Marcena, nice job explaining what a concealment cipher is and what it does. It was well written for those none “technical” people to understand. I think you did an excellent job of explaining the basic features of the cipher.

One thing that I found interesting about symmetric ciphers is how many there are and that they have been used for such a long period of time. I guess people have always had a need to keep information and data safe and encrypted.
