Welcome to yaSSL.com

Home of yet another SSL. yaSSL is an SSL Library for programmers building security functionality into their applications and devices. yaSSL employs the dual licensing model, like MySQL, so it is available under GPL and commercial licenses. Support and consulting are also available for yaSSL. If you have an interest in porting yaSSL to an operating environment or host language we currently don't support, then please contact us, as we'd love to help.

IPV6 support and testing!

TaoCrypt can now be downloaded individually, a portable, fast, cryptographic library for most needs.

A C embedded version of yaSSL, CyaSSL is now available for download. This version is optimized for small footprint, both on disk and for memory use. The complete SSLv3/TLSv1.1 client/server footprint is under 60K, and smaller versions can be built. Features are still being added.
