Contribution Guidelines
|
||||
=======================
|
||||
|
||||
Before opening proposing any pull requests (about code or documentation),
|
||||
please open an issue.
|
||||
|
||||
Code Contributions
|
||||
------------------
|
||||
|
||||
When contributing code, you'll want to follow this checklist:
|
||||
|
||||
1. Fork the repository on GitHub.
|
||||
2. Run the tests to confirm they all pass on your system. If they don't, you'll
|
||||
need to investigate why they fail.
|
||||
3. Write tests that demonstrate your bug or feature. Ensure that they fail.
|
||||
4. Make your change.
|
||||
5. Run the entire test suite again, confirming that all tests pass *including
|
||||
the ones you just added*.
|
||||
6. Send a GitHub Pull Request to the main repository's ``master`` branch.
|
||||
GitHub Pull Requests are the expected method of code collaboration on this
|
||||
project.
|
||||
|
||||
Code Style
|
||||
~~~~~~~~~~
|
||||
|
||||
Please try to respect the `PEP 8`_ code style.
|
||||
|
||||
|
||||
To get the greatest chance of helpful responses, please also observe the
|
||||
following additional notes.
|
||||
|
||||
.. _PEP 8: http://pep8.org
|
||||
|
||||
|
||||
Documentation Contributions
|
||||
---------------------------
|
||||
|
||||
Documentation improvements are always welcome! The documentation files live in
|
||||
the ``docs/`` directory of the codebase. They're written in
|
||||
`reStructuredText`_, and use `Sphinx`_ to generate the full suite of
|
||||
documentation.
|
||||
|
||||
When contributing documentation, please do your best to follow the style of the
|
||||
documentation files. This means a soft-limit of 79 characters wide in your text
|
||||
files and a semi-formal, yet friendly and approachable, prose style.
|
||||
|
||||
When presenting Python code, use single-quoted strings (``'hello'`` instead of
|
||||
``"hello"``).

||||

||||

Good Bug Reports
|
||||
----------------
|
||||
|
||||
Please be aware of the following things when filing bug reports:
|
||||
|
||||
1. Avoid raising duplicate issues. *Please* use the GitHub issue search feature
|
||||
to check whether your bug report or feature request has been mentioned in
|
||||
the past. Duplicate bug reports and feature requests are a huge maintenance
|
||||
burden on the limited resources of the project. If it is clear from your
|
||||
report that you would have struggled to find the original, that's ok, but
|
||||
if searching for a selection of words in your issue title would have found
|
||||
the duplicate then the issue will likely be closed extremely abruptly.
|
||||
2. When filing bug reports about exceptions or tracebacks, please include the
|
||||
*complete* traceback. Partial tracebacks, or just the exception text, are
|
||||
not helpful. Issues that do not contain complete tracebacks may be closed
|
||||
without warning.
|
||||
3. Make sure you provide a suitable amount of information to work with. This
|
||||
means you should provide:
|
||||
|
||||
- Guidance on **how to reproduce the issue**. Ideally, this should be a
|
||||
*small* code sample that can be run immediately by the maintainers.
|
||||
Failing that, let us know what you're doing, how often it happens, what
|
||||
environment you're using, etc. Be thorough: it prevents us needing to ask
|
||||
further questions.
|
||||
- Tell us **what you expected to happen**. When we run your example code,
|
||||
what are we expecting to happen? What does "success" look like for your
|
||||
code?
|
||||
- Tell us **what actually happens**. It's not helpful for you to say "it
|
||||
doesn't work" or "it fails". Tell us *how* it fails: do you get an
|
||||
exception? A hang? A non-200 status code? How was the actual result
|
||||
different from your expected result?
|
||||
- Tell us **what version of Stegano you're using**, and
|
||||
**how you installed it**. Different versions of Stegano behave
|
||||
differently and have different bugs.
|
||||
|
||||
If you do not provide all of these things, it will take us much longer to
|
||||
fix your problem. If we ask you to clarify these and you never respond, we
|
||||
will close your issue without fixing it.
|
||||
|
||||
|
||||
Questions
|
||||
=========
|
||||
|
||||
The GitHub issue tracker is for *bug reports* and *feature requests*. Please do
|
||||
not use it to ask questions about how to use Stegano. These questions should
|
||||
instead be directed to Stack Overflow. Make sure
|
||||
that your question is tagged with the `python-stegano` tag when asking it on
|
||||
Stack Overflow, to ensure that it is answered promptly and accurately.
|
||||
You can search for questions with
|
||||
`these tags <http://stackoverflow.com/questions/tagged/python+steganography>`_.

