Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    FileInputStream is = new FileInputStream("your.keystore");

    KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());
    keystore.load(is, "my-keystore-password".toCharArray());

    Enumeration e = keystore.aliases();
    for (; e.hasMoreElements();) {
        String alias = (String) e.nextElement();

        java.security.cert.Certificate cert = keystore.getCertificate(alias);
        if (cert instanceof X509Certificate) {
            X509Certificate x509cert = (X509Certificate) cert;

            // Get subject
            Principal principal = x509cert.getSubjectDN();
