Re: NSE Scripts and SSL Cipher Checking

NSE would definitely be suitable. In fact, Nmap already has an NSE script to check SSL ciphers (ssl-enum-ciphers.nse), so you might want to take a look at that. This script doesn't check SSLv2 as there's a separate script for that (sslv2.nse). If you can find any ways to improve upon the current script, especially in terms of speed without affecting the accuracy, then I'm sure that'd be appreciated.

A while back I wrote athena ssl cipher check. It works by lying to the ssl server by pretending it supports all possible ciphers, sending large lists of ciphers then using a binary search tree. This enables it find all ssl possible ciphers and often faster than tools like HTC ssl cipher check.

I'm about that start working on the next version, and want to move away from Java. Initially I was considering a rewrite in C++, but I've been
hearing a lot of good things about NSE scripts lately.

Assuming the quality is upto standard, is this the kind of thing the nmap project would consider including as part of nmap? Is NSE suitable for this
kind of thing?
