NAME

EAFDSS - Electronic Fiscal Signature Devices Library

SYNOPSIS

  use EAFDSS; 

  $dh = new EAFDSS(
  	"DRIVER" => "$driver::$params",
	"SN"     => $serial,
	"DIR"    => $sDir,
	"DEBUG"  => $verbal
     );


  $result = $dh->Status();
  $result = $dh->Sign($fname);
  $result = $dh->Info();
  $result = $dh->SetTime($time);
  $result = $dh->GetTime();
  $result = $dh->SetHeaders($headers);
  $result = $dh->GetHeaders();

DESCRIPTION

The EAFDSS module handles the communication with an Electronic Signature Device (EAFDSS). It defines a set of methods common to all EAFDSS devices in order to communicate with the device but also handle all necessary file housekeeping requirements by Law, like creating A, B, C files.

ARCHITECTURE

This module is loosely (and shamelessly I may add) influenced by the architecture of the DBI module. There is a layer of a basic API that is common to all EAFDSS device drivers. Usually a developer of an EAFDSS application will only need to deal with functions only at that level. You have to be in need of something really special to access functions that are specific to a certain driver.

Methods

** INCOMPLETE **

EAFDSS->new("DRIVER" => "$driver::$params", "SN" => $serial, "DIR" => $sDir, "DEBUG" => $verbal);

Returns a newly created $driver object. The DRIVER argument is a compination of a driver and it's parameters. For instance it could be one of the following:

EAFDSS::SDNP::127.0.0.1

or

EAFDSS::Dummy:/tmp/dummy.eafdss

The SN argument is the Serial number of device we wan't to connect. Each device has it's own unique serial number. If the device's SN does not much with the provided then you will get an error.

The DIR argument is the directory were the signature files (A, B and C) will be created. Make sure the directory exist.

The last argument is the DEBUG. Use a true value in order to get additional information. This one is only useful to developers of the module itself.

$dh->Sign($filename)

That method will provide the contents of the file $filename to the EAFDSS and return it's signature.

$dh->Info

Get info about the device

$dh->SetTime

Set the time on the device

$dh->GetTime

Get the time of the device

$dh->SetHeaders

Set the headers

$dh->GetHeaders

Get the headers

VERSION

This is version 0.10. Which actually is the first release and an unstable release. Only for beta testers!
