including a source file is not optimal

putting crypto primitives in a library makes perfect sense

the place for this is not libc but a crypto library like
libopenssl, libtomcrypt, libgcrypt, etc

unfortunately most of these are not well-structured or
well-maintained which is important for crypto code

there are various high quality but half baked solutions
(like nacl of djb or the kripto lib that came up on this
list earlier, neither of them are widely used/deployed)
