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

Encryption is essential for protecting data, with both symmetric and asymmetric methods offering unique advantages.

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 ...

RSA's encryption algorithm has powered nearly all the locks that appear in a Web browser when it enters a secure area. The patent was issued to the Massachusetts Institute of Technology nearly 20 ...

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.

RSA Security says it has released its public key encryption algorithm into the public domain, waiving its patent rights.

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.

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.
