This includes not only RSA <https://en.wikipedia.org/wiki/RSA_(cryptosystem)> whose security rests on factoring primes, but also the discrete logarithm problem which is the foundation of Diffie-Hellman <https://en.wikipedia.org/wiki/Diffie%E2%80%93Hellman_key_exchange> key exchange and elliptic curve cryptography <https://en.wikipedia.org/wiki/Elliptic-curve_cryptography>.
