How come 26! for the word NESO to break it would take - 26 X 25 X 24 X 23 permutations right??

Sir, How would we decrypt after encrypting, because youve given us secret key: the quick... now how would we get the plain text back from the cipher text

Didnt you forget to talk about the key in monoalphabetic sub? just rambling the letters around makes no sense, then there is no way to decrypt

8:30 How come we have 4! possibilities? We would have 26 options for 1st letter, 25 for the 2nd...and so on...So, possibilities = 26*25*24*23

But monoalphabetic technique is a SUBSTITUTION technique, then why permutation?, isn't substitution of letter is done here?

12:44 what if the cyphertext and plaintext is not a didactic example, but real ones :(.

Conclusion: watch these tutorials to discover state secrets.
