Subject: Re: Fuzzing with regular expressions

Hi Dhiru,

I suppose rexgen is (and will be) slower than maskprocessor, as it is not
optimized for password generation. But rexgen is more flexible, as it
generates values based on regular expressions. My first intent was to use
it as fuzzing tool for web services (which was indeed the starting point
two years ago). This is also the reason why
 - there is a lua interface: rexgen shall be used whithin NMap Scripting
Engine efficiently
 - there is a backreference operator, which you can use to fuzz XML content
(or other context-free content)

I hope this answers your question...

Kind regards, Jan
