Simulazione di algoritmo RC4

The application demonstrates the working of RC4 algorithm, making use of flash animations. It simulates how values are passed in arrays, and makes a complex process easier to understand.

About RC4 :

RC4 is a stream cipher designed in 1987 by Ron Rivest of RSA Security. The source code of the algorithm was leaked on September 1994. The algorithm operates on a user selected variable length key (K) of 1 to 256 bytes (8 to 2048 bits), typically between 5 to 16 bytes. The master key is used to generate a 256-byte state vector S

Other variables used : Plaintext stream (P), Temporary Vector (T) and Index Pointers (i & j - 8-bit). The simplicity and speed of operation of RC4 made it one of the most widely used stream ciphers. It is widely used in applications such as SSL (Secure Socket Layer), WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access).
