Ceasar’s cipher is neither complex nor an OTP. What are you talking about?

What are you talking about. That was the first cipher.

RSA is OTP?

The point originally made was that RSA couldn't practically be used because of how complex the math is to do by hand. So, the parent is pointing out that the Caesar cipher isn't a counterargument.

In other words, the "inconvenience" of doing a Caesar cipher by hand is nowhere near comparable as doing an RSA cipher by hand.

Is not complex at all, if you can't multiply two prime number and do subtraction probably you should reconsider your skills.

If people were able to do that in 15th century by hand I don't see how who really needs it couldn't.

Is just the needs were different, but is not complicated

Otp
