anybody knows a GOOD Platform Independent EASY TO USE C++ md5 librery
Are you asking in relation to http://cboard.cprogramming.com/showthread.php?t=105493
Nope Thats a C lib not C++ and That one I've got for C++ is not good at all.
It was messing the header files names and lots of C code in C++ which refuses to compile due bad structure.
as I am not getting any C++ lib I am trying to understand this C one which atleast compiles.
However I dont want to use any lib that user need to install to get a DLL or so which will will be dynamically linked.
I want a C++ Code that I can statically Compile with my programm.
Thats why I cant simply use mhash cause its hard to extract the md5() code from it.
Perhaps wrap the C code in a C++ class of your own.
Sooner or later, you'll want to do this yourself, so consider this an opportunity to learn.
It's not like MD5 has a complicated interface or anything.
anyway but I've made that semi broken C++ implementation working by borrowing some codes from the C version.
hashlib++ seems to work OK, too.
Could someone please show some sample code that I could run using hashlib++(or a similar hashing function that uses MD5)?
I am very new to programming!
Thanks
Download the hashlib++ library; there are examples contained in the package.
Thank you for your help, but when I run md5example.cpp I get many errors such as:
md5example.cpp:1:23: hashlibpp.h: No such file or directory
md5example.cpp:8: error: expected constructor, destructor, or type conversion before '*' token
md5example.cpp:8: error: expected `,' or `;' before '*' token
md5example.cpp:10: error: expected unqualified-id before "try"
md5example.cpp:10: error: expected `,' or `;' before "try"
md5example.cpp:22: error: expected unqualified-id before "catch"
md5example.cpp:22: error: expected `,' or `;' before "catch"
md5example.cpp:32: error: expected unqualified-id before "delete"
md5example.cpp:32: error: expected `,' or `;' before "delete"
Any ideas??
Thanks!
Don't delete hashlibpp.h before you start? (Or, alternatively, put in the directory along with everything else, or make sure you download it in the first place.)
I did think it was very odd for me to get an error saying "md5example.cpp:1:23: hashlibpp.h: No such file or directory"
I changed the top of the code to
That problem is gone, however I now get:Code:#include <string.h>
#include <iostream.h> //for "cerr"
include "hashlibpp.h"

I don't understand!!
Using iostream.h is evil and a sin. The header is called <iostream>, no .h at the end.Quote:

Thanks for the tips. The following code:
Code:#include <string.h>
#include <iostream> //for "cerr"
#include "hashlibpp.h"
generates the following error messages:

Did you type "g++ md5wrapper.cpp md5.cpp" on the command line, or just md5.cpp?Quote:

Thank you so much. This seems to have done the trick and I no longer get error messages. However, when I run the program, I get nothing from the output. How can I print out what the MD5 hash for "Hello World" is? Is the hash stored in the variable hash1?Quote:

Code:#include "md5wrapper.h"
int main( int argc, char** argv )
{
// creating a wrapper object
md5wrapper md5;
// create a hash from a string
std::string hash1 = md5.getHashFromString("Hello World");
// create a hash from a file
std::string hash2 = md5.getHashFromFile("readme.txt");
return 0;
}
Yes, if you want to see it, you'll need to send that string to cout.Quote:
