A Python interface to FirmaSAT
==============================
This is a Python interface to the core FirmaSAT library, which must be
installed on your system. FirmaSAT is available from
https://www.cryptosys.net/firmasat/.
Classes
-------
**Sello**
Operates on the Sello (signature) node in a SAT XML document.
**Tfd**
Operates on the Timbre Fiscal Digital (TFD) element, if present.
**Pkix**
PKI X.509 security utilities. Operates on private keys and
X.509 certificates.
**Xmlu**
XML utilities. Operates on SAT-specific XML documents.
**Gen**
General info about the core library DLL, e.g. version
number, compile date.
**Err**
Details of errors returned by the core library DLL.
All code in is one module ``firmasat.py`` for simplicity of
distribution. All methods are static methods.
Errors
------
Most errors (missing files, invalid format) will result in a
``firmasat.Error`` exception, although some methods are more forgiving
and will return a negative error code instead. Passing a bad argument type
will result in an ``ArgumentError`` exception
Examples
--------
To use in Python's REPL:
::
>>> from firmasat import *
>>> Gen.version()
105028
If you don't like ``import *`` and find ``firmasat`` a bit long to type
each time, try
::
>>> import firmasat as fs
>>> fs.Gen.version()
105028
To sign a CFDI document, create the base XML file with all the required
data except the following nodes
::
Sello=""
Certificado=""
NoCertificado="30001000000300023708"
You must add the 20-digit serial number of your signing certificate to the
``NoCertificado`` node. See below.
Then run the ``Sello.sign_xml()`` method with full paths to your ``key``
and ``cer`` files.
::
n = Sello.sign_xml('new.xml', 'base.xml', "emisor.key", password, "emisor.cer")
This creates a new file ``new.xml`` with the Sello and Certificado nodes
completed.
Finding a certificate's serial number
-------------------------------------
::
>>> firmasat.Pkix.query_cert('emisor.cer', 'serialNumber')
'30001000000300023708'
or using FirmaSAT from the command line
::
> firmasat NUMBERCERT emisor.cer
30001000000300023708
Tests
-----
There is a series of tests in ``test_firmasat.py``. This requires a
subdirectory ``work`` in the same folder as the ``test_firmasat.py``
module containing all the required test files.
The test function then creates a temporary
subdirectory which is deleted automatically (add the argument
``nodelete`` on the command line to keep this temp directory).
::
test/
test_firmasat.py # this module
work/ # this _must_ exist
<all required test files>
tmp.XXXXXXXX/ # created by `setup_temp_dir()`
<copy of all required test files>
<files created by tests>
This structure is already set up in the distribution file, so unzip the
file ``firmasat-x.x.x.zip`` and open a command-line prompt in the
``test`` subdirectory. You can do any of the following.
1. ``python test_firmasat.py``
2. ``py.test -v``
3. Open the file ``test_firmasat.py`` using IDLE and select
``Run > Run Module (F5)``.
We've tested this using the Python 3.10.8 interpreter and IDLE, the
PyDev environment in Eclipse, and using ``py.test``.
System requirements
-------------------
Windows platforms only. Python 3 must be installed on your system (at
least 3.6). FirmaSAT v10.50 or above must also be installed.
