Prebuilt Binaries

Windows binaries for M2Crypto SSL Python library, courtesy of the grr project.

They're reproduced here, to improve availability.

• Python 2.7 64-Bit
• Python 2.7 32-Bit

These archives need to be installed by hand. They are not installable using the standard Python Setuptools support. I have taken the liberty of doing this, and making the installable packages available via PyPI by the names given:

• M2CryptoWin32
• M2CryptoWin64

Building M2Crypto From Source

In the event that you want or need to build M2Crypto from source, the directions below were those that appeared at the grr page above at the time of this writing, for your reference. They have been updated for Markdown.

Instructions from the grr Project

Components

ActiveState Perl

Download and install ActiveState Perl from: ActiveState Perl

E.g. ActivePerl-5.16.1.1601-MSWin32-x86-296175.msi

NASM

Download and install NASM from: NASM

E.g. nasm-2.10.06-installer.exe

Swig

Download and install swig from: swig

E.g. swigwin-2.0.9.zip

Extract in C:\grr-build

OpenSSL

Grab a copy of the latest version of OpenSSL from: OpenSSL and extract it in the build directory.

E.g. openssl-1.0.1e.tar.gz

For more info see: openssl-1.0.1e\INSTALL.W32 or openssl-1.0.1e\INSTALL.W64

To create a 32-bit build run the following commands from the Visual Studio command prompt:

set PATH=%PATH%;C:\Program Files\nasm
cd C:\grr-build\openssl-1.0.1e
perl Configure VC-WIN32 --prefix=C:\grr-build\openssl
ms\do_nsam.bat
nmake -f ms\ntdll.mak
nmake -f ms\ntdll.mak install

To create a 64-bit build run the following commands from the Visual Studio command prompt:

set PATH=%PATH%;C:\Program Files\nasm
cd C:\grr-build\openssl-1.0.1e
perl Configure VC-WIN64A --prefix=C:\grr-build\openssl
ms\do_win64a.bat
nmake -f ms\ntdll.mak
nmake -f ms\ntdll.mak install

Note that a \ at the end of the prefix path --prefix=C:\grr-build\openssl can cause nmake -f ms\ntdll.mak install to fail.

This will install openssl in C:\grr-build\openssl

Copy C:\grr-build\openssl\bin\libeay32.dll and C:\grr-build\openssl\bin\ssleay32.dll to C:\Python27\lib\site-packages\.

M2Crypto

Download the M2Crypto source from: M2Crypto

E.g. M2Crypto-0.21.1.tar.gz

Download the patch from: http://code.google.com/p/grr/downloads/detail?name=m2crypto-fixes.patch

To apply the patch run the following commands:

cd C:\grr-build\M2Crypto-0.21.1
patch -u -p0 < m2crypto-fixes.patch

In setup.py:

• replace self.openssl = 'C:\pkg' by self.openssl = 'C:\grr-build\openssl'
• replace name = 'M2Crypto.__m2crypto' , by name = '__m2crypto'

Build:

set PATH=%PATH%;C:\grr-build\swigwin-2.0.9
C:\Python27\python.exe setup.py build
C:\Python27\python.exe setup.py install

To get M2Crypto to work for PyInstaller:

1. Rename C:\Python27\lib\site-packages\M2Crypto-0.21.1-py2.7-win32.egg to C:\Python27\lib\site-packages\M2Crypto-0.21.1-py2.7-win32.egg.zip
2. extract M2Crypto-0.21.1-py2.7-win32.egg.zip into C:\Python27\lib\site-packages\ without a M2Crypto-0.21.1-py2.7-win32.egg sub directory
3. remove M2Crypto-0.21.1-py2.7-win32.egg.zip

Testing

You may have issues with getting M2Crypto to run. Test by running:

C:\python27\python.exe -c "import M2Crypto"

I get the error:

ImportError: DLL load failed: The specified module could not be found.

The import cannot find: libeay32.dll and/or ssleay32.dll make sure they are in C:\Python27\lib\site-packages\
