Implement in Go language AES encryption mode CBC with providing the packages name for Go language. You can implement AES-ECB Mode (the basic AES) from crypto/aes package and crypto/cipher.Block. You can also get the SHA-256 hash function from crypto/sha256. You can get the secure random numbers generator from crypto/rand package. However, the you will implement both CBC mode and HMAC from scratch. You are NOT allowed to use any libraries or packages to implement these two things for you. You...
