BlueCrypt (2.0.0) for avr/megaavr by Aadruta PB

➡️ https://github.com/apbokkasa/BlueCrypt

A lightweight constant-time cryptographic library optimized for 8-bit AVR microcontrollers.

#ArduinoLibs #ArduinoLibraries #avrLibraries #megaavrLibraries
GitHub - apbokkasa/BlueCrypt: BlueCrypt V2 is a lightweight cryptographic library for 8-bit AVR microcontrollers (ATmega328P/Arduino UNO). Features dynamic 128-slot pipeline architecture, dual-mode non-linear S-Box (0-SRAM Flash PROGMEM default or SRAM override), 2-pass bidirectional diffusion, rolling 2-byte HMAC integrity verification, and simple dot-notation.
