e1a6b5eb03 DOC: Un-document the ability to use bytes with encoding(octet). 
This usage is now considered deprecated. Use strings instead for
greater efficiency and type consistency in your applications.

This functionality is a candidate for removal in a future commit.

Markus Triska
4ebdd97ad3 DOC: Improve descriptions to make clear what encoding(octet) means. 
In particular, octet does *not* mean that the input is a list of
Prolog bytes in the sense of "integers between 0..255", but that the
character codes are used directly as byte values.

ec251b254c ENHANCED: Safe HMAC verification, using constant time string comparison. 
Without this provision, the expected HMAC can be gathered from timing
differences depending on the position where the strings first diverge,
and hence an attacker can forge an authenticated message by supplying
the gathered HMAC.

Test case, using exp(E) to succeed exactly 2^E times:

    exp(E) :-
        N is 2^E,
        between(1, N, _).

yielding:

    ?- Options = [algorithm(sha512),hmac([1,2,3])],
       Ds = "test",
       crypto_data_hash(Ds, H, Options),
       phrase((seq(As),seq(Bs)), H),
       same_length(Bs, Cs),
       maplist(=(a), Cs),
       append(As, Cs, H1),
       time((exp(10),crypto_data_hash(Ds, H1, Options),false)).
