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.
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.
