KeyPairGenerator getAlgorithm() method in Java with Examples Last Updated : 01 Feb, 2023 Summarize Comments Improve Suggest changes Share Like Article Like Report The getAlgorithm() method of java.security.KeyPairGenerator class is used to return the standard name of the algorithm for this key pair generator. See the KeyPairGenerator section in the Java Cryptography Architecture Standard Algorithm Name Documentation for information about standard algorithm names.Syntax: public String getAlgorithm() Return Value: This method returns the standard string name of the algorithm.Below are the examples to illustrate the getAlgorithm() methodExample 1: Java // Java program to demonstrate // getAlgorithm() method import java.security.*; import java.util.*; public class GFG1 { public static void main(String[] argv) throws Exception { try { // creating the object of KeyPairGenerator KeyPairGenerator kpg = KeyPairGenerator .getInstance("RSA"); // fetching the Algorithm // using getAlgorithm() method String algo = kpg.getAlgorithm(); // printing the string algo System.out.println("Algorithm : " + algo); } catch (NoSuchAlgorithmException e) { System.out.println("Exception thrown : " + e); } } } Output: Algorithm : RSA Example 2: Java // Java program to demonstrate // getAlgorithm() method import java.security.*; import java.util.*; public class GFG1 { public static void main(String[] argv) throws Exception { try { // creating the object of KeyPairGenerator KeyPairGenerator kpg = KeyPairGenerator .getInstance("DiffieHellman"); // fetching the Algorithm // using getAlgorithm() method String algo = kpg.getAlgorithm(); // printing the string algo System.out.println("Algorithm : " + algo); } catch (NoSuchAlgorithmException e) { System.out.println("Exception thrown : " + e); } } } Output: Algorithm : DiffieHellman Comment More infoAdvertise with us Next Article KeyPairGenerator getProvider() method in Java with Examples R rohitprasad3 Follow Improve Article Tags : Misc Java Java-Functions Java-security package Java-KeyPairGenerator +1 More Practice Tags : JavaMisc Similar Reads KeyPairGenerator getInstance() method in Java with Examples getInstance(String algorithm) The getInstance() method of java.security.KeyPairGenerator class is used to return a KeyPairGenerator object that generates public/private key pairs for the specified algorithm.
