Jack O'Connor efbfa0463c integrate assembly implementations into the blake3 crate 2020-02-12 10:23:17 -05:00
Jack O'Connor 92d421dea1 add a larger test case 
One thing I like to test is that, if I hack simd_degree to be higher
than MAX_SIMD_DEGREE, assertions fire. This requires a test case long
enough to exceed that number of chunks.

Jack O'Connor b04974461a include the right context string in the test_vectors.json comment 
I must've written the comment one way, and then changed the context
string later, without realizing that I'd copied it. Apologies to
everyone whose time I wasted with this.

Fixes https://github.com/BLAKE3-team/BLAKE3/issues/15.

Jack O'Connor bef2034c0b fix cross_test.sh 
This is a hacky test script, and it broke when I added a feature flag,
while our CI was past quota :(

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.

Jack O'Connor b5f1e925f7 rename "offset" to "counter" and always increment it by 1 
This is simpler than sometimes incrementing by CHUNK_LEN and other times
incrementing by BLOCK_LEN.

Jack O'Connor a5cc3b2867 reduce the CHUNK_LEN from 2048 bytes to 1024 bytes 
Smaller chunk sizes are a big benefit for parallelism at shorter input
lengths, and recent benchmarks show that this reduction has a relative
small cost in terms of peak throughput. It's also a nice round number.
