Installing pycrypto on Windows #34

This is just to help people with problems installing oauthlib on Windows due to pycrypto dependency.

oauth library depends on pycrypto library which is not pure Python library (has some c extensions). For this reason pycrypto can't be installed from source on Windows without Visual Studio 2008 installed (needed to compile these c extensions of pycrypto). The simplest solution is to download binary installers and install them using easy_install (pip doesn't support installing of binaries). 32bit binary installers for Python 2.2-2.7 and 64bit binary installer for Python 2.6 are at The Voidspace Python Modules and 64bit binary installer for Python 2.7 is at Compiling pycrypto on Win7-64. Binary installers can be installed in virtualenv - see


I'd enjoy us switching to the rsa module if possible.

Better yet, it would better if oauthlib had a soft dependency on pycrypto,


Closing since it's in the docs.
