This article explains how RSA encryption adds an extra layer of security to sensitive data beyond HTTPS. While HTTPS protects data in transit, RSA encryption helps guard against risks like MITM attacks, compliance issues, and replay attacks. The process involves the back-end generating RSA key pairs, sending the public key to the front-end, and the front-end encrypting data before sending it back for decryption. By securely managing keys with cache expiration, RSA ensures sensitive data remains protected throughout communication.
