Open source disk encryption with strong security for the Paranoid
VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a.
It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt.
This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase....
OpenFSL is an os-independent file system library. It provides file system control with customizable disk control. Currently supports MBR and FAT32 partially.
fast single-privilege single-address-space preemptive-multithreading persistent data-centric secure multiuser operating system with safe-language and reconfigurable graphical interface
Perix is a 16/32/64-Bit protected mode kernel, bootable and capable of running with or without an operating system. It is written in Turbo Pascal 7.0 for DOS, Delphi 7.0, Pascal Pro, Virtual Pascal v2.1, Delphi XE2 64-Bit, TASM, TASM32 and JWASM.
The latest version, 0.01I, supports multi-processor.
Added Open Watcom C++ and Borland C++ examples.
JNode is a Java New Operating system Design Effort.
JNode is a simple to use and install Java operating system for personal use on modern devices. Any java application runs on it, fast and safe.
See our homepage for additional information.
Derived from TrueCrypt 6.3 release, I added some command line options to "TrueCrypt Format.exe" to allow TrueCrypt volumes to be created without using the graphical user interface
Operating system project from scratch to design and implement all components from boot strapping,hardware interrupts , memory manger ,file system , etc .
The Trion Object Oriented Operating system is an OS that is designed to meet the needs for the 21st century, with a kernel written in C++ and modelled in UML, and lots of features. The project is run by a team of OSDev.org community members.

TriOS - The Object Oriented Operating System, is the next generation operating system. Fully based on object orientation, it brings unique features to programmers and end users. Basically everything in TriOS is an object, even files and programs! Enjoy!!
MEDDAC is the seeding point for designing a new approach to Operating System design itself. It is an Open Source project with roots in mainframe design and development the author began in 1979. Monitor Editor Disassembler Decompiler Assembler Compiler
The Banana Kernel is an open-source pedagogical operating system intended to provide useful means for teaching basic OS concepts, with the possibility of interaction with external modules developed by the teacher or student.
The FDOS Operaing System is 100% written in Assembler (NASM). It supports FAT 12, TSR and a small Multi Kernel System. The source is very good documentated (only in English). A German, russian and English Documentation (about 40 pages) are included.
The Fecundity Project has the purpose of creating a streamlined AMD64 based Operating System. We will hopefully create a stable and secure operating environment, and to investigate orthogonal persistence.
A Unix-like (Not compleatly Unix-compatible) Kernel. Right now, we have (very limited support) of 80486+ IBM-PC AT compatibles. Written in C, and assembly. No network support planned for the forseeable future.
SimplicityOS is a project designed to create a simple but powerful operating system for the pc. The kernel was designed from scrath to create a fast and stable base. The filsystem used by SimplicityOS was also designed from scratch for stability.
BiosDiskIO is a library of Int 13h PC BIOS Disk Operations. The primary purpose is to provide quick-and-dirty access to low-level disk services, especially for file system developers and forensic analysts.
ncurOS is a very secure OS, which is based on an UNIX (maybe linux) kernel. Many system tools are integrated in the kernel. All of these tools are written with ncurses. All ncurOS-developers follow a coding standard.
