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.
