Provider.Service getAlgorithm() method in Java with Examples
The getAlgorithm() method of java.security.Provider.Service class is used to return the standard name of the algorithm this Provider.Service is associated with.
Syntax:
public final String getAlgorithm()
Return Value: This method returns name of the algorithm.
Below are the examples to illustrate the getAlgorithm() method:
Example 1:
Java
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
Signature sr
= Signature.getInstance(
"SHA1withDSA" ,
"SUN" );
Provider provider
= sr.getProvider();
Provider.Service service
= provider
.getService( "Signature" ,
sr.getAlgorithm());
String algo = service.getAlgorithm();
System.out.println( "Algorithm : " + algo);
}
catch (NoSuchAlgorithmException e) {
System.out.println( "Exception thrown : " + e);
}
catch (NoSuchProviderException e) {
System.out.println( "Exception thrown : " + e);
}
}
}
|
Output:
Algorithm : SHA1withDSA
Example 2:
Java
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
MessageDigest msd
= MessageDigest.getInstance( "MD5" );
Provider provider = msd.getProvider();
Provider.Service service
= provider
.getService( "MessageDigest" ,
msd.getAlgorithm());
String algo = service.getAlgorithm();
System.out.println( "Algorithm : " + algo);
}
catch (NoSuchAlgorithmException e) {
System.out.println( "Exception thrown : " + e);
}
}
}
