Hi,

I am brand new to google groups. I am currently a high school senior
(tomorrow is my last day of classes) and need to make 2 projects on
excel. After trying for a week, I was suggested to come here for help.
I need to make an excel program that is able to encrypt/decrypt letters
using a "Hill Cipher" and then another program using an "RSA
Algorithm," I have only been able to make excel do affine ciphers and
ceasar ciphers. I need these for later tonight if I anyone can help me.
This is for my cryptology course.
