I need encrypt data with RSA using public key and decrypt using private key. Public and private keys generation not needed. I know that algorithm require computing resources, but I use only 32-128-bit keys or smaller. I can't find RSA lib for Arduino in internet.
I found cryptography AVR-Crypto-Lib library for AVR microcontrollers. How to use this library with Arduino? I think Arduino compatible, because it use ATmega328P, ATmega2560 microcontrollers etc. How include this library in Arduino IDE. It would be good that someone will write simple hello world example. Or can suggest other library that are implemented RSA algorithm.
