Inter Process Communication Exercise

Practice the materials from this topic by implementing the projects presented below.

Reverse Encryptor Decryptor

Let's define "Reverse Encryption" (RE) as a technique for protecting text messages in which the text of the messages is reversed before they are sent further. Write a program reverse-encryptor-decryptor.c that has two processes communicating via an anonymous pipe (anonymous pipe).

The following rules must be valid for both processes:

• Parent process must read text from the keyboard, then apply the RE technique and send the encoded message to the Child process.

• Child process must wait for incoming messages, print the encoded messages to the screen, then decode them and store them in the file reverse-encryptor-decryptor.log.

Encrypted Chat

Write a pair of programs for server (encrypted-chat-server.c) and client (encrypted-chat-client.c). The server should mimic the behavior of the Parent process from the previous task, and the client should mimic the Child process respectively. The programs should use a named pipe (named pipe) as a communication method.
