hi!

i am wondering if anyone has used pyopenssl on a pocket pc. I have built
openSSL for pocket pc (a few dll's) and it passed all the tests.
To build pyopenssl, do i need openssl source or can i just use the dll's.
thanks

cheers

Well, you need the OpenSSL header files, of course, but other than
that, just the dlls.

If you need to hack setup.py to get it to compile, please send me a
patch and include the values of sys.platform and os.name so I know
what to test for.

Subject: [pyOpenSSL] building for winCE
Message-ID: <1096294972.4158223cbe2f2@www-mail.usyd.edu.au>

hi!

i built PyOpenSSL for WinCE, but when i was getting an error on import.
thinking that perhaps the way i went about doing it wasn't correct (i
didn't use setup.py since i dont have enough knowhow about hacking it to
make it work on WinCE, i simply combined all the C code and compiled it
into a DLL).

I then tried writing a simple C file that makes a few calls to the OpenSSL
API. the code is below.

this builds fine, but again when i do
>>>import testssl
i get
ImportError: DLL load failed. The specified module could not be found.

i am hoping people on this list, hopefully the developers of PyOpenSSL (who
have written code like the one below), could shed some light on what it is
thats wrong with my piece of code.

thanks

Well, if you get this kind of import error I highly doubt that you've
got a fully working build. When you build pyopenssl (python setup.py
build) you should end up with the following files in
build/lib.something/OpenSSL: __init__.py, version.py, tsafe.py,
rand.so, crypto.so, SSL.so.

"import OpenSSL" or "from OpenSSL import crypto, SSL" or what have you
*is* the right way to import the modules. If that doesn't work,
something's wrong.

i thought you could only import Python .py or .pyd files.
i am quite sure my build went okay. those are the files that i have. the
system admin on my server has already built PyOpenSSL. i tried import then
but that threw the same error.
So i built again to my home directory, added that to the path and tried
import from there. that gave the same error.
buiild and install didn't throw any errors or warnings at all.
i am running this on a solaris.

import now works. it was a faulty build.
but now from OpenSSL import SSL doesn't work. it throws the error

>>> from OpenSSL import SSL
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: ld.so.1: python: fatal: relocation error: file OpenSSL/SSL.so:
symbol SSL_renegotiate_pending: referenced symbol not found

while

>>> import OpenSSL
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/hons2004/abrar1/lib/python/OpenSSL/__init__.py", line 11, in ?
    import rand, crypto, SSL, tsafe
ImportError: ld.so.1: python: fatal: relocation error: file
OpenSSL/crypto.so: symbol OPENSSL_add_all_algorithms_noconf: referenced
symbol not found


any ideas what may be wrong here?

thanks

Subject: [pyOpenSSL] building and an error
Message-ID: <1096450507.415a81cb3ceb9@www-mail.usyd.edu.au>

hi!

i have built PyOpenSSL for WinCE using eVC++, trouble is import doesn't
work.
what i have done is, instead of hacking around distutils, i have simply
added all source and header files to a evc project and built them
(building all crypto to crypto.pyd and so on). the trouble is import
crypto throws an error saying initcrypto not defined.
i have checked the source and initcrypto is defined...i build PyOpenSSL in
the same way on a PC using VC++ 6.0 and that works okay so i dont know
where the error is coming from.

i am using the client.py and server.py in 'examples/simple' (i found the
examples :)) and would like no authentication at all. just an encrypted
exchange.
But when do
ctx.set_verify(VERIFY_NONE, verify_cb)
on both the client and server end, the server does not call verify_cb (as
expected) but the client makes the call and whats more it calls twice ( i
have a print statement in there).
how can i have no server authentication and where is the extra call
(shouldn't it be called only once)

thanks

cheers

hi!

i cant do a handshake using OpenSSL on a pocket pc. it throws up an error
saying PRNG not seeded(and it doesnt seed from the .rnd file since there
is no concept of a C:\ on the pocket pc and no environment variables
either)
If i get PyOpenSSL working on the PDA would it be possible for me to use
the rand interface to seed the PRNG and the use that to do the SSL
handshake.

Will that work?

i'm really short on time and so dont want to try something that may not
work.

thanks
