One Time Pad - Applied Cryptography

[tedahd]

What is app for making the tutorial???Your pen, screen are all great...some information please.

You have C and S backwards. C is 1000011 and S is 1010011. Your code does not concatenate the results of each character. It prepends the results of each character.

Simple... get message character value (mcv) and one time pad character (otpc) values from a character set. ie. 'abcde' a=0, b=1 etc. Then to encrypt simply (mcv + otpc) - 1. To decrypt simply (ecv - otpc) + 1. The ecv is encrypted character value. If the result of a calculation is more than the character set length or it is less than 0, then mod the result by the character set length.

This was a great visual to supplement my textbook explanation.

DO YOU HAVE A VIDEO WHERE YOU EXPLAIN ABOUT TEA ENCRYPTION?

[ufoengines]

Cool! From time to time I on shortwave I hear classic number stations. Numbers spoken in Spanish in groups of five. Now you hear the verbal numbers with a modem sound/databurst? sound. Just how does that work?

[abelben]

are you writing on a screen in reverse?

[jeffreyweaver]

I'm sorry! I thought that this "one-time cipher pad" would have involved the old-school random letter generation sequences and something called a Vigenere grid, rather than a computer program!

[waasar]

There's a lot of python implementation details going on and not a lot of cryptography.

[UniverseGames]

Anyone run this code? Can you share the code, it's not working for me

[seanwilliamson]

That could have been explained in much simpler terms. Over academicised for the sake of it

[legocombo]

You should put int(n/2) in your def for converting into bits

[Chris-jxqr]

Beginning seems to have been cut off...

[babyboi]

ohhhh your talking about python, i thought you were actually explain the one time pad, I should of read the title

[Rachael-]

I don't speak math, this is taking me back to algebra 😰😰

[sohanagate]

+DCToblerone Thats what I thought too.
