Not sure if this is possible, but has anyone seen (or know how to do)
emulation of the PHP "crypt" function from within c#?

Thanks

Are you just trying to do cryptography in general, or does it have to
match the exact format/functionality of PHP's "crypt" function?

Ideally I want to be able to "crypt" a string in a c# app, and get the same
hash that a bit of php code on a webserver would generate... I'll have a
play with the built in .net stuff and see what comes out I guess...
Thanks

Unfortunately it looks like that could vary significantly:

If you can work out exactly which one you want to support, the rest is
probably easy :)

According to http://www.phpbuilder.com/manual/en/function.crypt.php
the PHP cryp() function may use either DES or MD5. Both of these are
available in .NET

There is also such a thing as a PHP .NET complier. In a pinch you could
incorporate it that way, but I'm not sure what other PHP runtime components
are required.

See http://www.php-compiler.net/doku.php
