Returns the public key of the subject (target) of the certification path, including any inherited public key parameters if applicable.

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);//from   w  ww.  ja v  a2s .c  o m

    CertPath cp = cf.generateCertPath(mylist);

    FileInputStream kin = new FileInputStream(args[0]);
    KeyStore ks = KeyStore.getInstance("JKS");
    ks.load(kin, args[1].toCharArray());

    PKIXParameters params = new PKIXParameters(ks);
    params.setRevocationEnabled(false);

    CertPathValidator cpv = CertPathValidator.getInstance("PKIX");

    PKIXCertPathValidatorResult result = (PKIXCertPathValidatorResult) cpv.validate(cp, params);

    PublicKey pbk = result.getPublicKey();
    byte[] pkenc = pbk.getEncoded();
    BigInteger pk = new BigInteger(pkenc);
    System.out.println(pk.toString(16));

    TrustAnchor anc = result.getTrustAnchor();
    X509Certificate xc = anc.getTrustedCert();
    System.out.println(xc.getSubjectDN());
    System.out.println(xc.getIssuerDN());
