CyaSSL is a C-language-based SSL library targeted for embedded and RTOS environments, primarily because of its small size and speed. CyaSSL supports the industry standards up to the current TLS 1.2 level, is up to 20 times smaller than OpenSSL, includes SSL client libraries and an SSL server implementation, includes an OpenSSL compatibility layer, and offers several progressive ciphers such as RABBIT and HC-128. Dual licensed under both the GPLv2 and standard commercial licensing, it caters to a wide range of projects.
Coretrace is a lightweight tool for debugging embedded Linux applications. It works by analyzing core files from crashed applications and outputs a short plain-text backtrace, suitable for putting into logfiles. The basic idea is to let the failing unit do self analysis of core files and report those back home during device maintenance lifetime. Non-interactive small-sized embedded systems are the primary targets, so small footprint is of major concern, since it will be stored on flash. Currently the compiled size is approximately 20 kb.
TorTV is a build of the Tor Project maintained to run on TV devices and set-top boxes so that anyone with such a household appliance can contribute to strengthen the Tor network. TorTV does not reimplement nor modify the Tor source code in any way; it provides binary builds for embedded targets and scripted bundles to facilitate their installation. So far, it targets WDTV devices running WDLXTV, but aims to grow to support more hardware in future.
