Prime Factors and Encryption. Cryptography is an essential aspect of modern society. Computers transfer data to other computers all over the world every nanosecond of every day. Threats to the security and accuracy of information pathways challenge hardware and infrastructure improvements as fast as they are conceived.
RSA (Rivest–Shamir–Adleman) is an algorithm used by modern computers to encrypt and decrypt messages. It is an asymmetric cryptographic algorithm. Asymmetric means that there are two different keys.This is also called public key cryptography, because one of the keys can be given to anyone.The other key must be kept private. What is a prime number? Prime numbers and cryptography. Encryption always follows a fundamental rule: the algorithm -- or the actual procedure being used -- doesn't need to be kept secret, but the key does. Even the most sophisticated hacker in the world will be unable to decrypt data as long as the key remains secret -- and prime numbers are very useful for creating Usenet Prime Anniversary Special Prime speed allows you to saturate the full bandwidth of your broadband connection for truly remarkable speed.

Guidance for organisations wishing to deploy or buy network encryption, using IPsec. RSA (cryptosystem) - Wikipedia RSA (Rivest–Shamir–Adleman) is one of the first public-key cryptosystems and is widely used for secure data transmission. The acronym RSA is the initial letters of the surnames of Ron Rivest, Adi Shamir, and Leonard Adleman, who publicly described the algorithm in 1977.In such a cryptosystem, the encryption key is public and distinct from the decryption key which is kept secret (private).
The RSA encryption algorithm which is commonly used in secure commerce web sites, is based on the fact that it is easy to take two (very large) prime numbers and multiply them, while it is extremely hard to do the opposite - meaning: take a very large number, given which it has only two prime factors, and find them.
