20 Facts About RSA cryptosystem

An RSA cryptosystem user creates and publishes a public key based on two large prime numbers, along with an auxiliary value.

Security of RSA cryptosystem relies on the practical difficulty of factoring the product of two large prime numbers, the "factoring problem".

Idea of an asymmetric public-private key RSA cryptosystem is attributed to Whitfield Diffie and Martin Hellman, who published this concept in 1976.

RSA cryptosystem spent the rest of the night formalizing his idea, and he had much of the paper ready by daybreak.

RSA cryptosystem's discovery was not revealed until 1997 due to its top-secret classification.
