[PYTHON-CRYPTO] random number module

I'd like to submit a secure RNG module for Python 2.3. Like block
ciphers, Guido has also expressed interest in this.
I included a Linux implementation in the block cipher reference
implementation that I just sent the url for:
It works by reading pseudo-random bytes from /dev/urandom, i.e. it
lets the kernel do the heavy lifting. I've been using it for quite
a while and I'm pretty happy with the interface.
There needs to be something similar for Windows, that gets random
bytes by calling CryptGenRandom function in the Windows CAPI,
preferably using a CSP of the user's choice, but it's ok if it uses
the standard Microsoft CSP. All that's needed is a dll with one or
two entry points, to select the CSP and to read N random bytes with a
CAPI call. I'd write this, except I'm mostly a Linux user and I don't
have any Windows dev tools.
Are there any Windows programmers here willing to do this? I'll
provide whatever assistance I can, given that I can't compile or
easily test the code. But I can help interpret the CAPI documentation
if that's useful.
