Does crypt() work under Windows NT?

No.

This is because php shells out to the unix crypt command when it sees
crypt in a script, and NT doesn't have that command available.

There are some fairly simple encryption algorithms knocking about.
For a perl implementation have a look at:

The Win32 distribution has a php3_crypt.dll extension library which
provides the sflcrypt functions. But you have to call the encrypt
function instead. I still haven't figured out what the calling
parameters are, so if anyone knows, please be so kind as to post them 
here.
