public static void main(String[] args) {
    // Load the JDK's cacerts keystore file
    String filename = System.getProperty("java.home") + "/lib/security/cacerts".replace('/', File.separatorChar);
    FileInputStream is = new FileInputStream(filename);
    KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());
    char[] password = "changeit".toCharArray();
    //keystore.load(is, password.toCharArray());
    keystore.load(is, password);

    // This class retrieves the most-trusted CAs from the keystore
    PKIXParameters params = new PKIXParameters(keystore);
    // Get the set of trust anchors, which contain the most-trusted CA certificates
    java.security.cert.Certificate sapcert = keystore.getCertificate("SAPNetCA");
    PublicKey sapcertKey =  sapcert.getPublicKey();
    System.out.println(sapcertKey);
    Enumeration aliases = keystore.aliases();
    while (aliases.hasMoreElements()) {
       String alias = aliases.nextElement();
        //System.out.println("alias certificates :"+alias);
       if (keystore.isKeyEntry(alias)) {
            keystore.getKey(alias, password);
        }
    }
