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 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 ...

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

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.
