VL64 and B64 encoding functions ~ C++

This probably won't be of use to those of you who've moved onto the new crypto, but oh well.
Pretty self explanatory, it's a stable port of the VL64 and B64 encoding functions written by Jeax (I believe) and Jordan (his Java port provided the basis for this).
VL64 function

PHP Code:

---

static string Encode_VL64(int i){
    string s = "";
    char res[6]; //assign the var res to a a char array - len6
      int p = 0; 
 int sP = 0;
 int bytes = 1;
 int negativeMask = i >= 0 ? 0 : 4; //? : = if else clause
 i = abs(i);
 res[p++] = (char)(64 +(i & 3));
 for (i >>= 2; i != 0; i >>= 6){
     bytes++;
     res[p++] = (char)(64 + (i & 0x3f));
 }
 int null = 0;
 res[sP] = (char)(res[sP] | bytes << 3 | negativeMask);
  string tmp =  string(res);
tmp.erase(2,22); //clever little method to cut the string. 
//If this was not done, the output would have extremely weird chars.
  return tmp;

}

B64 function

PHP Code:

---

static string Encode_B64(int i){
string s = "";
 for (int x = 1; x <= 2; x++){
                s += (char)((char)(64 + (i >> 6 * (2 - x) & 0x3f)));
}
 return s;
} 


---

Usage:

PHP Code:

---

#include <iostream>
#include <string>
#include <math.h>
using namespace std;
int main()
{
int value;
cout << "Enter your value\n";
cin >> value;
cout << //either: Encode_B64(value) or Encode_VL64(value);
cin.get()
return 0;
}

Notes:
Don't go off releasing this under your name.
Option 3 will output "coming soon", due to native C++ not having certain classes and functions built-in.
Report any bugs here. (If you enter a string for menu selection, prepare for errors).

thank you ;D
Native C++ FTW!! ;D

Thank you, I forgot this part to add to mines :

Code:

---

tmp.erase(2,22); //clever little method to cut the string.
//If this was not done, the output would have extremely weird chars.

---

Also thanks for this :)

Great release Adil, saw some screenies on DB.

Has anyone tested it out?
What are your thoughts?

I converted them a few days ago into C++, but forgot some things like erase etc.
My opinion: Works great lol'd

Notes:
Updated build. Latest can be found at the same directory, http://jokercode.net/utils/packetscout++.zip

Updates:
-RC4 has been implemented. If you wish to encrypt something with RC4, please change:

Code:

---

rc4.Encrypt(key, "NV6VVFPoC7FLDlzDUri3qcOAg9cRoFOmsYR9ffDGy5P8HfF6eekX40SFSVfJ1mDb3lcpYRqdg28sp61eHkPukKbqTu1JsVEKiRavi04YtSzUsLXaYSa5BEGwg5G2OF");

---

to:

Code:

---

rc4.Encrypt(key, "your special key here");

---

The key variable is user input.

Problems:
-Dom has told me that my encryption is static, whereas the habbo rc4 encryption wasn't. You can use this for static RC4 encryption if you wish.

Thanks, this will come in handy!

Thanks ^^

I updated the build with decoding function. Instead of using a long winded char pointer to substitute for a char array, I've used strings.

Better nog make strings of them, bytes are better i guess.

Char arrays can't be initialized as empty in C++ (I think). If I use a char* pointer, the stack becomes overflowed :p

Sorry for the double post, but this is a note to any who used this.
I overlooked something. Some were complaining of a DLL error, which was caused due to them not having MS' C runtime library installed. The updated build should fix this. Link is the same as always:

Read the readme contained inside /dll

Ehm I don't know anything about Emulators, what's this?

It's an encoder/decoder written in C++ :laugh:
