Cao Safety Text This is the first, not the last, encryption system created by Cao in Scratch. It is designed to be fast and efficient. Of course, it is not as resistant as modern methods such as AES-256 or others, but it is significantly simpler to implement and still provides effective protection in Scratch. So, I challenge you to decode these 3 encrypted messages: Lv1. Simple level (Deep 1) Lv2. Medium level (Deep >1 but <5) Lv3. Hard level (Deep >5)
