Jack O'Connor a0d7b4f3f8 merge the C code's ci.yml into the top level one 
CI is not currently working due to quota issues, so I'll need to check
that this is actually working later.

Jack O'Connor dc324a189e add the guts module to share code with Bao 2019-12-29 11:55:19 -06:00
Jack O'Connor 2fac7447e0 make derive_key take a key of any length 
The previous version of this API called for a key of exactly 256 bits.
That's good for optimal performance, but it would mean losing the
use-with-other-algorithms property for applications whose input keys are
a different size. There's no way for an abstraction over the previous
version to provide reliable domain separation for the "extract" step.
 2019-12-28 17:56:29 -06:00
Jack O'Connor ba28064963 switch back to counting trailing 0 bits 
These things are totally equivalent, and I keep going back and forth,
but now I think this is slightly clearer.
 2019-12-24 16:51:43 -06:00
Jack O'Connor c9ffbdd365 use self.flags instead of self.chunk_state.flags in the reference impl 
This is clearer, and because of padding requirements it doesn't change
the size of the Hasher struct. (We have a test for this.)

Jack O'Connor 8aae07f91a switch from counting trailing 0 bits to counting trailing 1 bits 2019-12-24 13:12:18 -06:00
Jack O'Connor 6c1155a41d get rid of unnecessary variables in push_chunk_chaining_value 2019-12-23 15:47:40 -06:00
Jack O'Connor 3016ddcb3a add a parent_cv helper function to the reference impl 
Also use fewer array references (the compiler doesn't care) be more
explicit with a `new_cv` mutable variable. This clarifies
push_chunk_chaining_value just a bit. Since that's the trickiest
function in the entire thing, it's good to clarify it. (It also gets
excerpted directly into the spec.)

Jack O'Connor 021c7b66be switch to simplified rotations 
This is a performance improvement on modern x86 chips (Skylake and
later), and the LLVM optimizer can convert these to AVX-512 rotations
when those are enabled.
