c++ include md5

I would like write a program that will generate md5 sums based on files I will feed it. But I do not know how to include md5 capability into my program. What libraries should can I use and how do I implement them? Can anyone give me some recommendations? All it needs to do is take a file input, generate the sum, and return the string of the md5 sum. Simple huh?

You should include crypt.h

Also for simple operations on md5sum, you can just call the md5sum executable using the system() command.

The GNU coreutils contain the source for the command line md5sum program.

Thanks. I tried that, but it seems I am missing something. I copied and pasted the example code from that website and my compiler gave me the error:

Code:

undefined reference to crypt

My program has #include<crypt.h> and that does not give an error....

About the system call, yeah. I know I could do that but I really would rather not, since it may be used on other systems eventually.

Maybe you need to pass a linker flag like -lcrypt while compiling?

Just a thought.

That worked, thanks!
