"""Pyme: GPGME Interface for Python
|
|
|
|
Welcome to PyME, the GPGME Interface for Python. "Pyme", when prounced,
|
|
rhymes with "Pine".
|
|
|
|
The latest release of this package may be obtained from
|
|
https://www.gnupg.org
|
|
|
|
Previous releases of this package for Python 2 can be obtained from
|
|
http://pyme.sourceforge.net
|
|
|
|
FEATURES
|
|
--------
|
|
|
|
* Feature-rich, full implementation of the GPGME library. Supports
|
|
all GPGME features. Callback functions may be written in pure
|
|
Python. Exceptions raised in callbacks are properly propagated.
|
|
|
|
* Ability to sign, encrypt, decrypt, and verify data.
|
|
|
|
* Ability to list keys, export and import keys, and manage the keyring.
|
|
|
|
* Fully object-oriented with convenient classes and modules.
|
|
|
|
QUICK EXAMPLE
|
|
-------------
|
|
|
|
>>> import pyme
|
|
>>> with pyme.Context() as c:
|
|
>>> with pyme.Context() as c:
|
|
... cipher, _, _ = c.encrypt("Hello world :)".encode(),
|
|
... passphrase="abc")
|
|
... c.decrypt(cipher, passphrase="abc")
|
|
...
|
|
(b'Hello world :)',
|
|
<pyme.results.DecryptResult object at 0x7f5ab8121080>,
|
|
<pyme.results.VerifyResult object at 0x7f5ab81219b0>)
|
|
|
|
GENERAL OVERVIEW
|
|
----------------
|
|
|
|
For those of you familiar with GPGME, you will be right at home here.
|
|
|
|
Pyme is, for the most part, a direct interface to the C GPGME
|
|
library. However, it is re-packaged in a more Pythonic way --
|
|
object-oriented with classes and modules. Take a look at the classes
|
|
defined here -- they correspond directly to certain object types in GPGME
|
|
for C. For instance, the following C code:
|
|
|
|
gpgme_ctx_t context;
|
|
gpgme_new(&context);
|
|
...
|
|
gpgme_op_encrypt(context, recp, 1, plain, cipher);
|
|
|
|
Translates into the following Python code:
|
|
|
|
context = core.Context()
|
|
...
|
|
context.op_encrypt(recp, 1, plain, cipher)
|
|
|
|
The Python module automatically does error-checking and raises Python
|
|
exception pyme.errors.GPGMEError when GPGME signals an error. getcode()
|
|
and getsource() of this exception return code and source of the error.
|
|
|
|
IMPORTANT NOTE
|
|
--------------
|
|
This documentation only covers a small subset of available GPGME functions and
|
|
methods. Please consult the documentation for the C library
|
|
for comprehensive coverage.
|
|
|
|
This library uses Python's reflection to automatically detect the methods
|
|
that are available for each class, and as such, most of those methods
|
|
do not appear explicitly anywhere. You can use dir() python built-in command
|
|
on an object to see what methods and fields it has but their meaning can
|
|
be found only in GPGME documentation.
