On the recipient’s side, which is peer B, it is going to decrypt the message using the private key and then verify the signature of the message using the public key of peer A which is the sender of the message. However, this method is signed using the private key of peer A, which is the peer sending the message. When peer A is sending a message to peer B, the message should be encrypted using the public key of peer B. If you have two peers i.e, peer A talking to peer B. In this tutorial, we have encrypted a message using a public key and signed it using our private key. With that, you can enter your message, encrypt, and then decrypt it. Print( 'The message signature could not be verified') Open your terminal and use the command below to install it: In this tutorial, we will be using rsa python package. However, for the private key, as the name suggests, it is kept private at the recipient’s side. The public key will be available in a public key repository. This is so that the receiver is the only one who can decrypt the message using their private key. The sender will encrypt the plain text with the recipient’s public key. 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. How the RSA encryption and decryption worksĮach pair of the RSA algorithm has two keys, i.e. I will be using Visual Studio Code for this tutorial. 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.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.
This is one of the major cyber security methods of data protection. RSA is a public key algorithm widely used for secure data transmission. 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.
This helps prevent data sent on the internet from unauthorized access. Data encryption is an important practice used to protect data transfer on the internet.
