RSA Algorithm

RSA is a method for securely sending messages. It uses two keys: a public key (shared openly) for encrypting messages and a private key (kept secret) for decrypting them. When someone wants to send a secure message, they use the recipient’s public key to transform the message into an unreadable form. Only the recipient’s private key can revert it back to the original message, ensuring privacy. This relies on the difficulty of factoring large prime numbers, making it highly secure. RSA is widely used in online secure communications like HTTPS, ensuring data remains confidential.
