Usage

From source file:MainClass.java

public static void main(String args[]) throws Exception {

    CertificateFactory cf = CertificateFactory.getInstance("X.509");
    List mylist = new ArrayList();
    FileInputStream in = new FileInputStream(args[0]);
    Certificate c = cf.generateCertificate(in);
    mylist.add(c);// ww  w .j a v a  2s . c om

    CertStoreParameters cparam = new CollectionCertStoreParameters(mylist);
    CertStore cs = CertStore.getInstance("Collection", cparam);
    X509CertSelector selec = new X509CertSelector();
    selec.setIssuer("CN=YourName,OU=Network Center," + "O=University,L=ZB,ST=Toronto,C=CN");
    Set clct = (Set) cs.getCertificates(selec);
    Object o[] = clct.toArray();
    for (int i = 0; i < o.length; i++) {
        X509Certificate ct = (X509Certificate) o[i];
        System.out.println("Certificate " + i + " ");
        System.out.println(ct.getSubjectDN());
