WebJun 3, 2014 · RC4 is implemented in two main phases: 1. A Key Scheduling Algorithm is executed using a symmetric key to create an array of 256 bytes (0x100h). 2. This array is then used in a pseudo-random number generation algorithm to generate a cipher stream that can be decoded using the same key. WebRC4 has become part of some commonly used encryption protocols and standards, including WEP and WPA for wireless cards. The main factors in RC4's success over such a wide range of applications are its speed and simplicity: efficient implementations in both software and hardware are very easy to develop. fAnalysis of RC4.
