No (alas) that didn't work.

So after I'd copied ssleay32.a to c:\python26\lib, I then had it both there
and in c:\python26\libs (where you need it for the build).

c:\python26\lib is, of course, in my Windows PATH.

well dumpbin recognizes, say, ssl.pyd as a to-at-least-some-extent
well-formed DLL.

But even when I put the prebuilt ( the pyopenssl-win download )
module into place, the DLLs (not unsurprisingly) refused to import.

So how does this work and what's the problem?

Windows is still largely a mystery to me, so I can't tell you how it works.
I do think that I understand the problem, which is that the OpenSSL library
isn't being found by Windows.  The pyOpenSSL library ssl.pyd is linked
against it.  Since you said you already have the OpenSSL libraries in the
Python libs directory, I'm not sure why it's not being found.

Here's a dumpbin of ssl.pyd's dependencies:

well it lost all its formatting when it arrived here in the mailing list 
archive on
sourceforge

but I see that if one clicks on the 'Mail as HTML' part of Attachments, 
it will bring
up my message, properly formatted, in a browser window.

How does one actually respond here so as to maintain the same thread?

Re: [pyOpenSSL] DLL load failed.

[patrick f. <pa...@we...>]

Figured it out at least this far - it's the 64 bit-ness.

I installed the OpenSSL prebuilt module into a python 2.5 installation 
on a 32 bit windows machine.

mk_simple_certs.py ran successfully and produced the certs (in the 
simple subdirectory).

So I think it fair to say this all of this stuff will work on a 32-bit 
machine - but not a 64-bit machine.

I'm considering installing a 3.x version of python to see if this 
handles 64-bit windows better (in particular how python loads DLLs).

Note that on a 64-bit machine you have two versions of the system32 
directory (where Windows DLLs are often put):

c:\windows\system32

c:\windows\sysWOW64

Confusingly the first (which is the same as the old 32 bit name) is the 
64 bit location.  WOW64 is actually the 32 bit location.
