sorry im using Bouncy Castle for encryption
This is my code
try {

               Enumeration e = ks.aliases();
               String keyAlias = null;
               String alias = null;
               while (e.hasMoreElements()) {
                    alias = (String) e.nextElement();
                    if (ks.isKeyEntry(alias)) {
                         keyAlias = alias;
               Certificate[] chain = ks.getCertificateChain(keyAlias);
               // create the generator for creating an smime/encrypted message
               SMIMEEnvelopedGenerator gen = new SMIMEEnvelopedGenerator();
