RSA (algorithm)

RSA is an algorithm that is used to securely transfer data. It uses mathematical equations and numbers to encrypt data so that it can't be read by someone who shouldn't have access. It works like this: first, two very large prime numbers are chosen. Then, those numbers are multiplied together, which creates a new number called an "RSA key". This key is then used to encrypt data (turn it into an unreadable jumble of letters and numbers) and send it to the other person. When the person on the other end receives the data, they use their own RSA key to decrypt the data and turn it back into something that can be read. This makes sure that the data remains secure while it passes from one person to another.
