CAS (client) program to obtain the security certificate

You can use the following procedure to obtain a security certificate:

import java.io.BufferedReader;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.InputStream;import java.io.InputStreamReader;import java.io.OutputStream;import java.security.KeyStore;import java.security.MessageDigest;import java.security.cert.CertificateException;import java.security.cert.X509Certificate;import javax.net.ssl.SSLContext;import javax.net.ssl.SSLException;import javax.net.ssl.SSLSocket;import javax.net.ssl.SSLSocketFactory;import javax.net.ssl.TrustManager;import javax.net.ssl.TrustManagerFactory;import javax.net.ssl.X509TrustManager;public class InstallCert {    public static void main(String[] args) throws Exception {        String host;        int port;        char[] passphrase;        if ((args.length == 1) || (args.length == 2)) {            String[] c = args[0].split(":");            host = c[0];            port = (c.length == 1) ? 443 : Integer.parseInt(c[1]);            String p = (args.length == 1) ? "changeit" : args[1];            passphrase = p.toCharArray();        } else {            System.out                    .println("Usage: java InstallCert 
Compile installcert. Java and execute: Java installcert hostname, for example: Java installcert test.report.com: 8443
Or, in eclipse, change the main method of the above program to add two lines.
String [] A = {"test.report.com: 8443 "};
ARGs =;
Run directly
The following information is displayed:

Note: because it is static loading, You need to restart your web server to make the certificate take effect.
