wolfSSL Example Applications

============================



This repository contains example applications, written in C, which

demonstrate how to use the wolfSSL lightweight SSL/TLS library for secure

communication.



Each directory represents a unique topic (SSL/TLS, DTLS, PSK, etc.) and

contains a Makefile as well as a simple tutorial on the given topic.



## Current Examples



#### android (Android Studio and NDK Examples)



This directory contains examples that demonstrate using wolfSSL,

wolfSSL JNI/JSSE, and wolfCrypt JNI/JCE on the Android platform. Examples

use either Android Studio with Gradle or the Android NDK standalone toolchain.



Please see the [android/README.md](android/README.md) for further usage and 

details.







#### BTLE



This directory contains examples for securing a Bluetooth Low Energy Link (BTLE).

BTLE packets are small and throughput is low, so these examples demonstrate a

way to exchange data securely without BTLE pairing.



Please see the [btle/README.md](btle/README.md) for further usage and details.







#### can-bus



This directory contains an example echo server/client using wolfSSL over

CAN bus with an ISO-TP transport layer. It can be used with a virtual CAN bus

in Linux.

the main wolfSSL repository.



To generate your own cert text, see the [DER to C script](https://github.com/wolfSSL/wolfssl/blob/master/scripts/dertoc.pl).
