Document

Creates a FileInputStream by using the file descriptor fdObj, which represents an existing connection to an actual file in the file system.

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.j av 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");
