Mimic ASP.NET web forms encryption method using php
<p>I've tried searching a lot but so far everything seems to be about hashing.</p>

<p>I have a database with users created using the .net web forms framework. In web.config it is set to the encryption method to store users' passwords. I also see a validation and decryption key.</p>

<p>If I have access to these encrypted values in PHP, how can I encrypt a user given password to match against the stored encrypted copy?</p>

<p>Thanks,
Mike</p>
