The getAlgorithm() method of java.security.AlgorithmParameterGenerator class is used to return the standard name of the algorithm this parameter generator is associated with.
Syntax:
public final String getAlgorithm()
Return Value: This method returns the string name of the algorithm.
Below are the examples to illustrate the getAlgorithm() method:
Example 1: For Algorithm DSA
Java
// Java program to demonstrate// getAlgorithm() methodimport java.security.*;import java.util.*;public class GFG1 { public static void main(String[] argv) { try { // creating the object of // AlgorithmParameterGenerator // and getting instance // using getInstance() method AlgorithmParameterGenerator sr = AlgorithmParameterGenerator .getInstance("DSA"); // initializing the AlgorithmParameterGenerator // with 1024 using initialize() method sr.init(1024); // generating the Parameters // using getAlgorithm() method String algo = sr.getAlgorithm(); // printing the string algo System.out.println("Algorithm : " + algo); } catch (NoSuchAlgorithmException e) { System.out.println("Exception thrown : " + e); } catch (ProviderException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
Algorithm : DSA
Example 2: For Algorithm DiffieHellman
Java
// Java program to demonstrate// getAlgorithm() methodimport java.security.*;import java.util.*;public class GFG1 { public static void main(String[] argv) { try { // creating the object of // AlgorithmParameterGenerator // and getting instance // using getInstance() method AlgorithmParameterGenerator sr = AlgorithmParameterGenerator .getInstance("DiffieHellman"); // initializing the AlgorithmParameterGenerator // with 1024 using initialize() method sr.init(1024); // generating the Parameters // using getAlgorithm() method String algo = sr.getAlgorithm(); // printing the string algo System.out.println("Algorithm : " + algo); } catch (NoSuchAlgorithmException e) { System.out.println("Exception thrown : " + e); } catch (ProviderException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
Algorithm : DiffieHellman
