 +At the bottom of this page, is the compiler used to make Python 2.6 and 2.7 [[http://www.microsoft.com/visualstudio/en-us/products/2010-editions/express#Visual_Studio_2008_Express_Downloads|Visual Studio 2008 Express]].
 +
 +On Windows, you'll have to make the following change:
 +<code>
 +$ diff bcrypt_python.c.org bcrypt_python.c
 +70a71,72
 +>       char *password_copy;
 +>       char *salt_copy;
 +76,77c78,79
 +<       char *password_copy = strdup(password);
 +<       char *salt_copy = strdup(salt);
 +---
 +>       password_copy = strdup(password);
 +>       salt_copy = strdup(salt);
 +</code>
 +
 +Then you can build it with setup, like so:
 +
 +<code>
 +c:\Python27\python.exe setup.py build
 +</code>

Note that pycrypto-2.3 can be built with the same ''c:\Python27\python.exe setup.py build'' mechanism.

 +Someone suggested [[wp>Whirlpool_(cryptography)]], it's offered in [[http://labix.org/python-mhash|mhash]], and a pure-python implementation from Bjorn Edstrom <be@bjrn.se> 16 december 2007 is here [[http://www.bjrn.se/code/whirlpoolpy.txt]].

 +==== Verification ==== 
 + 
 +Maybe I should try to automate a way to verify the SHA1 Checksums of PGP signatures and upon success, verify the PHP signatures.  Here's an old recipe: [[http://dannyman.toldme.com/2007/03/30/howto-verify-pgp-signature/|HOWTO: Verify a PGP Signature]].
