The CyaSSL embedded SSL library is a lightweight SSL library written in ANSI C and targeted for embedded and RTOS environments, primarily because of its small size, speed, and feature set. It is commonly used in standard operating environments and cloud services as well because of its royalty-free pricing and excellent cross platform support. CyaSSL supports industry standards up to the current TLS 1.2 and DTLS 1.2 levels, is up to 20 times smaller than OpenSSL, and offers progressive ciphers such as HC-128, RABBIT, and NTRU.
yaSSL is a C++ based SSL library for embedded and RTOS environments, designed for individuals who prefer to use the C++ language. For a C-based solution, please see CyaSSL. yaSSL supports the industry standards up to TLS 1.2, and also includes an OpenSSL compatibility interface.
Wt is a C++ library for developing Web applications with an API that is widget-centric and inspired by existing C++ graphical user interface APIs. To the developer, it offers abstraction of Web-specific implementation details, increasing the accessibility and portability. Under the hood, the library uses the latest techniques (HTML5, Ajax, WebSockets) to handle user events and update the Web page.
Fakeroot-ng runs a program while fooling it into thinking it is running with root privileges. When the program does something that only root can do (e.g. create a device file), fakeroot-ng emulates the appropriate system calls so that the program gets a consistent view of its actions. Unlike the original fakeroot, fakeroot-ng uses the ptrace interface, which means that it does not suffer some of the limitations that fakeroot does. In particular, fakeroot-ng supports chroot jails.
amforth is an extendible command interpreter for the Atmel AVR ATmega microcontroller family. It has a turnkey feature for embedded use as well. It does not depend on a host application. The command language is an almost compatible ANS94 forth with extensions. It needs less than 8KB code memory for the base system. It is written in assembly language and forth itself.
crosstool-NG is a versatile toolchain generator, aiming at being highly configurable. It supports multiple target architectures, different components (glibc/uClibc...) and versions. crosstool-NG also features debugging utilities (DUMA, strace...) and generation tools (sstrip...).
NETSHe is a feature-rich and general-purpose Web interface and initialization system for OpenWRT-based firmware. Its main features are network interface management (including point-to-point and wireless), VLANs and aliases, advanced routing (static, multipath, rule-based, RIP, OSPF, BGP), a zone-based firewall, bridges with brouter and filtering capability, interface bonding, quality of service, bandwidth management, traffic shaping, rate control, traffic prioritization, L7 based IP traffic filtering and marking, extended management of wireless interfaces, an access concentrator for variable VPNs (PPTP, L2TP, and OpenVPN), and much more.
KLone is a fully-featured, multi-platform framework which allows dynamic Web pages to be written in C/C++ (with the usual <% /* code */ %> style). The pages can then be embedded (in compressed and/or encrypted form) into a single executable that also contains KLone's high-performance HTTP/S server. Given its nature, it can be linked natively to any C/C++ library (database, XML, graphics, etc.), without an intermediate layer, and it is especially suited for low-resource (embedded) systems.
PolarSSL is a light-weight cryptographic and SSL/TLS library written in C. PolarSSL makes it easy for developers to include cryptographic and SSL/TLS capabilities in their (embedded) applications with as little hassle as possible. Loose coupling of the components inside the library means that it is easy to separate the parts that are needed, without needing to include the total library. PolarSSL is written with embedded systems in mind and has been ported on a number of architectures, including ARM, PowerPC, MIPS, and Motorola 68000. The source is written to have very loose coupling, enabling easy integration of parts in other software projects. Very loosely coupled cryptographic algorithms for MD2, MD4, MD5, SHA1, SHA-256, SHA-512, AES, Camellia, DES, Triple DES, ARC3, and RSA are included.
