Hello all,

I have an web application that conect with https and request a client certification.
i get the client certificate from the request:

    X509Certificate[] certs = (X509Certificate[])request.getAttribute("javax.servlet.request.X509Certificate");
    X509Certificate cert = certs[0];
    String dn = cert.getSubjectDN().getName();

this string: "CÚsar Fernßndez"

i want the string that appears well in the Internet Explorer is: "César Fernández" (name with accents)

i intent:
    byte[] value = dn.getBytes();
    String dnS = new String(value, "ISO-8859-1");

but it don't works.

thanks in advance,
   César.

Hi,
Don't know if if works but try this:
X509Certificate[] certs = (X509Certificate[])request.getAttribute("javax.servlet.request.X509Certificate");
    X509Certificate cert = certs[0];
X500Principal principal = (X500Principal) cert.getSubjectDN();
String dn = principal.getName(X500Principal.CANONICAL);
 or
String dn = principal.getName(X500Principal.RFC1779);

Best regards, Mircea

Hello,

César.

I am not good in encryption but I got this example
from the sun security forum and this example works prity good.

import java.security.Security;
import java.security.Key;
import java.security.KeyPair;
import java.security.KeyFactory;
import java.security.KeyPairGenerator;
import java.security.SecureRandom;
import sun.misc.BASE64Encoder;
import java.security.spec.X509EncodedKeySpec;
import org.bouncycastle.util.encoders.Base64;
import java.io.*;
...
      //Restore Keys from the File
        KeyFactory kf = java.security.KeyFactory.getInstance("RSA","BC");
        BufferedReader br = new BufferedReader(new FileReader(fileName));
        StringBuffer keyBase64 = new StringBuffer();
        String line = br.readLine ();
        Key key = null;
        
        while(line != null)
        {
           keyBase64.append (line);
           line = br.readLine ();
        }
        
        byte [] bytes = new sun.misc.BASE64Decoder().decodeBuffer(keyBase64.toString ());
