Data encryption is an important practice used to protect data transfer on the internet. This helps prevent data sent on the internet from unauthorized access. One of the major algorithms used for data protection on the internet is the Rivest, Shamir, and Adleman (RSA algorithm), named after the inventors of this encryption and decryption algorithm. RSA is a public key algorithm widely used for secure data transmission. This is one of the major cyber security methods of data protection. The below code will generate random RSA key-pair, will encrypt a short. How the RSA encryption and decryption works.In this tutorial, we will discuss the working of the RSA algorithm and how this algorithm can be implemented in Python. Now lets demonstrate how the RSA algorithms works by a simple example in Python. You can download either Pycharm or Visual Studio Code A code editor installed and well set up.Basic knowledge of the Python programming language.To follow along with this tutorial, you need to have: Implementing the RSA algorithm in Python. I will be using Visual Studio Code for this tutorial. How the RSA encryption and decryption worksĮach pair of the RSA algorithm has two keys, i.e. One key is used for encrypting the message which can only be decrypted by the other key.įor instance, let’s say we have two peers communicating with each other in a channel secured by the RSA algorithm. The sender will encrypt the plain text with the recipient’s public key. This is so that the receiver is the only one who can decrypt the message using their private key.
