Dear All,
i actually want to create my own private key and certificate which i would
use to sign an adobe eForm.but i am stucked here in even generating the
key.Any hint or guidance will be highly appreciated.
This code is giving the error as:
Exception in thread "main" java.security.NoSuchProviderException: no such
provider: SUN
at sun.security.jca.GetInstance.getService(GetInstance.java:82)

public class KeyGeneration {
public static void main(String args[]) throws
NoSuchAlgorithmException, NoSuchProviderException, IOException
{
KeyPairGenerator keyGen =
KeyPairGenerator.getInstance("RSA");//here the public/private key pair is
generated for the algorithm RSA
SecureRandom random = SecureRandom.getInstance("SHA1PRNG",
"SUN");//
keyGen.initialize(1024, random);
java.security.KeyPair keyPair = keyGen.generateKeyPair();
PrivateKey privKey = keyPair.getPrivate();
PublicKey pubKey = keyPair.getPublic();
FileOutputStream fos = new FileOutputStream(new
File("C:\\privatekey.key"));
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(privKey);
oos.close();
fos.close();
fos = new FileOutputStream(new File("C:\\lpublickey.key"));
oos = new ObjectOutputStream(fos);
oos.writeObject(pubKey);
oos.close();
fos.close();
}
}
