Hi all ,

I have this piece of code below using JDK 1.3 and BouncyCastle Provider



//some other import ... i am using bouncyCastle Provider

import javax.crypto.Cipher;

import org.bouncycastle.jce.PKCS10CertificationRequest;

import org.bouncycastle.asn1.x509.X509Name;



public class test

{

public static void main(String []args) throws Exception

{

Security.addProvider(new
org.bouncycastle.jce.provider.BouncyCastleProvider());





KeyStore ks=KeyStore.getInstance("JKS");


ks.load(new FileInputStream
("test.keystore"),"one1234".toCharArray());





Enumeration e = ks.aliases();

X509Certificate c=null;



while(e.hasMoreElements())

{

String alias = e.nextElement().toString();

if(ks.isKeyEntry(alias))

{

c = (X509Certificate) ks.getCertificate(alias);

break;

}

}



String subject = c.getSubjectDN().getName();

X509Name xname = new X509Name(subject);



PrivateKey priv = (PrivateKey) ks.getKey
("mykey","one1234".toCharArray());

PublicKey pub = (PublicKey) c.getPublicKey();



PKCS10CertificationRequest csr = new
PKCS10CertificationRequest("MD5WithRSA",xname,
pub,null,priv);



byte buf[] = csr.getEncoded();



FileOutputStream os = new FileOutputStream
("request.crt");
OutputStreamWriter wr = new OutputStreamWriter(os);

wr.write("-----BEGIN NEW CERTIFICATE REQUEST-----
");

wr.write(new sun.misc.BASE64Encoder().encode(buf));

wr.write("
-----END NEW CERTIFICATE REQUEST-----
");

wr.flush();

}



}









The coding Was OKAY and ran successfully...



The Problem is i want to get the same result as if i
generate a csr using KEYTOOL utility...

BUT somehow i got different result , is it due because
of signature algorithm or encoding ??




Please help me ....

Thanks....
