Openssl
 

I am writting a small hash program. I want to use the MD5, functions present in <openssl/md5.h>. I don't know how to compile my code after inluding these headers. When I include the MD5() function, it says "undefinied reference to MD5". What flags shud I use during compilation ?

I would imagine you need to have "-lssl" or "-lopenssl" depending on the name of the library installed on your system.
