Introduction
CyaSSL is a lightweight TLS/SSL library. It is used to add security, authentication, integrity and confidentiality to network communications.CyaSSL is about 10 times smaller than yaSSL, and can be up to 20 times smaller than OpenSSL (depending on the build configuration). User feedback also reports dramatically better performance when compared to OpenSSL in standard SSL operations.
CyaSSL's small size, speed and feature set make it ideal for use with FreeRTOS, but CyaSSL does not compromise on functionality. It supports the latest industry standards, such as the Transport Security Layer (TLS) protocol version 1.2, as well as progressive streaming and block ciphers such as HC-128, RABBIT, and NTRU.
FreeRTOS Integration Example
CyaSSL is already ported to FreeRTOS, and an example project is provided. The example runs in the FreeRTOS Windows simulator, allowing CyaSSL to be evaluated in a FreeRTOS environment from the convenience of a standard Windows computer, without the need for external target hardware.
Application Integration
CyaSSL is delivered as a set of ANSI standard C source files that can be added to any C project, and built with any ANSI compatible C compiler. Instructions for building CyaSSL with a cross compiler are contained in the user manual.CyaSSL has a simple API, and can be added into existing applications just as easily as it can be used in new applications. The Simple CyaSSL Client Side Usage Example and Simple CyaSSL Server Side Usage Example pages on this website demonstrate the steps necessary for a basic integration, and the provided FreeRTOS simulator example project can be used as a reference. The user manual contains a complete configuration and API reference.
