Generating and Verifying Signatures

Input the Signature Bytes

Next, input the signature bytes from the file specified as the second command line argument:

        FileInputStream sigfis = new FileInputStream(args[1]);
        byte[] sigToVerify = new byte[sigfis.available()]; 
        sigfis.read(sigToVerify);
        sigfis.close();

Now the byte array sigToVerify contains the signature bytes.
