I use Apache’s HttpClient library for all my URL related needs. It is a marvelous library that does most of the job behind the scenes. Compared the Java’s URL class, it is not as easy to use as Apache’s HttpClient. While using this library, a site that I commonly check for updates threw the exception message javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated.
When I checked the site, it seemed that its SSL certificated had expired. The only workaround for this is to create your own TrustManager. This class actually checks if the SSL certificate is valid. The scheme used by SSL is called X.509 and Java has a specific TrustManager for this scheme, called X509TrustManager.
This handy method created by theskeleton is just the perfect solution to have your HttpClient object bypass any SSL related errors and ensures that it accepts all SSL certificates of a site, whether it is expired or not.
public static HttpClient wrapClient(HttpClient base) {
try {
SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException { }
public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException { }
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx);
ssf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager ccm = base.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", ssf, 443));
return new DefaultHttpClient(ccm, base.getParams());
} catch (Exception ex) {
return null;
}
}
Another way is to recreate the keystore, for the keystore you should have the site in the CN=XXX.
the command as below:
1. Create keystore
keytool -genkey -dname "cn=daXXX.XXX.com,o=,c=" -storepass MB7BROKERpzn -keystore pznKeyStore.jks -alias pznsigned
2. Export the cert
keytool -export -keystore pznKeyStore.jks -alias pznsigned -file pznsslcert.cer
3. Create trust store for client
keytool -genkey -dname "cn=da957203.fmr.com,o=,c=" -storepass MB7BROKERpzn -keystore pznTrustStore.jks -alias pzntrustsigned
4. import the server cert
keytool -import -alias pzntrust -file pznsslcert.cer -keystore pznTrustStore.jks -storepass MB7BROKERpzn
5. use http client to call the server
try {
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
FileInputStream instream = new FileInputStream(new File(trustfname));
try {
trustStore.load(instream, passphrase.toCharArray());
} finally {
try { instream.close(); } catch (Exception ignore) {}
}
SSLSocketFactory socketFactory = new SSLSocketFactory(trustStore);
Scheme sch = new Scheme("https", 443, socketFactory);
httpclient.getConnectionManager().getSchemeRegistry().register(sch);
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
