anyone used base64.h in a c++ program?

i am trying to convert username and password to base64 but for some reason i am getting a few compile errors, i think i have only the linux version of .base64.h and base64.cpp and not the windows one , can anyone help , TY

Code:

---

        string username = "myusername";
        string passwd = "mypassword";
        char src[100];
        char GetBuffer[100];
        sprintf(GetBuffer,"%s%c%c",username,':',passwd);
        char *Encoded = encode_base64(sizeof(GetBuffer),(unsigned char *)GetBuffer); //this function is in base64.cpp , the problem is its not compiling properly

---

What are the compiler errors?

error C3861: 'encode_base64': identifier not found

i look in the .h and dont even see this funciton name

Code:

---

class Base64
  {
    public:
      static std::string encode(const std::string & data);
      static std::string decode(const std::string & data);
      static std::string encodeFromArray(const char * data, size_t len);
    private:
      static const std::string Base64Table;
      static const std::string::size_type DecodeTable[];
  };

There is something wrong here - %s is for c-strings
maybe username.c_str() could help

%c and password do not work together at all

And why do you try to ancode the whole buffer, while only part of it could contain data?

so why are you trying to use internal function that is not been provided as external API?

so i am trying to access a page that needs login so instead of using base64 from the source i just use a convertor

char *Http = "GET /index.php/ HTTP/1.1\r\nHost: www.somesite.com\r\n\r\n""Authorization: Basic XXXXXXXXXXXXXXXX"; //so this means i dont have to login???

this is nothing malicous i am just trying to parse forum posts from a site :D

Way to go. You had a base64 encoded string baring your username and password for this site. I logged into your account and removed it for you. Be careful - other people might to more malicious things. I hope I was quick enough for you ;).
So yes, the base64 encoding was fine :P

so why dosent it work?

Okay, now I actually looked at your post a bit closer, a few things:
Are you sure you need that kind of authorisation? Most forums don't use HTTP auth, but rather a normal login and a cookie to keep your session's information.

But if you can, indeed, use http authentication... The Authorization header is... a header ;). So it should be before the \r\n\r\n. There should be a single \r\n, followed by a \r\n\r\n after the authorization header.

well i aso use another way which the reponse is , thanks for logging in

sprintf(body,"vb_login_username=Anddos&cookieuser= 1&vb_login_password=&s=&do=login&vb_login_md5passw ord=34507f68ddd44f5c1fr99c9ed5e73644& vb_login_md5password_utf=34507f68ddd44f5c1f299c9ed 5e73644");
sprintf(headers, "POST /login.php?do=login HTTP/1.1\r\nHost: www.somesite.com\r\n"
"Connection: Keep-Alive\r\n"
"KeepAliveTimeout: 15\r\n"
"Content-Type: application/x-www-form-urlencoded\r\n"
"Content-Length: %i\r\n\r\n", strlen(body));

after this i dont know how to use GET to get the pages i should be able to access after logging in, it just seems to loose connection or something

You just don't learn do you..? I mean, posting your password in base64 format is really bad and granted, posting it md5 is a little bit better. But it's still bad - and brute forceable.

I suggest you change your password asap ;)

this code works perfect, the trouble is after this , i cant do anything....

        sprintf(headers, "POST /login.php?do=login HTTP/1.1\r\nHost: www.site.com\r\n"
                            "Connection: Keep-Alive\r\n"
                                        "KeepAliveTimeout: 15\r\n"
                    "Content-Type: application/x-www-form-urlencoded\r\n"
                                        "Content-Length: %i\r\n\r\n", strlen(body));

oh and the dude say about my password , well so what i didnt think of changing it at the time , why would you want to abuse a forum account ...

anyone after this request it logs in fine , after that i do
char *index = "GET /index.php HTTP/1.1\r\nHost: www.site.com\r\n;
send(sock,index,strlen(index),0); after this recv goes to 0 .....
