* simplify HACL* build for MD5, SHA1, SHA2 and SHA3 modules
* remove statically linked libraries for HACL* implementation
* is it better now?
* is it better now?
* fixup
* Present HACL* as a static or shared library.
On WASI, extension modules based on HACL* require the HACL*
library to be linked statically. On other platforms, it can
be built dynamically.
* amend whitespace
* remove temporary .so file as it requires more symlinks
* avoid smelly symbols
* fixup checksums
* regen sbom
* fixup shell warnings and comments
* it *should* work
This replaces the existing hashlib Blake2 module with a single implementation that uses HACL\*'s Blake2b/Blake2s implementations. We added support for all the modes exposed by the Python API, including tree hashing, leaf nodes, and so on. We ported and merged all of these changes upstream in HACL\*, added test vectors based on Python's existing implementation, and exposed everything needed for hashlib.
This was joint work done with @R1kM.
See the PR for much discussion and benchmarking details. TL;DR: On many systems, 8-50% faster (!) than `libb2`, on some systems it appeared 10-20% slower than `libb2`.
