The RSA algorithm is a feast of genius that combines theoretical math and practical coding into working asymmetric cryptography. Here’s how it works.

The RSA encryption algorithm uses a system of public and private keys to encrypt and decrypt messages. The public key is calculated by multiplying two very large prime numbers.

Internet security firm RSA warns customers not to use a community-developed encryption algorithm after fears it can be unlocked by the US National Security Agency.

A quantum computer with a million qubits would be able to crack the vital RSA encryption algorithm, and while such machines don't yet exist, that estimate could still fall further ...

The inventors of the RSA algorithm published a list of RSA keys and challenged people to find the original primes, as a way of tracking how secure the encryption is against modern computers.
