wolfSSL Year In Review -

wolfSSL, author of the open source CyaSSL embedded SSL library has made significant progress in 2013 towards bringing the community a more usable, feature-rich, and better supported library for use in an ever-growing range of embedded platforms and environments. This talk will provide an overview of technical progress in the last year and news on the current state of wolfSSL. Details on what's new include the addition of new crypto ciphers and algorithms, better hardware cryptography support, more flexible abstraction layers, a JNI wrapper, new platform support, and better development tool integration. www.wolfssl.com
