Collection of strong crypto libs that can be included in Arduino-core for ESP8266
- curve25519-donna : strong ECC key agreement function
- esp8266-trng : simple wrapper to the HW TRNG
- sha256 : SHA2-256 class
All these libs require that you already have:
- installed Arduino IDE for your platform; minimum release tested is 1.6.5, but should work with anything 1.5+
- installed the Arduino-core
- applied the patch if you get an error about iram0 filling up when you compile an example
- copied the lib you need under the right folder (~/Arduino/libraries in Linux)
