hwcrypt demo program

[nottledim]

I've been struggling up the learning curve of encrypting some arbitrary data for sending for example over a LoRa connection.

In case there's anybody else in a similar situation I've written a simple demo program that runs under esp_idf on a esp32 module.

It creates necessary data structures and data and then encrypts to a buffer using AES_CBC and then decrypts it back to the beginning.

It can be found at: https://gitlab.com/nottledim/demo_esp_aes

If there's anything not right right let me know. Thanks
