// printing the provider name
System.out.println( "Provider : " + provider);
}
catch (NoSuchAlgorithmException e) {
System.out.println( "Exception thrown : " + e);
}
}
} |
Output:
Provider : SUN version 1.8
Example 2:
// 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 Signature
Signature sr = Signature.getInstance( "SHA1withDSA" );
// getting the provider
// by using method getProvider()
Provider provider = sr.getProvider();
// printing the provider name
System.out.println( "Provider : " + provider);
}
catch (NoSuchAlgorithmException e) {
System.out.println( "Exception thrown : " + e);
}
}
} |
Output:
Provider : SUN version 1.8
