Platform and Language Support

CyaSSL is built for maximum portability, and is generally very easy to compile on new platforms. If your desired platform is not listed under the supported operating environments, please contact us.

CyaSSL supports the C programming language as a primary interface. It also supports several other host languages, including Java, PHP, Perl, and Python (through a swig interface). If you have interest in using CyaSSL in another programming language that it does not currently support, please contact us.

Commercial Support

Support packages for CyaSSL are available on an annual basis directly from yaSSL. With three different package options, you can compare them side-by-side and choose the package that best fits your specific needs. Please see our Support Packages page for more details.

Documentation:

CyaSSL is dual licensed under both the GPLv2 and commercial licensing. For more information, please see the following links.

Description

The CyaSSL embedded SSL library is a lightweight SSL library written in ANSI standard 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 as well because of its royalty free pricing and cross platform support. CyaSSL supports industry standards up to the current TLS 1.2 level, is up to 20 times smaller than OpenSSL, and offers progressive ciphers such as HC-128, RABBIT, and NTRU. User benchmarking and feedback reports dramatically better performance when using CyaSSL over OpenSSL.
