RSA Cryptography

RSA cryptography is a secure method of encrypting information using two keys: a public key, which anyone can use to encrypt messages, and a private key, known only to the recipient, used to decrypt those messages. The security of RSA relies on the difficulty of factoring large prime numbers. When you want to send a secure message, you encrypt it with the recipient's public key. Only the recipient can decrypt it with their private key, ensuring that even if the message is intercepted, it cannot be read without access to the private key. This widely used method underpins secure online communication.
