RSA (Rivest-Shamir-Adleman) Algorithm

RSA (Rivest-Shamir-Adleman) is a widely used encryption algorithm that secures data transmitted over the internet. It relies on the mathematical difficulty of factoring large prime numbers. In RSA, each user has a pair of keys: a public key, which anyone can use to encrypt messages, and a private key, which only the user knows and is used to decrypt received messages. This ensures that even if someone intercepts the message, they cannot read it without the private key. RSA underpins many security protocols, such as HTTPS, making online communication safer.
