Ok, trying that...works, but the window doesn't stay open, so we can't see the results. Any way to do that? Sorry for the Windows-101 tutorial.

python openssl x509 CA
by Marcin Jurczuk Oct. 31, 2008

Oct. 31, 2008

Hello, I'm fighting with Certificate Authority functionality with python I stuck on following problem: How to sign CSR using CA key and write resulted certificate. You can do it using following openssl cmd: openssl ca -cert CA/cert.pem -keyfile CA/private/cakey.pem -policy policy_anything -out user_cert.pem -infiles userreq.pem My try was: import OpenSSL.crypto as pki #load CA key: ca_key=pki.load_privatekey(pki.FILETYPE_PEM,open('CA/private/ cakey.pem').read(),'haselko') #load user's csr: csr=pki.load_certificate_request(pki.FILETYPE_PEM,open('userreq.pem').read()) # sign csr csr.sign(ca_key,'sha1') I don't get any erorrs however I dont' see any way to write or get result from such operation csr exports following methods: csr.add_extensions csr.get_pubkey csr.get_subject csr.set_pubkey csr.sign csr.verify I want to create pure python implementation without use of openssl wrapped with python code. Regards,

Can you elaborate on this? I have some very simple command-line utilities I would like to make available on different platforms, but what little I knew about Windows is fading into the past. This example: import sys print sys.stdin.read() ...works in the Windows XP dos box if I do: python demo.py < file.txt ...but I get the error 9 for: demo.py < file.txt Is there any way to make the second version work on Windows? -Bill -- Sattre Press The King in Yellow http://sattre-press.com/ by Robert W.

Exec and Scope
by Emanuele D'Arrigo Oct. 31, 2008

Oct. 31, 2008

Hi everybody! I'm trying to do something in a way that is probably not particularly wise but at this point I don't know any better, so bear with me. Suppose in main.py I have the following statements: myObject = MyObject() execThis("myObject.myCommand()") Now suppose the method def execThis(aCommandInAString): exec(aCommandInAString) is somewhere "far away" in terms of scope. Somewhere where the code doesn't know anything about the instance myObject and even less about its methods and attributes. How do I get myObject.myCommand() properly executed? I'm guessing it's about taking a snapshot of or a reference to the namespace that is correct for the execution of the command, but... is that the case? And how do I get a handle to that? Thanks for your help! Manu

I suppose they could install cygwin and run bash, but that seems like overkill for what should be a simple task. -Bill -- Sattre Press The King in Yellow http://sattre-press.com/ by Robert W.

Selecting multiple directories (TKinter)
by Fabian Svara Oct. 31, 2008

Oct. 31, 2008

Hi, I'm currently using tkFileDialog.askdirectory() to select a single directory. I would like to be able to select multiple directories. tkFileDialog.askopenfilenames() seems to do this for files. What can I do in my situation? Are there alternative classes that provide file dialogs better suited for my purpose? Thanks! Fabian

Can I build Python with lthread instead of pthread?
by Akira Kitada Oct. 31, 2008

Oct. 31, 2008

Hi, I'm running Python 2.5 on FreeBSD 4. pthread on FreeBSD 4 has some problems so I would like to build python with lthread (linuxthreads) instead of BSD's pthread. So I looked at configure options but couldn't find any options for it. Python support lthread? and how can I build python with it? Thanks in advance, Akira