Stegano
|
||||
-------
|
||||
|
||||
[](https://builds.sr.ht/~cedric/Stegano?)
|
||||
|
||||
|
||||
[Stegano](https://github.com/cedricbonhomme/Stegano), a pure Python
|
||||
Steganography module.
|
||||
|
||||
Steganography is the art and science of writing hidden messages in such a way
|
||||
that no one, apart from the sender and intended recipient, suspects the
|
||||
existence of the message, a form of security through obscurity. Consequently,
|
||||
functions provided by Stegano only hide messages, without encryption.
|
||||
Steganography is often used with cryptography.
|
||||
|
||||
# Installation
|
||||
|
||||
|
||||
```bash
|
||||
$ pipenv install Stegano
|
||||
```
|
||||
|
||||
You will be able to use Stegano in your Python programs.
|
||||
|
||||
If you only want to install Stegano as a command line tool:
|
||||
|
||||
```bash
|
||||
$ pipx install Stegano
|
||||
```
|
||||
|
||||
pipx installs scripts (system wide available) provided by Python packages into
|
||||
separate virtualenvs to shield them from your system and each other.
|
||||
|
||||
|
||||
# Usage
|
||||
|
||||
A [tutorial](https://stegano.readthedocs.io) is available.
|
||||
|
||||
|
||||
## Use Stegano as a library in your Python program
|
||||
|
||||
If you want to use Stegano in your Python program you just have to import the
|
||||
appropriate steganography technique. For example:
|
||||
|
||||
```python
|
||||
>>> from stegano import lsb
|
||||
>>> secret = lsb.hide("./tests/sample-files/Lenna.png", "Hello World")
|
||||
>>> secret.save("./Lenna-secret.png")
|
||||
>>>
|
||||
>>> clear_message = lsb.reveal("./Lenna-secret.png")
|
||||
```
|
||||
|
||||
|
||||
## Use Stegano as a command line tool
|
||||
|
||||
### Hide and reveal a message
|
||||
|
||||
```bash
|
||||
$ stegano-lsb hide -i ./tests/sample-files/Lenna.png -m "Secret Message" -o Lena1.png
|
||||
$ stegano-lsb reveal -i Lena1.png
|
||||
Secret Message
|
||||
```
|
||||
|
||||
|
||||
### Hide the message with the Sieve of Eratosthenes
|
||||
|
||||
```bash
|
||||
$ stegano-lsb-set hide -i ./tests/sample-files/Lenna.png -m 'Secret Message' --generator eratosthenes -o Lena2.png
|
||||
```
|
||||
|
||||
The message will be scattered in the picture, following a set described by the
|
||||
Sieve of Eratosthenes. Other sets are available. You can also use your own
|
||||
generators.
|
||||
|
||||
This will make a steganalysis more complicated.
|
||||
|
||||
|
||||
## Running the tests
|
||||
|
||||
```bash
|
||||
$ python -m unittest discover -v
|
||||
```
|
||||
|
||||
Running the static type checker:
|
||||
|
||||
```bash
|
||||
$ python tools/run_mypy.py
|
||||
```
|
||||
|

`Stegano <https://github.com/cedricbonhomme/Stegano>`_, a pure Python
|
||||
Steganography module.
|
||||
|
||||
Steganography is the art and science of writing hidden messages in such a way
|
||||
that no one, apart from the sender and intended recipient, suspects the
|
||||
existence of the message, a form of security through obscurity. Consequently,
|
||||
functions provided by Stegano only hide messages, without encryption.
|
||||
Steganography is often used with cryptography.
|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
.. code:: bash
|
||||
|
||||
$ pipenv install Stegano
|
||||
✨🐍✨
|
||||
|
||||
You will be able to use Stegano in your Python programs.
|
||||
|
||||
If you only want to install Stegano as a command line tool:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
$ pipx install Stegano
|
||||
