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

Some cryptographers are looking for RSA replacements because the algorithm is just one encryption algorithm that may be vulnerable to new machines that exploit quantum effects in electronics.

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

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 ...

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.

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.
