Trail: Security in Java 2 SDK 1.2
Lesson: Generating and Verifying Signatures

Prepare Initial Program Structure

Here's the basic structure of the GenSig program. Place it in a file called GenSig.java.

import java.io.*;
import java.security.*;

class GenSig {

    public static void main(String[] args) {

        /* Generate a DSA signature */

        if (args.length != 1) {
            System.out.println("Usage: GenSig nameOfFileToSign");
            }
        else try {

        // the rest of the code goes here

        } catch (Exception e) {
            System.err.println("Caught exception " + e.toString());
        }
    }

}
