Generate self signed certificate from intermediate CA using java












0















I am able to generate self signed certificate as root ca with following code.
However, unable to generate it as intermediate ca. How to use signed certificate to generate client certificate in java?



public static String generateSelfSignedCertificate()

    {

        String cert = null;

        try{

                CertAndKeyGen keyGen=new CertAndKeyGen("RSA","SHA1WithRSA",null);

                keyGen.generate(1024);

                X500Name x500Name = new X500Name("CN=EXAMPLE.COM");



                //Generate self signed certificate

                X509Certificate chain=new X509Certificate[1];

                chain[0]=keyGen.getSelfCertificate(new X500Name("CN=ROOT"), (long)365*24*3600);



                System.out.println("Certificate : "+chain[0].toString());

                cert  = chain[0].toString();

            }catch(Exception ex){

                ex.printStackTrace();

            }



        return cert;

    }

          SQL update select statement

          Image
          0 I'm trying to update an entry in my database (postgresql). I'm having a problem with updating the query: INSERT INTO prices (price, product_id) SELECT product_price, commn_id FROM products_temp as prod WHERE NOT EXISTS (SELECT * FROM prices od WHERE prod.commn_id = od.product_id) OR prod.product_price != ( SELECT price FROM prices as p WHERE p.product_id = prod.commn_id order by p.end desc LIMIT 1 ) Query works fine when i delete: OR prod.product_price != ( SELECT price FROM prices as p WHERE p.product_id = prod.commn_id order by p.end desc LIMIT 1 ) So it seems to me that it's looping through this operation. My question is, how can I fix it? sql postgresql
