very thanks, pk.get_rsa().pub() can get a tuple with E and N, I tried
this function, in ubuntu 8.10, the program crashed, In windows, it
works, maybe there's a bug in ubuntu version, but no matter, my
program will just on windows.

                        Version 0.8.1-0.9.8j-1


             An easy to install and use repackaged distribution
               of the pyOpenSSL Python interface for OpenSSL -
                  available on Windows and Unix platforms

INTRODUCTION

The eGenix.com pyOpenSSL Distribution includes everything you need to
get started with SSL in Python. It comes with an easy to use installer
that includes the most recent OpenSSL library versions in pre-compiled
form.

pyOpenSSL is an open-source Python add-on (http://pyopenssl.sf.net/)
that allows writing SSL aware networking applications as well as
certificate management tools.

OpenSSL is an open-source implementation of the SSL protocol
(http://www.openssl.org/).

For more information, please see the product page:

________________________________________________________________________

NEWS

This new release of the eGenix.com pyOpenSSL Distribution fixes a
serious problem in pyOpenSSL 0.8 related to threaded applications.

The problem causes invalid thread states in the Python interpreter which
then result in random core dumps and seg faults. The patch was provided
by Maxim Sobolev on SourceForge:

http://sourceforge.net/tracker/index.php?func=detail&aid=2543118&group_id=31249&atid=401760

Note that this patch has not yet been integrated into upstream
pyOpenSSL.

We have also fixed several compiler warnings found in the code. The
version of pyOpenSSL you find in the source release has those patches
applied.

Binaries are available for Linux x86 and x64 as well as Windows x86
and include pyOpenSSL as well as the OpenSSL libraries.

For Plone users and friends of buildout scripts, we have added
pre-built binaries for Windows. They install just like the Linux
versions and allow easy integration of the archives into buildout
scripts.

UPGRADING

Before installing this version of pyOpenSSL, please make sure that
you uninstall any previously installed pyOpenSSL version. Otherwise,
you could end up not using the included OpenSSL libs.

Subject: [PYTHON-CRYPTO] Add ANS1_UTCTIME.get_datetime function
Message-ID: <20090324125442.GA6465@grid.pp.ru>

OpenSSL ASN1_UTCTIME_print (and other time printing functions) produce
output not suitable for parsing with strptime:
 * Month name are not locale-dependant so python strptime fail to
   recognize them (e.g. in gtk applications)
 * Timezone is either missing or ' GMT' (with space)

Proposed patch adds get_datetime function that returns python
datetime.datetime structure with correct timezone. If this function
looks suitable I'll add tests.
                Pavel

P.S. Error messages are not perfect so they must be changed.

Yes, I'd welcome such a change. With tests of course :)

For symmetry, could you also add set_datetime method?

Make a bugzilla bug and attach the patch there, so I can find it in my
review queue.

Thanks,
