# ESP-IDF port
## Overview
ESP-IDF development framework with wolfSSL by setting *WOLFSSL_ESPIDF* definition
Including the following examples:
simple tls_client/server
crypt test
crypt benchmark
The *user_settings.h* file enables some of the hardened settings.
## Requirements
1. ESP-IDF development framework
[https://docs.espressif.com/projects/esp-idf/en/latest/get-started/]
Note: This expects to use Linux version.
## Setup
1. Run *setup.sh* to deploy files into ESP-IDF tree
2. Find Wolfssl files at /path/to/esp-idf/components/wolfssl/
3. Find Example programs under /path/to/esp-idf/examples/protocols/wolfssl_xxx
4. Uncomment out #define WOLFSSL_ESPIDF in /path/to/wolfssl/wolfssl/wolfcrypt/settings.h
Uncomment out #define WOLFSSL_ESPWROOM32 in /path/to/wolfssl/wolfssl/wolfcrypt/settings.h
## Configuration
1. The *user_settings.h* for each example can be found in /path/to/examples/protocols/wolfssl_xxx/main/include/user_settings.h
## Build examples
1. See README in each example folder
## Support
For question please email [support@wolfssl.com]
Note: This is tested with "Ubuntu 18.04.1 LTS" and ESP32-WROOM-32.

#wolfSSL Example
The Example contains of wolfSSL benchmark program.
1. "make menuconfig" to configure the program.
1-1. Example Configuration ->
BENCH_ARG : argument that you want to use. Default is "-lng 0"
The list of argument can be find in help.
When you want to run the benchmark program
1. "make flash" to compile and load the firmware
2. "make monitor" to see the message
See the README.md file in the upper level 'examples' directory for more information about examples.

#wolfssl Example
The Example contains of wolfSSL tls client demo.
1. "make menuconfig" to config the project
1-1. Example Configuration ->
WIFI SSID: your own WIFI, which is connected to the Internet.(default is "myssid")
WIFI Password: WIFI password, and default is "mypassword"
Target host ip address : the host that you want to connect to.(default is 127.0.0.1)
Note: the example program uses 11111 port. If you want to use different port
, you need to modifiy DEFAULT_PORT definition in the code.
When you want to test the wolfSSL client
1. "make falsh monitor" to load the firmware and see the context
2. You can use <wolfssl>/examples/server/server program for test.
e.g. Launch ./examples/server/server -v 4 -b -i
See the README.md file in the upper level 'examples' directory for more information about examples.

#wolfSSL Example
The Example contains a wolfSSL simple server.
1. "make menuconfigure" to configure the project
1-1. Example Configuration ->
WIFI SSID : your own WIFI, which is connected to the Internet.(default is "myssid")
WIFI Password : WIFI password, and default is "mypassword"
When you want to test the wolfSSL simple server demo
1. "make flash" to compile the code and load the firmware
2. "make monitor" to see the context. The assigned IP address can be found in output message.
3. Once the server connects to the wifi, it is waiting for client request.
("Waiting for a connection..." message will be displayed.)
4. You can use <wolfssl>/examples/client to test the server
e.g ./example/client/client -h xx.xx.xx
See the README.md file in the upper level 'examples' directory for more information about examples.

The Example contains of wolfSSL test program.
When you want to run the benchmark program
1. "make menuconfig" to configure the program,first
1. "make flash" to compile and load the firemware
2. "make monitor" to see the message
