Pixane is an image processing library for Tcl that allows the scripting of all kind of image transformations. It supports reading from and writing to a large set of file formats (JPEG, PNG, GIF, BMP, WBMP, etc) and provides anti-aliased text rendering and a set of built-in fonts. It doesn't requires Tk, so it can be used to easily generate images dynamically from CGI. Binaries are provided for many platforms as dynamic libraries with no external dependencies for easy deployment. It is also a core component of the eTcl distribution.
nsmcrypt is an AOLserver module and standard Tcl library that implements an interface to the mcrypt library (libmcrypt). It supports cipher algorithms (such as blowfish, des, or rijndael-256), cipher modes (such as cbc, cfb, ncfb, or stream), and also supports sharing with nsv_* commands. It was tested with AOLserver 3.4.x and 4.0.x and Tcl 8.4.
nsmhash is an AOLserver module and Tcl package that implements an interface to the mhash library (libmhash). It supports hash, hmac, and key generation algorithms (such as SHA1, MD5, MCRYPT, and S2K_SALTED), and it also supports sharing with nsv_* commands. It was tested with AOLserver 3.4.x and 4.0.x and Tcl 8.4.
sendPGPMail.cgi is a small CGI script for sending an encrypted PGP email message to a predefined receiver from an HTTPS secured Web page. The typical use of this script is to provide the users of a secure Web site the possibility to send a secure email to a predefined employee of a company. The CGI script gets its input from an HTML form and passes it on to gpg. The message and its attachments are encrypted using the PGP public key of the predefined receiver.
Apache Rivet is a system for creating dynamic Web content via a programming language integrated with Apache Web Server. It is designed to be fast, powerful and extensible, consume few system resources, be easy to learn, and to provide the user with a platform that can also be used for other programming tasks outside the web (GUIs, system administration tasks, text processing, database manipulation, XML, etc.). It is similar to PHP, except that it uses Tcl, and provides both HTML/Tcl pages as well as pure Tcl pages to aid the programmer in separating logic and presentation when necessary.
