Do never, never and never change libcrypto library files.
On Mac OS X if you move them out of the lib folder, overwrite with some other version or somehow else destroy them, you are lost.
Nearly no application will launch. Finder can't copy files any more as all the authorization stuff won't work.
Terminal will not be able to use sudo or su commands. VMWare will crash on startup.
Solution: Target disc mode and fix from other Mac.
so don't replace files in /usr/lib.
