RFC 2015 defines a proposed Internet standard for sending PGP-encrypted email. This PGP/MIME has been incorporated into several MUAs such as Mutt and (with the AEGYPTEN project) KMail. However, a lot of email clients still don't support it. pgp-mime-handler can decrypt/verify such messages via a pipe, so it can be used as an email filter in many programs or scripts.
libguestfs is a set of tools for accessing and modifying virtual machine (VM) disk images. You can use this for viewing and editing files inside guests, scripting changes to VMs, monitoring disk used/free statistics, P2V, V2V, performing partial backups, cloning VMs, and much more. libguestfs can access nearly any type of filesystem including: all known types of Linux filesystem (ext2/3/4, XFS, btrfs, etc.), any Windows filesystem (VFAT and NTFS), any Mac OS X and BSD filesystems, LVM2 volumes, MBR and GPT disk partitions, raw disks, qcow2, CD and DVD ISO images, SD cards, and dozens more. libguestfs doesn't need root permissions.
The pilot-link suite of tools contains a robust library and a series of conduits for moving information between your desktop or workstation and your Palm handheld device, such as those made by Palm, Sony, Handspring, Handera, and others. It also includes language bindings for languages such as Perl, Python, and Java.
Zinc is a Tk widget developed with Perl/Tk, Tcl/Tk and Python/Tk bindings. Zinc widgets are very similar to Tk canvases in that they support structured graphics. Graphical items can be manipulated, and bindings can be associated with them to implement interaction behaviors. But unlike the canvas, zinc can structure the items in a hierarchy, and has support for affine 2D transforms. Clipping can be set for sub-trees of the item hierarchy and the item set is quite more powerful, including field-specific items for Air Traffic systems. Zinc is fast enough to allow the implementation of 2k2k radar displays with smooth animations. It is structured enough to allow the implementation of direct manipulation desktop GUIs.
The Crate Game Engine is a game engine that is designed to make creating games trivial. The rendering and scripting engines are removed from the game engine to make the specialization of games as easy as possible. Currently, scripting support is implemented to allow a Lua script to be put directly in the game file, which can be validated as XML. Multiplayer text based adventure-style games can be played with the existing console rendering engine.
Config::Model::OpenSsh is a graphical configuration editor for OpenSSH configuration files (e.g. /etc/ssh/sshd_config, /etc/ssh/ssh_config, or ~/.ssh/config). Other user interfaces (curses and terminal) are also available. Programmers can choose to use the Perl API to modify or validate OpenSSH configuration. This program is based on Config::Model.
The Open Computer Forensics Architecture (OCFA) is a modular computer forensics framework to automate the digital forensic process, to speed up the investigation and give tactical investigators direct access to the seized data through an easy to use search and browse interface. The architecture forms an environment where existing forensic tools and libraries can be easily plugged into the architecture and can thus be made part of the recursive extraction of data and metadata from digital evidence. It aims to be highly modular, robust, fault tolerant, recursive, and scalable in order to be usable in large investigations that spawn numerous terabytes of evidence data and cover hundreds of evidence items.
MidWay is a service request broker. It provides a simple way for server programs to offer services, and for client programs to call the services. It is designed for maximum speed and scalability. MidWay consists of a library that gives programmers a simple API, and various runtime daemons.
