I'd actually tried the authors, but no reply yet (only a few days). I also 
tried the RFC Editor thinking they might have e.g. XML from which extraction 
might have been easier, but also no response yet. And I had found several 
libraries, but not the RFC code. I can't see any suggestion that the library 
you indicate includes that code, it also bills itself as a C++ library, which 
the RFC code is not (and also not what I want, but that's not a subject for 
this list).

But the broader point is that if it's worth the IETF publishing the code as an 
RFC, it's worth making the code available straightforwardly.

For me, a thanks to Tony Hansen, who did the extraction for me. (That makes me 
feel a little guilty, why should he do my work I could have done?) But the 
point of posting on this list was to say that the code should be available so 
that each person wanting that code doesn't have to do that again.

Ok, other than time, it should be easy to extract, clean up and cross 
your fingers that it compiles with your favorite C compiler.  But I 
would write to the authors to get the original source. Or google:

     C source crypto libraries API hashing functions

among the first hit:
