We wanted the library, no one else did it,
we decided to take a shot. After going 
through numerous libraries this was the 
only one that worked with ephemeral 
diffie-hellman ciphers (glftpd).

FTP/SSL for .NET is a versatile file-
transfer component for .NET languages 
(such as C# or VB.NET). It allows you to 
transfer files directly from your 
application using FTP/SSL, an extension of 
FTP which is fast becoming a standard for 
secure FTP. This protocol is also known as 
FTPS or FTP over TLS and is defined by RFC 
4217. The name Secure FTP is used to refer 
to this protocol as well, although this 
can also mean SFTP, which is a different 
protocol that runs over SSH - we provide 
an SFTP component  as well.

Instructions: copy the libraries provided 
in crack over to the installation folder.

Dont really expect this to be a regular 
thing, just enjoy :)
