Hi,
I've already add the following lines at the end of the AES_Decrypt function, and still didn't work

int g = strlen(Decrypted_Message2);
char * DEC_msg2 = new char[g+1];
strcpy(DEC_msg2,Decrypted_Message2);

return DEC_msg2;

I've tried running both debuggers at the same time on C++ Builder XE3, but it didn't work.
You were right, the problem was on the client-side, in which the encryption occurs.
I fixed the problem by generating the session key and the IV within the same Client-socket function, instead of having their own functions. next, I performed the encryption process.

is it possible to run the debugger on two different projects at the same time?, as the client and the server needs to operate together.

Thank you so much.
it worked.
you've been very helpful.

Best regards.

yes the certificate is on my Mac's Desktop.

So, do you mean I have to install the certificate on my iPhone?

Hello again,
What do you mean by "writing the bytes from the image file"?

Regards.

raniam 22-Apr-14 11:37am View

Hello,

I've tried it your way, but got lots of syntax errors.
but when I write it this way:
if (snorkel_printf (outstream, "<html><body>

<img src=<c:\users\rania\documents\images\qr4.jpg alt="QRcode" width="178" height="178">"
"

</body></html>\r\n")== SNORKEL_ERROR)
return HTTP_ERROR;

return HTTP_SUCCESS;
}
no errors, and I get the Image box, but with a black X inside of it, and QRcode written inside of it, but no image, I wonder why?

Regards

hello,
the following code snippet works fine, all I have to do, is to run the c++ program, and open the browser and write http://localhost:80

#pragma hdrstop
#pragma argsused

#include <snorkel.h>
#include <tchar.h>
#include <stdio.h>
#include <stdlib.h>

call_status_t index_htm(snorkel_obj_t http, /*read environment from this object */
snorkel_obj_t outstream) /* write data to the output stream */
{
if (snorkel_printf (outstream,"<html><body>

Dynamic Content"
"

</body></html>\r\n") == SNORKEL_ERROR)
//if (snorkel_printf (outstream,"<html><body><img src="QR4.jpg" alt="QR code" width=178 height=178</html>\r\n")== SNORKEL_ERROR)

return HTTP_ERROR;

return HTTP_SUCCESS;
}

void syntax (char *pszProg)
{
fprintf (stderr, "syntax error:\n");
fprintf (stderr, "%s [-p <port>]\n", pszProg);
exit (1);
}

void main (int argc, char *argv[])
{
int i = 1;
int port = 80;
snorkel_obj_t http = 0;

{
char carg = argv[i][1];
switch (carg)
{
case 'p': /* port number */
port = atoi (argv[i + 1]);
i++;
break;
default:
syntax (argv[0]);
break;
}
}
}

/*

if (snorkel_init () != SNORKEL_SUCCESS)
{
perror ("could not initialize snorkel\n");
exit (1);
}
/*

if (!http)
{
perror ("could not create http server\n");
exit (1);
}

/*

{
fprintf (stderr, "could not create listener\n");
snorkel_obj_destroy (http);
exit (1);
}

exit (1);
}

if (snorkel_obj_set(http, snorkel_attrib_ipvers, IPVERS_IPV4, SOCK_SET) != SNORKEL_SUCCESS)
{
fprintf (stderr, "error could not set ip version\n");
exit (1);
}

/*

fprintf (stderr, "\n\n[HTTP] starting embedded server\n");
if (snorkel_obj_start (http) != SNORKEL_SUCCESS)
{
perror ("could not start server\n");
snorkel_obj_destroy (http);
exit (1);
}

fgets (szExit, sizeof (szExit), stdin);

fprintf (stderr, "[HTTP] bye\n");

/*

*/
snorkel_obj_destroy (http);
exit (0);
}

So, I just want to change the HTML code which displays : Dynamic Content in the browser, to displaying my image.jpg

hiyes, i just did, but still the same problem exists "unable to open file"

const char * EncQR = Extract_ClientPublicKey_Encrypt_QRcode(str, ClientCert_String);

ofstream myfile1;
myfile1.open("ram.txt");
if (myfile1.is_open())
{
myfile1 <<EncQR<<"\n";
myfile1.close();
}
else
cout<<"Unable to open file";

thank you for replying, and sorry for not getting it right :(
But when adding the (*.c) files from the LibQREncode folder into my project, and compiling the project (Make and Build), i get a lot of syntax and declaration errors, with regard to the .c files i've added.
My questions are:
1- Do i COPY these files to the project folder only, or should i ADD them into the project, because i think they must not be changed.
2- what are the library and DLL files i should link to my project

