Encryption and Decryption using C++

Overview

By the end of this project, you will be able to create a basic application using Vigenere encryption-decryption technique to encrypt and decrypt messages. Throughout the project, you will be able to identify the basics of cryptography and how to encrypt and decrypt messages using a specific technique, you will be able to apply concepts like ASCII codes and type casting. Moreover, you will be able to do some mathematical operations on characters, and finally you will be ready to dive more into the cryptography world.

This guided project is for beginner programmers or any programmer who would like to enter the cryptography world. This project will be the beginning for you to build applications to encrypt and decrypt messages coming from the user using a certain technique. This project will give you the basic knowledge of cryptography and push you into the security engineering field.

Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.

Advantages and disadvantages

Advantages

  • Structured courses with graded quizzes, assignments and deadlines you can reset.
  • A shareable certificate from the university or company when you pay.
  • Financial aid is often approved for students in India (apply 15 days before you need it).
  • Self-paced: start any time.

Disadvantages

  • Paid after a 7-day free trial (Coursera Plus or per course).
  • Some courses can be audited for free, but graded work and certificates need payment.
  • Short (1 hour and 10 minutes): an overview, not deep coverage.

Some points apply to every course of this kind; see how we rank.

This course is paid. Here is how to take it for free

  • Free trials: You can start a 7-day free trial for many individual courses, Specializations, or a Coursera Plus subscription to test full course features. Cancel before the seventh day if you do not want to be charged.
  • Financial aid: If you cannot afford the fee for a certificate, you can apply for financial aid through the link on the course home page by filling out an application about your background and goals.
