Divisibility and PrimesCrypto

COMING SOON – RSA example with Alice and Bob

This encryption algorithm is called RSA Cryptography, after its three inventors, Ron Rivest, Adi Shamir and Leonard Adleman who published it in 1977. It turns out that a very similar method was known to the British Secret Service since 1973, but remained classified until much later.

Today, prime numbers are used by computers all over the world to exchange data. As you browse the internet or send chat messages, your phone or laptop will quietly generate large prime numbers and exchange public keys with other computers.
