sir please explained other substitution techniques Monoalphabetic Ciphers Hill Cipher Polyalphabetic Ciphers One-Time Pad

Well explained❤️❤️❤️

Thank you

thanks for your effort, just one comment. instead of swapping between L&R which may consume more time why just suggest to swap the F. so, it will apply once for R and in the 2nd R the F will apply for L etc. can be applied or not. thanks again.

Thank u so much sir please explain RSA

First of all I would like to congratulate you for your videos! When you say plaintext, since we are talking about block ciphers, you refer to a single block of plaintext, right? Not the initial plaintext.

Thank you. The class I am taking just had a diagram of the structure but no context as to what any of it means.

Thank you so much!
