//签名,使用CA证书的私钥进行签名，签名使用的算法为MD5WithRSA
newcert.sign(privateKey, "MD5WithRSA"); //这样便得到了经过CA签名后的证书
//把新证书存入证书库
//把新生成的证书存入一个新的证书库，也可以存入原证书库，
//存入新证书库，则新证书库中不仅包含原证书库中的所有条目，
//而且新增加了一个这次产生的条目。注意，这时，新产生的签名后的证书只
//包括公钥和主体信息及签名信息，不包括私钥信息。这里给出两种方式。
///////////////////////////////////////////////////////////////////////////
//方式一：存入新密钥库
///////////////////////////////////////////////////////////////////////////
/*
ks.setCertificateEntry(afteraliasName,newcert);
FileOutputStream out = new FileOutputStream(newLib);
//存入新库signedLib，并设置新库的库访问密码
ks.store(out,newLibPass);
out.close();
*/
///////////////////////////////////////////////////////////////////////////
//end 方式一
///////////////////////////////////////////////////////////////////////////
//也可以采用另外一种方式，存入原证书库中
//存入原库中，即在原证书库中增加一条证书，这个证书是原证书经过签名后的证书
//这个新证书含有私钥和私钥密码
///////////////////////////////////////////////////////////////////////////
//方式二，存入原密钥库
///////////////////////////////////////////////////////////////////////////
//先在原库中读出被签证书的私钥
PrivateKey prk = (PrivateKey) ks.getKey(aliasName, namePass);
java.security.cert.Certificate[] cchain = {newcert};
//存入原来的库,第二个参数为原证书的私钥，第三个参数为新证书的私钥密码，第三个参数为新证书
ks.setKeyEntry(afteraliasName, prk, afterNewPass, cchain); //用新密钥替代原来的没有签名的证书的密码
FileOutputStream out2 = new FileOutputStream(name);
ks.store(out2, storepass); //存入原来的库中，第二个参数为该库的访问密码
