_ssl
|

Python wrapper for the secure sockets library.
|
||||
|
||||
Get the latest source code for OpenSSL from
|
||||
http://www.openssl.org
|
||||
|
||||
Unpack into the "dist" directory, retaining the folder name from
|
||||
the archive - for example, the latest stable OpenSSL will install as
|
||||
dist/openssl-0.9.6g
|
||||
|
||||
You can (theoretically) use any version of OpenSSL you like - the
|
||||
build process will automatically select the latest version.
|
||||
|
||||
You must also install ActivePerl from
|
||||
http://www.activestate.com/Products/ActivePerl/
|
||||
as this is used by the OpenSSL build process. Complain to them <wink>
|
||||
|
||||
The MSVC project simply invokes PCBuild/build_ssl.py to perform
|
||||
the build. This Python script locates and builds your OpenSSL
|
||||
installation, then invokes a simple makefile to build the final .pyd.
|
||||
|
||||
build_ssl.py attempts to catch the most common errors (such as not
|
||||
being able to find OpenSSL sources, or not being able to find a Perl
|
||||
that works with OpenSSL) and give a reasonable error message.
|
||||
If you have a problem that doesn't seem to be handled correctly
|
||||
(eg, you know you have ActivePerl but we can't find it), please take
|
||||
a peek at build_ssl.py and suggest patches. Note that build_ssl.py
|
||||
should be able to be run directly from the command-line.
|
||||
|
||||
build_ssl.py/MSVC isn't clever enough to clean OpenSSL - you must do this
|
||||
by hand.
