Where is that god damn MD5 lib?

Trying to link your code that uses MD5_Init(&ctx), MD5_Update() and MD5_Final(md5_sum, &ctx), but you just can not find the library that provides the function on Linux? <br />
Well - it is lib openssl, http://www.openssl.org/.

Iclude header:  #include <openssl/md5.h>
Link your code with:  -lssl.
