Today I needed to install PyCrypto into a virtualenv on a Windows box
that didn't have a compiler. I found that using easy_install against
the installer executable worked well.
REM download a PyCrypto installer from
REM say, pycrypto-2.6.win32-py2.7.exe
More than two years later, there's still zero Windows-related
information on building or installing PyCrypto anywhere on the
website. Since it's non-trivial, this omission continues to disappoint

With all the export regulations, I can understand why you might not want to supply pre-built binaries, but it would be good to explain how to do it. Michael Foord has supplied such binaries for earlier versions of PyCrypto, but there's none available for PyCrypto 2.5 yet.
