So, today someone asked a school question
AES-ECB chosen plaintext attack with long secret
Usually, I don't answer those but I decided to help the OP by giving some clues about how to solve the problem. To my dismay, other members started to down vote my answer without any explanations. I then decided to provide a full answer and members started to up vote my answer...
I felt like helping the OP but in the end, I'm not sure if it would have been better to do nothing and let him think. Just giving some clues was what I thought to be the best course of action but the harsh reaction make me think otherwise now...
Any guideline to follow?
