Unix crypt

[Guest]

Hi

I am trying to match a user password provided by a user on an ASP.NET web form with a Unix encrypted password stored in a Sybase database table. I know I cannot use MD5, SHA1, etc as the password is stored encryted in Unix, I guess crypt(). Is there a special Dll that I can use to convert the password into a Unix encrypted string value and then match the two values?

I am using ASP.NET, C#

Thanks

Sri.
