Sql2xml is a CGI program that lets you request a SQL query and convert it to JSON, CSV, XML or INI through a Web server. Sql2xml supports requests from multiple users and for multiple databases. It is intended for developers who do not have direct access to database servers due to firewalls or other restrictions.
LibHTP is a security-aware parser for the HTTP protocol and the related bits and pieces. That can mean many things, but the only scenario in which LibHTP has been tested so far is the one when you need to parse a duplex HTTP stream that you have obtained by passively intercepting HTTP traffic. Just feed the raw TCP stream to LibHTP and it will do the rest.
sec-wall is a feature-packed security proxy that supports SSL/TLS, WS-Security, HTTP Auth Basic/Digest, extensible authentication schemes based on custom HTTP headers and XPath expressions, powerful URL matching/rewriting, and an optional header enrichment. It's a security wall with which you can conveniently fence otherwise defenseless backend servers.
