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

RSA Security Inc. unexpectedly released the widely used RSA public-key encryption algorithm into the public domain ahead of this week's expiration of the patent on the algorithm -- a move that's ...

A recent research paper makes the claim that the RSA cryptographic algorithm can be broken with a quantum algorithm. Skeptics warn: don’t believe everything you read.

RSA Security today released to the public domain an encryption technology patent that secures most of the e-business transactions taking place on the Internet. RSA's encryption algorithm has ...

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 ...

For example, this is used to support online shopping or secure messaging, traditionally using the RSA algorithm, though increasingly an alternative called elliptic curve Diffie-Hellman.