Thank you so much, and i really appreciate your help

raniam 17-Mar-14 7:07am View

Thank you, i've copied all the C files into my project directory and included all the (.h) files into my (.cpp), and the previous errors were gone. But another error came up, which is:
1- [ilink32 Error] Error: Unresolved external '_main' referenced from C:\PROGRAM FILES (X86)\EMBARCADERO\RAD STUDIO\10.0\LIB\WIN32\RELEASE\C0X32.OBJ

2- [ilink32 Error] Error: Unable to perform link

Even though, i'm working on a console application, but i dont know why i get this error
Need you help pleeeeeeeeeeeeeese
Best Regards.

raniam 17-Mar-14 6:08am View

I've added all the *.h files in my *.cpp, but the problem is that the package does not contain any *.lib nor *.dll files.
So what can i do?

Regards.

raniam 17-Mar-14 6:07am View

thank you for replying, but this is my first time to use a code from another vendor.
how can i build the library? since the package does not contain any *.Lib or *.Dll files!

And i'm using C++ Builder XE3 (not VC++)
Regards.

NS2 is a Network Simulator. it's a discrete event simulator targeted at networking research. Ns-2 provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless (local and satellite) networks.

raniam 25-May-13 4:57am View

yes thank you, I've made a copy of the digitalSignature and it worked

raniam 23-May-13 8:47am View

This is the function that generates the Digital Signature:

const char * CLIENT::Generate_RSA_DigitalSignature(const char * MNumber, CkCert * DigSig_Dig_Certificate1)
{
CkPrivateKey *pkey = 0;
pkey = DigSig_Dig_Certificate1->ExportPrivateKey();
if (pkey == 0 ) {
printf("%s\n",DigSig_Dig_Certificate1->lastErrorText()); }

const char * pkeyXml;
// Get the private key in XML format:
pkeyXml = pkey->getXml();
//delete pkey;
//cout<<"\n"<<pkeyXml;
CkRsa rsa;

// Any string argument automatically begins the 30-day trial.

bool success = rsa.UnlockComponent("***********************");
if (success != true) {
printf("RSA component unlock failed\n"); }

// Import the private key into the RSA component:
success = rsa.ImportPrivateKey(pkeyXml);
if (success != true) {
printf("%s\n",rsa.lastErrorText()); }

cout<<"\nPrivate Key: "<<pkeyXml<<"\n";
// This example will sign a string, and receive the signature
// in a hex-encoded string. Therefore, set the encoding mode
// to "hex":
rsa.put_EncodingMode("hex");

// If some other non-Chilkat application or web service is going to be verifying
// the signature, it is important to match the byte-ordering.
// The LittleEndian property may be set to true
// for little-endian byte ordering,
// or false for big-endian byte ordering.
// Microsoft apps typically use little-endian, while
// OpenSSL and other services (such as Amazon CloudFront)
// use big-endian.
rsa.put_LittleEndian(false);

// Sign the string using the sha-1 hash algorithm.
// Other valid choices are "md2" and "md5".
const char * hexSig;
hexSig = rsa.signStringENC(MNumber,"sha-1");

//printf("%s\n",hexSig);

//printf("Success!\n");
return hexSig;
}

and this is the main function that calls the Generate_RSA_DigitalSignature function:

int _tmain(int argc, _TCHAR* argv[])
{
cout<<"CLIENT SIDE\n";
cout<<"===========\n\n";

CkCert * c = browser.Pass_Certificate();
//printf("%s\n",c->subjectDN());

CkString cert = browser.Convert_Cert_into_String(c);
cout<<cert;

HANDLE hConsole3;
hConsole3 = GetStdHandle (STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hConsole3, 10);
char mn[4096];
printf("ENTER YOUR MOBILE NUMBER:");

HANDLE hConsole4;
hConsole4 = GetStdHandle (STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hConsole4, 14);
gets(mn);

const char * Digital_Signature = browser.Generate_RSA_DigitalSignature(mn, c);
cout<<"\nDigital Signature: \n"<<Digital_Signature;

//CONNECTION 1 (client.h)
//************************
//SSL conncection between the "PC as a client" and the "MERCHANT as a server"
int a = browser.SSL_client_side(mn,true,Digital_Signature,cert);
cout<<"\n\n";

getch();
}

Thank you, i've tried it on C++ Builder XE3, and it worked.
But i dont know why it was not working on C++ Builder6

Regards.

raniam 5-Mar-13 8:27am View

HI,,

I've tried your advice and disabled the firewall, but it didnt work either,
Did you add the two files in a single project!!!!, can you please tell me exactly how you did it, because i'm a beginner in socket programming???
How can i use the localhost IP address?

best regards.
