read on wiki what a permutation is and shut up. with 5 letters there is 5! permutations to choose from and he just chose one of them to encrypt the message. the very fact that there are 5! permutations to choose from and that the attacker seeing the cyphertext doesn't know which one was used is the very idea behind the security of this encryption algorithm. think about it. if there was an agreed permutation that would be used every single time, then this wouldn't be an encryption algorithm at all, because the attacker could simply use the inverse permutation on the cyphertext and just read the message in plain text. but if the attacker doesn't know which permutation was used, but they know that the length of the permutation was 5, then they need to potentially check 5! permutations and waste some time (not very much these days but still) before they can break it.

@@Poppa certainly not by insulting the teacher. i was harsh because @saneleluthuli2188 was a dick. besides learning is not eating. you having questions after watching an introduction to a new topic is a natural thing to have. if you have questions you can ask them publicly, or do your own research, watch some other videos, connect the dots. being a dick about it and insulting the teacher is never the way to go.

Less talking more writing. Explanation unclear. Thumbs down.
