[QUOTE="Adil, post: 154315, member: 3031"] Here it is... [CODE] #include <iostream> #pragma once // RC4.h // Contains definitions for functions to be used in RC4.cpp typedef unsigned char byte; class RC4 { public: RC4(void); ~RC4(void); void Init(byte tKey[]); void swap(int,int); void parse(byte t[]); private: int i; int j; int table[256]; }; [/CODE] RC4.cpp [CODE] #include "RC4.h" RC4::RC4(void) { } RC4::~RC4(void) { } void RC4::Init(byte *tKey) { int len = sizeof(tKey)/sizeof(byte); this->i = 0; while(this->i < 0x100) { this->table[this->i] = this->i; this->i++; } this->i=0; this->j=0; while(this->i < 0x100) { this->j = ((this->j + this->table[this->i]) + (tKey[this->i % len] & 0xff)) % 0x100 ; this->swap(this->i,this->j); this->i++; } this->i=0; this->j=0; } void RC4::swap(int a, int b) { int x = this->table[a]; this->table[a] = this->table[b]; this->table[b] = x; } void RC4::parse(byte *k) { int x = sizeof(k)/sizeof(byte); for(int a = 0; a < x; a++) { this->i = (this->i+1)%256; this->j = (this->j + this->table[this->i]) % 256; this->swap(this->i,this->j); k[a] = (byte)((k[a] & 0xff) ^ this->table[(this->table[this->i] + this->table[this->j]) % 256]); } } [/CODE] I have not tested it as of yet. It is a direct port of Itachi's Java release. Sorry for the lack of documentation, this was written quite quickly. Have fun! [/QUOTE]
