If you want to configure Apache2 under Windows to use OpenSSL - please, for the love of God, do NOT copy around, or even worse - overwrite any DLL's.
First, modern Apache2 is shipped with relevant libraries, second - even if, for some reason, it can't find the right now - you can TELL it to use the right ones.
LoadLibrary.
Yes.
That simple.
LoadLibrary C:/apache2/bin/libeay32.dll
LoadLibrary C:/apache2/bin/ssleay32.dll
LoadLibrary C:/php5/php5ts.dll
LoadModule php5_module C:/php5/php5apache2_4.dll
