An public-key encouraging technology developed by RSA Data Security, Inc. The acronym stands for Rivest, Shamir, and Adelman, the inventors of the technique. The RSA algorithm is related to the truth that there is no efficient way to factor very large numbers. Deducing an RSA key, therefore, requires an extraordinary amount of computer processing power and time. The RSA algorithm has become the de facto standard for industrial-strength encryption, particularly for data sent over the Internet. It is develop into many software products, consisting Netscape Navigator and Microsoft Internet Explorer. The technology is so powerful that the U.S. government has restricted exporting it to foreign countries. An exact technology that is also used widely is offered by a company called Cylink.
