ciascun-m-annoja is a delayed-autodecryption computer program generator.
Delayed autodecryptions are programs that reveal a message, but only after some delay after executing it. By the properties of cryptographic hash functions, there is no way to obtain the message more quickly.
A simplified explanation is that the message is encrypted with a short password that was randomly generated but can be guessed with many repeated tries.
$ python3 generator.py
and follow the instructions. Enjoy!
