Run the following code to obtain the client certificate. Note: it is valid only for two-way authentication.

<% X509Certificate[] certs = (X509Certificate[]) request.getAttribute("javax.servlet.request.X509Certificate");if(null!=certs){for(X509Certificate c: certs){PublicKey publicKey = c.getPublicKey();out.println(publicKey.getFormat());out.println("<br/>");//out.println(c.getExtendedKeyUsage());X500Principal flag = c.getSubjectX500Principal();String[] ss = flag.getName().split(",");////CN=WCY_309184,OU=03for(String s:ss){// String[] ss1 = s.split(",", 1);out.println("<br/>");out.println(s);}}}else{out.println("X509Certificate is null.");}%>
