Welcome to the Level 3 RSA course! In this article, we will delve deep into the topic of RSA encryption, a fundamental concept in cryptography. RSA encryption is widely used to secure data transmission and protect sensitive information. Let's explore how RSA works and why it is essential in today's digital world.
RSA encryption is a public-key encryption algorithm named after its inventors, Ron Rivest, Adi Shamir, and Leonard Adleman. It is based on the mathematical properties of prime numbers and modular arithmetic. RSA encryption uses two keys, a public key for encryption and a private key for decryption.
When a message is encrypted using RSA, it is scrambled using the recipient's public key. Only the recipient, who possesses the corresponding private key, can decrypt the message and read its contents. This asymmetric encryption scheme ensures secure communication over insecure channels.
