SharkSSL-Lite

Description: SharkSSL is an SSL v3.0 TLS v1.0/1.1/1.2 implementation of the TLS and SSL protocol standard. With its array of compile-time options and Raycrypto proprietary cryptographic algorithms, SharkSSL can be fine-tuned to a footprint that occupies less than 20 kB, while maintaining full x.509 authentication. The SharkSSL-Lite download includes a subset of SharkSSL and header files made for use in non-commercial and for evaluation purposes.

Features

Examples

Limitations

SharkSSL-Lite includes a limited set of ciphers. To use SharkSSL-Lite, the peer side must support Elliptic Curve Cryptography (ECC) and you must use ECC certificates. The peer side must also support the new ChaCha20/Poly1305 cipher combination.

ChaCha20 and Poly1305 for TLS is published RFC 7905. The development of this new cipher was a response to many attacks discovered against other widely used TLS cipher suites. ChaCha20 is the cipher and Poly1305 is an authenticated encryption mode.

SharkSSL-Lite occupies less than 20kB, while maintaining full x.509 authentication. The ChaCha20/Poly1305 cipher software implementation is equally as fast as many hardware accelerated AES engines.

Creating ECC Certificates for SharkSSL-Lite

The following video shows how to create an Elliptic Curve Cryptography (ECC) certificate for a server, how to install the certificate in the server, and how to make the mbed clients connecting to the server trust this certificate. The server in this video is installed on a private/personal computer on a private network for test purposes. The video was produced for the embedded.com article How to run your own secure IoT cloud server.
