CS 386 Project: Overview Project Synopsis: This group project will require your group to design and implement your own enciphering algorithm. Your team's algorithm must combine the two operations, substitution and permutation/transposition, into your unique encryption algorithm. Your encryption algorithm must include multiple rounds of the two operations. You program must be able to encrypt and decrypt messages. Your team will need to give your algorithm a name that is unique to your encryption technique. Your group may
