Jonathan Protzenko	325e9b8ef4	gh-99108: Add HACL* Blake2 implementation to hashlib (GH-119316) ... 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`.	2024-08-13 21:42:19 +00:00
Jonathan Protzenko	872e212378	gh-99108: Refresh HACL*; update modules accordingly; fix namespacing (GH-117237) ... Pulls in a new update from https://github.com/hacl-star/hacl-star and fixes our C "namespacing" done by `Modules/_hacl/refresh.sh`.	2024-03-26 00:35:26 +00:00
Jonathan Protzenko	15665d896b	gh-99108: Replace SHA3 implementation HACL* version (#103597) ... Replaces our built-in SHA3 implementation with a verified one from the HACL* project. This implementation is used when OpenSSL does not provide SHA3 or is not present. 3.11 shiped with a very slow tiny sha3 implementation to get off of the <=3.10 reference implementation that wound up having serious bugs. This brings us back to a reasonably performing built-in implementation consistent with what we've just replaced our other guaranteed available standard hash algorithms with: code from the HACL* project. --------- Co-authored-by: Gregory P.

Jonathan Protzenko	fcadc7e405	gh-99108: Import MD5 and SHA1 from HACL* (#102089) ... Replaces our fallback non-OpenSSL MD5 and SHA1 implementations with those from HACL* as we've already done with SHA2.	2023-02-22 13:18:43 -08:00
Gregory P. Smith	d777790bab	gh-99108: Build the hashlib HACL* code as a static library. (#101917) ... This builds HACL* as a library in one place. A followup to #101707 which broke some WASM builds. This fixes 2/4 of them, but the enscripten toolchain in the others don't deduplicate linker arguments and error out. A follow-on PR will address those.	2023-02-14 15:57:01 -08:00
