KeyStore isCertificateEntry() method in Java, examples Original text: https://www . geesforgeks . org/keystore-iscertifientry-method-in-Java-with-examples/ The isCertificateEntry() method of the java.security.KeyStore class is used to check whether the specified certificate entry exists in this KeyStore instance. It returns a boolean value representing the same. Syntax: public final boolean isCertificateEntry(String alias) throws KeyStoreException Parameters:This method accepts alias The name of the parameter whose certificate entry is to be checked. Return Value: This method checks whether the certificate entry for the requested alias exists and returns a Boolean value. Exception: If the keystore has not been initialized, this method throws KeystoreException. Note: None of the programs in this article will run on the online IDE because the “privatekey” keystore does not exist. You can inspect this code on your system’s Java compiler. To check this code, create a keystore “privatekey” on your system and set your own keystore password to access the keystore. The following is an example illustrating the iscertificientry() method: Example 1: // Java program to demonstrate getCertificate() methodimport java.security.*;import java.security.cert.*;import java. util.*;import java.io.*;public class GFG { public static void main(String[] argv) { try { creating the object of KeyStore span> KeyStore sr = KeyStore.getInstance(“JKS”); // keystore password is required to access keystore char[] pass = (“123456”).toCharArray(); //…
