The easiest way to do this is to build from source (which has already been updated for 1.0.1h if you use the externals scripts in Tools\buildbot), and you should just be able to drop _ssl.pyd and _hashlib.pyd on top of a normal install.>> Aside: I wonder if it's worth changing to dynamically linking to OpenSSL? It would make this kind of in-place upgrade easier when people need to do it. Any thoughts? (Does OpenSSL even support it?)Yes, no problem at all, but you'd still have to either do a new releaseevery time a new OpenSSL problem is found (don't think that's anoption for Python) or provide new compiled versionscompatible with the Python modules needing the OpenSSL libs orinstructions on how to build these.Note that the hash routines are rarely affected by these OpenSSLbugs. They usually only affect the SSL/TLS protocol parts.Alternatively, you could make use of our pyOpenSSL distribution,which includes pyOpenSSL and the OpenSSL libs (also for Windows):http://www.egenix.com/products/python/pyOpenSSL/We created this to address the problem of having to updateOpenSSL rather often. It doesn't support Python 3 yet, buton the plus side, you do get OpenSSL libs which are compiledwith the same compiler versions used for the Python.orginstallers.-- Marc-Andre LemburgeGenix.comProfessional Python Services directly from the Source>>> Python/Zope Consulting and Support ...http://www.egenix.com/>>> mxODBC.Zope.Database.Adapter ...http://zope.egenix.com/>>> mxODBC, mxDateTime, mxTextTools ...http://python.egenix.com/________________________________________________________________________::: Try our new mxODBC.Connect Python Database Interface for free ! :::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
