Design your software/system with at least three layers: 1. Application layer – you choose your own application that uses all the functions in the cryptographic algorithm layer. 2. Communication layer – two or more devices exchange messages. 3. Cryptographic algorithm layer – public key based and symmetric key based encryption and decryption functions, digital signature, and hash functions. Your program needs to include:  One implementation of a public key based encryption and decryption function.  One implementation of symmetric key based encryption and decryption function.  Usage of the built-in public key based and symmetric key based encryption and decryption functions, digital signature, and hash functions.
