The ENOKEY error is due to an accept() at the wrong location. But I do not see 
that error:

tar xvfJ libkcapi-0.14.0.tar.xz
cd libkcapi-0.14.0
autoreconf -i
./configure --enable-kcapi-hasher
make
cd bin/.libs/ # I make no make install for testing
ln kcapi-hasher md5sum # create md5sum app
export LD_LIBRARY_PATH=../../.libs/ # location of current library

$ ./md5sum md5sum 
ddd1a82680b16fb6c241d81656b844df  md5sum

So, it works for me.

Can you please check whether you use the current library version? Note, 
library version 0.10.1 fixed the aforementioned accept() call for kernel 4.4 
and later.

$ ./md5sum -v
md5sum: libkcapi 0.14.0

Ciao
Stephan
